Patented & Patent Pending Technology for camera/video recorders RAYNAULD™ DIRECTIVITY COLOR CALIBRATION FILTER 雷諾指向式色彩定位鏡 What is “RAYNAULD™ Directivity Color Calibration Filter”? (DCC Filter)“RAYNAULD™ Directivity Color Calibration Filter” is a newly invented external camera optical filter, which allows the most demanding professional photographers to capture a scene’s “Absolute Color” or “Visual Color” using the camera’s manual white balance system to achieve the highest photographic color accuracy in all lighting condition. This dramatically reduces the steps and the time required in post-processing for color enhancements. It helps to remove the doubt and uncertainness on photo color accuracy.  This also benefits general photography public by shooting the near-to-perfect color photos or videos at profession levels anytime anywhere! “RAYNAULD™ Directivity Color Calibration Filter” is a most advanced optical filter for calibrating the camera color system on site. It is used to pin-point calibrate the camera gray system against various scenes with exact accurate compensation value before the shooting. As a result, we have a high-precision and rich in detail photo with well-structured rich colors. Despite its complex physic and optical theory, the DCC Filter has an elegant and simple design. It is easy to use with and works with remarkable results.“RAYNAULD™ Directivity Color Calibration Filter” is used to limit the range of photographic field to proceed with the color compensation towards the camera gray card system. In return, it achieves the highest color accuracy and an unprecedented life color reproduction of photos.  It does not only achieve the simple white color balance to restore the photos to the standard color temperature (e.g. 6500K or 5500K) afterwards. By doing so, all the colors in the photo will be twisted to inaccurate color when the rendered white color is forced to the standard white color!Under different lighting conditions, the absolute standard white color is rendered into different color gradation of white as being affected by ambient lights. The “RAYNAULD™ Directivity Color Calibration Filter” is very effective to achieve the most accurate color reproduction under this shooting scene.  Based on its design, DCC Filter works very well with either JPG or RAW form on all brands of cameras.Features of RAYNAULD Directivity Color Calibration Filter Purposes and users of RAYNAULD™ DCC Filter What is the main function of RAYNAULD™ DCC Filter?

DIRECTIVITY COLOR CALIBRATION FILTER)DCC FILTER BACKGROUND OF THE INVENTION1.    Field of the Invention:The present invention relates to image pick-up technology, and more particularly, to a barrel-based white balance filter, which comprises an opaque barrel, and a white balance component axially adjustably mounted in the opaque barrel. The invention uses the opaque barrel to isolate the color temperature beyond the viewing scene, and allows adjustment of the proportion of the amount of the color temperature of the main light source using the light transmissive property of the white balance filter of the white balance unit, achieving the effect of increasing or reducing the average color temperature like the functioning of the eyelid to adjust the intraocular pressure subject to the brightness of the main light source so that the color is closer to the human eye visual sense and personal preferencesDescription of the Related Art:White a balance filter plate (7) or white balance lens cap (6) with a filter (61) may be used with a camera (2). During application, as illustrated in FIGS. 13, 14 and 15, the balance filter plate (7) or white balance lens cap (6) is attached to the camera lens (21) of the camera (2), and then the shutter is pressed to run the manual white balance mode, getting the average white balance value of the viewing scene. This average white balance value is used as a single color temperature for photographing.Red, blue and green are three most basic colors that can be combined to make a useful range of colors. For human applications, these three primary colors are usually used, since human color vision is trichromatic. Only the values of these three primary colors are equal to each other, R = B = G, the correct white can be presented in the human vision. If white is accurately corrected or displayed, all other colors of photos or videos can be presented correctly in the human vision.The manual white balance mode of a camera is to accurately measure the average color temperature of the viewing scene for use as a color temperature reference value so that accurate colors can be exhibited in the artworks, greatly reducing further software color temperature revising works. Because the colors of photos or videos having an incorrect color temperature are inconsistent with the scene of the photography site, the high-precision human visual system can easily senses the differences, all camera artworks in incorrect color are failed artworks to all people.Each single picture of photos, videos, or live videos is presented in the human vision based on a single color temperature. The human vision can instantly senses any change or error of the color temperature. Therefore, getting the color temperature value of the scene is one of the most important works of the success of the artwork.However, attaching a conventional white balance filter plate (7) or white balance lens cap (6) for a manual white balance operation cannot accurately get the color temperature and colors of the photography scene due to poor overall design of the white balance filter plate (7) or white balance lens cap (6). When facing the white balance filter plate (7) or white balance lens cap (6) toward the viewing scene, all the surrounding lights and colors non-selectively fall upon the filter to make an incorrect average color temperature value.Actually, every color of a physical object has its particular color temperature value under every light source. When changing the shooting direction of the camera during photographing, the composition of the photograph range and color ratio are relatively changed, and the average color temperature value of each picture is also changed. So, only focus on the area of the scene to be photographed can get the most precise average white balance value.In an outdoor operation, the scene taken by the camera (2) depends upon the view angle and distance of the focus of the camera lens (21). Photographing has its scene range. During application of the white balance filter plate (7) or white balance lens cap (6), unnecessary ambient light beyond the viewed range will be received, such as sunlight, reflected light from the blue sky and white clouds can fall upon the white balance filter plate (7) or white balance lens cap (6) to mix with the incident light from the viewing scene, causing the camera (2) to get an incorrect average color temperature value for photographing. Based on this incorrect average color temperature value, a color shift problem will occur in the photos or videos thus obtained.During an indoor photography operation, all the outdoor or indoor main light source and other ambient and reflected light rays and colors from all directions will fall upon the white balance filter plate (7) or the filter (61) of the white balance lens cap (6) and enter the color temperature sensing range of the light transmissive structure thereof, giving an incorrect average white balance value to the manual white balance system, resulting in photo color distortion.In addition to general photography purposes, getting the accurate colors of objects is also very important in scientific research, color management, typography or recording works, for example, to obtain a reference color of an object at different locations or under different light source environments for color calibration to achieve consistency.SUMMARY OF THE INVENTIONThe present invention has been accomplished under the circumstances in view. It is therefore the main object of the present invention to provide a measure capable of getting the correct average white balance in a simple, rapid and low-cost manner. A barrel-based white balance filter of the present invention comprises a white balance unit that comprises a barrel and a white balance component axially adjustably mounted in the barrel. The barrel is prepared from an opaque material and attachable to a camera lens of a camera directly or by means of an engagement thread thereof. The white balance component is a milky white or gray filter having a milky white or gray annular rim axially extended from the periphery thereof, and mounted in the barrel and axially movable relative to the barrel between an extended position and a fully received position. Thus, adjusting the position of the white balance component relative to the opaque barrel causes change in the received color light gradually. When the white balance component is moved to the position where the annular rim suspends outside the opaque barrel, the amount of ambient color light received by the milky white or gray filter is greatly increased, and the surrounding color light beyond the viewing scene that falls upon the annular rim is guided into the milky white or gray filter to regulate the color temperature value.Further, when the white balance component is in the fully received position, the milky white or gray annular rim is completely received in the barrel and protected by the opaque barrel against the radiation of vivid light or reflected light during a manual white balance operation, enabling a manual white balance system of the camera using the barrel-based white balance filter to measure the average white balance value of the viewing scene accurately.Further, by means of the high precision white balance filter, the barrel-based white balance filter of the present invention can accurately measure the color temperature value accurately from a far distance for adjusting the color balance and color density, achieving perfect color temperature setting in JPG or RAW files so that the user can instantly upload perfect color photos for sharing.Further, the design of the barrel of the barrel-based white balance filter facilitates convenient use. When using the manual white balance mode, the barrel-based white balance filter can be directly attached to the camera lens, preventing intake of vivid light and color beyond the viewing range to affect color temperature measuring accuracy.RIEF DESCRIPTION OF THE DRAWINGSFIG. 1 is an exploded view of a barrel-based white balance filter in accordance with a first embodiment of the present invention.FIG. 2 illustrates the barrel-based white balance filter of the first embodiment of the present invention attached to the camera lens of a camera.FIG. 3 is a schematic sectional applied view of the first embodiment of the present invention, illustrating the white balance filter adjusted relative to the opaque barrel.FIG. 4 is an exploded view of an alternate form of the first embodiment of the present invention, illustrating the opaque barrel provided with an engagement thread for engagement with an engagement groove around the periphery of a front end of a camera lens of a camera.FIG. 5 is a sectional installed view of an alternate form of the first embodiment of the present invention, illustrating the use of a flat glass type white balance filter.FIG. 6 is a sectional installed view of a barrel-based white balance filter with a telescopic barrel in accordance with a second embodiment of the present invention.FIG. 7 corresponds to FIG. 6, illustrating the telescopic barrel of the barrel-based white balance filter fastened to a camera lens of a camera.FIG. 8 corresponds to FIG. 7, illustrating the telescopic barrel in the received status.FIG. 9 is an elevational view of a barrel-based white balance filter fastened to a smart phone in accordance with a third embodiment of the present invention.FIG. 10 illustrates the barrel-based white balance filter of the third embodiment of the present invention fastened to a tablet computer.FIG. 11 illustrates a detachable type barrel-based white balance filter used in a camera in accordance with a fourth embodiment of the present invention.FIG. 12 illustrates the detachable type barrel-based white balance filter of the fourth embodiment of the present invention equipped with a wireless circuit and a battery and mounted at a camera tripod for wireless communication with a camera or smart phone.FIG. 13 illustrates a white balance device for use with a camera according to the prior art.FIG. 14 corresponds to FIG. 13, illustrating the white balance device attached to the camera lens of the camera.FIG. 15 illustrates the use of another prior art design of white balance device with a camera.DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTReferring to FIG. 1, 2 and 3, a barrel-based white balance filter in accordance with a first embodiment of the present invention is shown. The barrel-based white balance filter comprises a white balance unit (1) that comprises a barrel (11) and a white balance component axially adjustably mounted in the barrel (11). The barrel (11) is made from an opaque material, and configured to be directly pres-fitted onto the lens (21) of a camera (2). Alternatively, the barrel (11) can be configured to provide an engagement thread (113) for engagement with an engagement groove (211) around the periphery of the front end of the camera (2) (see FIG. 4). The white balance component is a milky white or gray filter (12) having an annular rim (121) axially extended from the periphery thereof and insertable into the bore (111) in the barrel (11) for allowing adjustment of the position of the milky white or gray filter (12) relative to the barrel (11) in axial direction. When pushed the milky white or gray filter (12) to the position where the annular rim (121) is completely received in the bore (111) of the barrel (11), the milky white or gray filter (12) is received in and shielded by the opaque barrel (11). Thus, during the operation of the camera (2) under the manual white balance mode, the milky white or gray filter (12) is well protective by the opaque barrel (11) against the radiation of vivid light or reflective light, and thus, the manual white balance system of the camera (2) can measure the average white balance value of the viewing area accurately. Further, the milky white or gray filter (12) can be configured having a six-star sword head protrusion at the center to assist focusing of the lens (21). Further, the closer the position of the milky white or gray filter (12) to the core (111) of the barrel (11) is, the larger the amount of color light received will be. Adjusting the position of the milky white or gray filter (12) relative to the barrel (11) causes change in the received color light gradually. When the white-balance filter (1) is moved axially toward the outside of the bore (111) of the barrel (11) to have the annular rim (121) suspend outside the bore (111) of the barrel (11), the amount of ambient color light received by the milky white or gray filter (12) is greatly increased, and the surrounding color light beyond the scene of the viewing window that falls upon the annular rim (121) outside the bore (111) of the barrel (11) is guided into the milky white or gray filter (12) to regulate the color temperature value. Further, stop flanges (122)(112) are respectively provided at the rear side of the milky white or gray filter (12) and the orifice of the bore (111) of the barrel (11) for stopping against each other to prohibit the milky white or gray filter (12) from falling out of the barrel (11). Further, the milky white or gray filter (12) can be made a flat glass filter mounted in the bore (111) of the barrel (11) for receiving the color light of the scene viewed through the viewing window of the camera (2), obtaining an accurate average white balance value (see FIG. 5).Referring to FIGS. 6, 7 and 8, a barrel-based white balance filter in accordance with a second embodiment of the present invention is shown. In this second embodiment, the barrel (13) is a telescopic design, comprising a plurality of barrel components (131) that slide one inside another. The milky white or gray filter (12) with the annular rim (121) is slidably coupled to the front side of the barrel (13). Thus, the barrel-based white balance filter can be adjusted axially to extend or shorten the length for carrying or storage conveniently. Further, stop flanges (132)(133)(122)(123) are respectively provided at opposing front and rear sides of each of the barrel components (131) and the milky white or gray filter (12) to prohibit the barrel components (131) and the milky white or gray filter (12) from disconnection.Referring to FIGS. 9 and 10, a barrel-based white balance filter in accordance with a third embodiment of the present invention is shown. The white balance unit (1) formed of the barrel (11) and the milky white or gray filter (12) having an annular rim (121) is mountable at the front side of a camera lens (31)(41) of a smart phone (3) or tablet computer (4). When using the smart phone (3) or table computer (4) to take pictures under the manual white balance mode, the milky white or gray filter (12) is well protected by the barrel (11) against the radiation of vivid light or reflective light, enabling the manual white balance system of the smart phone (3) or tablet computer (4) to measure the average white balance value of the scene viewed. Further, the barrel-based white balance filter of this third embodiment comprises a fastening device (5) for securing the barrel (11) of the white balance unit (1) to the front side of the camera lens (31)(41) of the smart phone (3) or tablet computer (4).Referring to FIG. 11, a barrel-based white balance filter in accordance with a fourth embodiment of the present invention is shown. This fourth embodiment is used in a detachable white balance color temperature measurement device (8). The detachable white balance color temperature measurement device (8) comprises a color temperature sensor (81) mounted in an outer shell thereof, and a plug (811) disposed outside the outer shell for transmitting power supply and signals. The plug (811) can be plugged into a mating jack (221) at the camera body (22) or camera lens (21) of a camera (2), vivid camera, smart phone (3) or tablet computer (4). The white balance unit (1) formed of a barrel (11) and a milky white or gray filter (12) having an annular rim (121) is mounted in the front side of the detachable white balance color temperature measurement device (8). When using the camera (2), video camera, smart phone (3) or table computer (4) to take pictures under the manual white balance mode, the milky white or gray filter (12) is well protected by the barrel (11) against the radiation of vivid light or reflective light, and the color temperature sensor (81) senses the color temperature, enabling the manual white balance system of the camera (2), video camera, smart phone (3) or tablet computer (4) to measure the average white balance value of the scene viewed.Further, a wireless circuit (82) and a battery (83) can be mounted in the detachable white balance color temperature measurement device (8). During application, the detachable white balance color temperature measurement device (8) is mounted on a tripod (84) for measuring the average white balance (color temperature) value of the scene and transmitting the measured average white balance (color temperature) value to a CPU (Central Processing Unit) of a camera (2), video camera, smart phone (3) or tablet computer (4) for processing through a white balance arithmetic process to get an accurate white valance (color temperature) value (see FIG. 12).In conclusion, the invention provides a barrel-based white balance filter comprising a white balance unit that comprises an opaque barrel and a white balance component axially adjustably mounted in the opaque barrel. The invention uses the opaque barrel to isolate the color temperature beyond the camera scene, and allows adjustment of the proportion of the amount of the color temperature of the main light source using the light transmissive property of the white balance filter of the white balance unit, achieving the effect of increasing or reducing the average color temperature like the functioning of the eyelid to adjust the intraocular pressure subject to the brightness of the main light source so that the color is closer to the human eye visual sense and personal preferencesAlthough particular embodiments of the invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention.

【0002】    按,目前的平板式白平衡濾鏡片(7)及具濾鏡(61)之白平衡鏡頭蓋(6)的使用方式,如第十三圖、第十四圖及第十五圖所示,是對著攝影區域把它們放置 在攝像機(2)鏡頭(21)前,再以按快門進行手動白平衡,以求取攝影現場的白平衡平均值,用該值作為攝影的單一色溫值,以進行攝影工作。

【0003】    白色是一切顏色的基本,是由紅(Red)、藍(Blue)、綠(Green)組合而成,祇有在三基色色值彼此相同時,R=B=G,才能把白色正確顯示出來在人類的視覺,白色校正或顯示正確了,相片、影片的其他所有顏色才能正確顯示在人的視覺。

【0004】    攝像機(2)的手動白平衡目的,在正確取得攝像場景的平均色溫值,以其為拍攝的色溫標準值而將正確色彩表現在其作品上,可以大幅度減少其在事後以軟體修 正不正確色溫值的作品,因為色溫值不正確的相片、影片的色彩與攝影現場不一致,人類高精密視覺系統能輕易分別其中的差異,色彩表現不正確的攝像作品對所有 的人而言都是失敗之作。

【0005】    相片、影片或現場視頻傳送的每一幅畫面都是以單一色溫作為色彩的根據表現在人類的視覺,色溫稍有改變或不正確時,人類視覺立刻可以感覺畫面上色彩的變化,所以進行攝像得到拍攝場景的精準色溫值是作品成敗最重要的工作之一。

【0006】    然而利用外置白平衡濾鏡片(7)、白平衡鏡頭蓋(6)進行手動白平衡動作,卻不能取得拍攝場景正確的色溫值和色彩,其原因出自外置白平衡濾鏡片(7)、 鏡頭蓋的整體設計不良所致,當面對攝像場景時,攝像機外的所有光線和顏色全都毫無選擇性投射在濾鏡片上而組合成不正確的平均色溫值。

【0007】    實質物體上的每一種顏色在每一種光源下有其獨特的色溫值,而攝像時每轉動其方向時,其攝像構圖的包括範圍的構成顏色比例各自不同,而每一攝像構圖的平均色溫值也各自不同,所以祇有針對攝像構圖的範圍才能得到最精準白平衡平均數值。

【0008】    以戶外為例,攝像機(2)的取景根據鏡頭(21)的焦距的視角和距離,而構圖取景拍攝,經常是有其範圍性,然而平板白平衡濾鏡片(7)、白平衡鏡頭蓋 (6)卻接收到攝像構圖範圍以外的不必要的光線,如陽光、天空藍光白雲的反射光線在白平衡濾鏡片(7)或白平衡鏡頭蓋(6)之濾鏡(61)上,而在白平衡 濾鏡片(7)或白平衡鏡頭蓋(6)之濾鏡(61)上構成不正確的構圖範圍的不正確平均色溫值,讓作手動白平衡運算的攝像機(2)得到與其攝像範圍內不正確 的色溫值去進行攝像動作,其拍攝出來的相片、影片的色溫色彩表現自然會有色偏現象了。

【0009】    而在室內攝影時,室內或室外主體光源、環境反射光線和顏色自四面八方投射在白平衡濾鏡片(7)或白平衡鏡頭蓋(6)之濾鏡(61)上,經由白平衡濾鏡片 (7)或白平衡鏡頭蓋(6)之濾鏡(61)本體組織的透光結構而進入色溫檢測範圍,如此給手動白平衡系統測得不正確的白平衡平均數值,而造成相片色彩失真 的現象,除了一般攝影用途,取得物品的準確色彩,在某些科學研究、色彩管理、排版印刷或紀錄是非常重要的,比如在不同的光源環境或地點獲取物品的標準顏 色,作色彩比較校正以取得一致性,因此,如何以簡單、快速及成本低來取得正確的白平衡平均數值是為本創作之主要目的。

【新型內容】

【0010】    <所欲解決之技術問題>

本 創作人有鑑於上述習知白平衡產品及設備之實用困難及有待改善之缺失,盼能提供一突破性之設計,以增進實用效果,乃潛心研思、設計組製,綜集其多年從事相關 產品設計產銷之專業技術知識與實務經驗及研思設計所得之成果,終研究出本創作一種套筒指向式白平衡濾鏡,以提供使用者。

【0011】    <解決問題之技術手段>

本 創作係包括一外筒體及一設於外筒體內可呈軸向位移調整之白平衡元件,其中該外筒體係為不透光材料製成,其可直接套接於鏡頭上,或藉卡齒與卡槽套組於鏡頭前 方,其中之白平衡元件係為一乳白色或灰色濾鏡,並於濾鏡周緣形成一亦呈乳白色或灰色延伸之環緣部,並使白平衡元件可套組進入前述外筒體內,並可於外筒體內 呈軸向位移調整,當使白平衡元件推移使其濾鏡包括環緣部完全隱入外筒體內時,將使白平衡元件之濾鏡僅接收視窗所見場景範圍內之色光,以得到準確白平衡數 值,且白平衡元件之位置越接近外筒體之內孔口,所接收外部之色光量則越多,並漸進產生變化,當將白平衡元件軸向推移至外筒體內孔口並使其延伸之環緣部露出 外筒體內孔口外,此時除濾鏡接受外部環境色光量增加外,其露出外筒體內孔口外之環緣部亦同時接收視窗場景以外之四週色光,並將所接收之色光藉導光作用將光 源傳導至濾鏡,進而改變進入濾鏡之外部環境光源色溫,進而達可得到準確白平衡數值或以微調方式得到不同色溫值之目的。

【0012】    <對照先前技術之功效>

本創作之主要目的係藉外筒體可以直接套在鏡頭上,把白平衡濾鏡放在不透光外筒體之內,利用套筒的遮蓋作用,使白平衡濾鏡作手動白平衡時,可以避免不必要的強烈光源或反射光直接照射在白平衡濾鏡上,使得攝像機手動白平衡系統可以測得取景區域更準確白平衡平均值。

【0013】    本創作之次一目的主要係藉高精準白平衡濾鏡,可遠距離準確測量色溫值,以調整色彩平衡與色彩密度,對於JPG或RAW檔色溫值一次就完美設定,毋須後製調整,立刻就可把色彩完美的相片上傳發表分享。

【0014】    本創作之另一目的在藉外筒體之設計,使用方便,祇在作手動白平衡時套在鏡頭使用就可以,可避免取景範圍以外的強光和顏色所帶來色溫測量失準現象。
