Patented & Patent Pending Technology for camera/video recorders RAYNAULD™ DIRECTIVITY COLOR CALIBRATION FILTER 雷诺指向式色彩定位镜 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.

【0003】    白色是一切颜色的基本,是由红(Red)、蓝(Blue)、绿(Green)组合而成,只有在三基色色值彼此相同时,R=B=G,才能把白色正确显示出来在人类的视觉,白色校正或显示正确了,相片、影片的其他所有颜色才能正确显示在人的视觉。

【0004】    摄像机(2)的手动白平衡目的,在正确取得摄像场景的平均色温值,以其为拍摄的色温标准值而将正确色彩表现在其作品上,可以大幅度减少其在事后以软体修 正不正确色温值的作品,因为色温值不正确的相片、影片的色彩与摄影现场不一致,人类高精密视觉系统能轻易分别其中的差异,色彩表现不正确的摄像作品对所有 的人而言都是失败之作。

【0005】    相片、影片或现场视频传送的每一幅画面都是以单一色温作为色彩的根据表现在人类的视觉,色温稍有改变或不正确时,人类视觉立刻可以感觉画面上色彩的变化,所以进行摄像得到拍摄场景的精准色温值是作品成败最重要的工作之一。

【0006】    然而利用外置白平衡滤镜片(7)、白平衡镜头盖(6)进行手动白平衡动作,却不能取得拍摄场景正确的色温值和色彩,其原因出自外置白平衡滤镜片(7)、 镜头盖的整体设计不良所致,当面对摄像场景时,摄像机外的所有光线和颜色全都毫无选择性投射在滤镜片上而组合成不正确的平均色温值。

【0007】    实质物体上的每一种颜色在每一种光源下有其独特的色温值,而摄像时每转动其方向时,其摄像构图的包括范围的构成颜色比例各自不同,而每一摄像构图的平均色温值也各自不同,所以只有针对摄像构图的范围才能得到最精准白平衡平均数值。

【0008】    以户外为例,摄像机(2)的取景根据镜头(21)的焦距的视角和距离,而构图取景拍摄,经常是有其范围性,然而平板白平衡滤镜片(7)、白平衡镜头盖 (6)却接收到摄像构图范围以外的不必要的光线,如阳光、天空蓝光白云的反射光线在白平衡滤镜片(7)或白平衡镜头盖(6)之滤镜(61)上,而在白平衡 滤镜片(7)或白平衡镜头盖(6)之滤镜(61)上构成不正确的构图范围的不正确平均色温值,让作手动白平衡运算的摄像机(2)得到与其摄像范围内不正确 的色温值去进行摄像动作,其拍摄出来的相片、影片的色温色彩表现自然会有色偏现象了。

【0009】    而在室内摄影时,室内或室外主体光源、环境反射光线和颜色自四面八方投射在白平衡滤镜片(7)或白平衡镜头盖(6)之滤镜(61)上,经由白平衡滤镜片 (7)或白平衡镜头盖(6)之滤镜(61)本体组织的透光结构而进入色温检测范围,如此给手动白平衡系统测得不正确的白平衡平均数值,而造成相片色彩失真 的现象,除了一般摄影用途,取得物品的准确色彩,在某些科学研究、色彩管理、排版印刷或纪录是非常重要的,比如在不同的光源环境或地点获取物品的标准颜 色,作色彩比较校正以取得一致性,因此,如何以简单、快速及成本低来取得正确的白平衡平均数值是为本创作之主要目的。

【新型内容】

【0010】    <所欲解决之技术问题>

本 创作人有鉴於上述习知白平衡产品及设备之实用困难及有待改善之缺失,盼能提供一突破性之设计,以增进实用效果,乃潜心研思、设计组制,综集其多年从事相关 产品设计产销之专业技术知识与实务经验及研思设计所得之成果,终研究出本创作一种套筒指向式白平衡滤镜,以提供使用者。

【0011】    <解决问题之技术手段>

本 创作系包括一外筒体及一设於外筒体内可呈轴向位移调整之白平衡元件,其中该外筒体系为不透光材料制成,其可直接套接於镜头上,或藉卡齿与卡槽套组於镜头前 方,其中之白平衡元件系为一乳白色或灰色滤镜,并於滤镜周缘形成一亦呈乳白色或灰色延伸之环缘部,并使白平衡元件可套组进入前述外筒体内,并可於外筒体内 呈轴向位移调整,当使白平衡元件推移使其滤镜包括环缘部完全隐入外筒体内时,将使白平衡元件之滤镜仅接收视窗所见场景范围内之色光,以得到准确白平衡数 值,且白平衡元件之位置越接近外筒体之内孔口,所接收外部之色光量则越多,并渐进产生变化,当将白平衡元件轴向推移至外筒体内孔口并使其延伸之环缘部露出 外筒体内孔口外,此时除滤镜接受外部环境色光量增加外,其露出外筒体内孔口外之环缘部亦同时接收视窗场景以外之四周色光,并将所接收之色光藉导光作用将光 源传导至滤镜,进而改变进入滤镜之外部环境光源色温,进而达可得到准确白平衡数值或以微调方式得到不同色温值之目的。

【0012】    <对照先前技术之功效>

本创作之主要目的系藉外筒体可以直接套在镜头上,把白平衡滤镜放在不透光外筒体之内,利用套筒的遮盖作用,使白平衡滤镜作手动白平衡时,可以避免不必要的强烈光源或反射光直接照射在白平衡滤镜上,使得摄像机手动白平衡系统可以测得取景区域更准确白平衡平均值。

【0013】    本创作之次一目的主要系藉高精准白平衡滤镜,可远距离准确测量色温值,以调整色彩平衡与色彩密度,对於JPG或RAW档色温值一次就完美设定,毋须后制调整,立刻就可把色彩完美的相片上传发表分享。

【0014】    本创作之另一目的在藉外筒体之设计,使用方便,只在作手动白平衡时套在镜头使用就可以,可避免取景范围以外的强光和颜色所带来色温测量失准现象。

【0015】    为使 贵审查委员能更了解本创作之结构特徵及其功效,兹配合图式并详细说明於后。
