Sleeve-pointing white balance filter

The present invention relates to a sleeve-directed white balance filter, and more particularly to an outer balance body and a white balance component disposed in the outer cylinder for axial displacement adjustment, by adjusting the white balance component in the outer cylinder The depth position, so that the white balance component only receives the color light in the scene range to obtain an accurate white balance value, or simultaneously receives the color light (color temperature) outside the scene range, thereby achieving a state in which the white balance component can receive the external color temperature, and then borrows The fine adjustment function can be used to obtain a color temperature ratio that can finely adjust the color temperature ratio of the main light source to match the eye feeling and personal visual preference.

Press, the current flat white balance filter lens (7) and the white balance lens cover (6) with the filter (61) are used as shown in the thirteenth, fourteenth and fifteenth figures. , placing them in front of the camera (2) lens (21) in front of the shooting area, and then manually balancing the white balance by pressing the shutter to obtain the white balance average of the shooting scene, and use this value as the single color temperature value of the shooting. For photography work.

White is the basic of all colors. It is composed of red, blue, and green. Only when the three primary colors are the same, R=B=G, the white can be correctly displayed. The human vision, white correction or display is correct, and all other colors of the photo and film can be correctly displayed in the human vision.

The manual white balance of the camera (2) aims to correctly obtain the average color temperature value of the camera scene, and display the correct color on the work with the color temperature standard value of the shooting. The work of correcting the incorrect color temperature value by software is greatly reduced. Because the color temperature value is not correct, the color of the film and the film are inconsistent. The human high-precision vision system can easily distinguish the difference and the color is not correct. The work is a failure for all people.

Each picture transmitted by a photo, video or live video is based on a single color temperature as a basis for color. In human vision, when the color temperature is slightly changed or incorrect, human vision can immediately feel the color change on the screen, so the camera is taken. Getting the precise color temperature value of the scene is one of the most important tasks in the success or failure of the work.

However, the external white balance filter lens (7) and the white balance lens cover (6) are used for the manual white balance action, but the correct color temperature value and color of the shooting scene cannot be obtained, and the reason is derived from the external white balance filter lens (7). ), the overall design of the lens cover is poor, when facing the camera scene, all the light and color outside the camera are not selectively projected on the filter lens and combined into an incorrect average color temperature value.

Each color on a substantial object has its own unique color temperature value under each light source, and each time the direction is rotated, the composition of the image composition includes a different color ratio, and the average color temperature value of each imaging composition is different. They are also different, so only the range of camera composition can get the most accurate white balance average value.

Taking the outdoor as an example, the framing of the camera (2) is based on the angle of view and the distance of the focal length of the lens (21), and the composition of the framing is often ranged, but the flat white balance filter lens (7), white balance lens cover (6) receiving unnecessary light outside the range of the image composition, such as sunlight, sky, blue light, white light, reflected light on the white balance filter lens (7) or white balance lens cover (6) filter (61), On the white balance filter lens (7) or the white balance lens cover (6) filter (61) constitutes an incorrect average color temperature value of the incorrect composition range, let The camera (2) that performs the manual white balance calculation obtains an incorrect color temperature value within the imaging range to perform an imaging operation, and the color temperature and color expression of the photographs and movies that are photographed naturally have a color shift phenomenon.

In indoor photography, the indoor or outdoor main light source, ambient reflected light and color are projected from the white balance filter (7) or the white balance lens cover (6) filter (61) in all directions, via the white balance filter. The light transmission structure of the body (7) or the filter (61) of the white balance lens cover (6) enters the color temperature detection range, so that the manual white balance system measures the incorrect white balance average value, resulting in photo color Distortion phenomenon, in addition to general photography purposes, to obtain the exact color of the item, is very important in some scientific research, color management, typesetting printing or recording, such as obtaining the standard color of the item in different light source environments or places, for color comparison Correction to achieve consistency, therefore, how to obtain the correct white balance average value in a simple, fast and low cost is the main purpose of this creation.
