CN203849532U - Sleeve direction-type white balance filter - Google Patents

Abstract

The utility model relates to a sleeve direction-type white balance filter comprising an outer sleeve body and a white balance element. The white balance element is arranged in the outer sleeve body and is capable of axial displacement adjustment. The outer sleeve body is made of a lightproof material, and can directly sleeve a lens or be assembled in front of the lens by means of a clamp tooth and a clamp groove in a sleeving manner. The white balance element is a milk-white or gray filter. A milk-white or gray extended annular edge part is formed on the periphery of the filter, and enables the white balance element to enter the outer sleeve body in a sleeving manner and to achieve axial displacement adjustment in the outer sleeve body. When the filter and the annular edge part are fully pushed in the outer sleeve body by the white balance element, the filter of the white balance element can only receive color light within a scene range observed through a window, so as to obtain an accurate white balance value.

Description

Sleeve directional type white balance filter

Technical field

The utility model relates to a kind of sleeve directional type white balance filter, espespecially a kind ofly comprise that an outer cylinder body and is located at and in outer cylinder body, can be the white balance element that axial displacement is adjusted, rely on and adjust the depth location of white balance element in outer cylinder body, and make white balance element only receive coloured light in scene domain to obtain accurate white balance numerical value, or receive the extraneous coloured light of scene (colour temperature) simultaneously, and then reach fine-tuning white balance element and receive the state of outside colour temperature, and then can obtain finely tuning main light source colour temperature ratio by means of fine adjustment function to meet the color temperature value of eye sense and individual vision hobby.

Background technology

The use-pattern of current flat white balance filter sheet 7 and the white balance lens cap 6 of tool filter 61, as shown in Figure 13, Figure 14 and Figure 15, facing to photography region, they to be placed on before video camera 2 camera lenses 21, carry out again manual white balance to trip, to ask for the white balance mean value of photographic scene, single color temperature value by this value as photography, to carry out camera work.

White is the basic of all colors, to be combined by red (Red), blue (Blue), green (Green), only in the time that three primary colours colour is mutually the same, R=B=G, white correctly could be shown to the vision the mankind, white is proofreaied and correct or is shown correctly, and other all colours of photograph, film could correctly be presented at people's vision.

The manual white balance object of video camera 2, in the average color temperature value that correctly obtains shooting scene, taking its as take colour temperature standard value by correct color representation on its works, can significantly reduce it at works with the incorrect color temperature value of software correction afterwards, because color and the photographic scene of the incorrect photograph of color temperature value, film are inconsistent, the high-accuracy vision system of the mankind can be distinguished difference wherein easily, and the incorrect shooting works of color representation are all failed works for all people.

Each width picture that photograph, film or live video transmit be all using single colour temperature as color according to the vision that shows the mankind, colour temperature slight change or when incorrect, human vision can be felt the variation of color on picture at once, so the accurate color temperature value that obtains photographed scene of making a video recording is one of most important work of works success or failure.

But utilize external white balance filter sheet 7, white balance lens cap 6 to carry out manual white balance action, but can not obtain the correct color temperature value of photographed scene and color, its reason come from the global design of external white balance filter sheet 7, lens cap bad due to, when in the face of shooting is when scene, all light outside video camera and color all have no selectivity and are incident upon on filter sheet and are combined into incorrect average color temperature value.

Each color on essence object has its unique color temperature value under each light source, and when its direction of every rotation of when shooting, the formation color-ratio that comprises scope of its shooting composition is different separately, and the average color temperature value of each shooting composition is also different separately, institute has for the scope of the composition of making a video recording and just can obtain the most accurate white balance mean values with Only.

Take open air as example, finding a view according to the visual angle of the focal length of camera lens 21 and distance of video camera 2, the shooting and composition is found a view, often to have its scope, but dull and stereotyped white balance filter sheet 7, white balance lens cap 6 but receives the unnecessary light beyond shooting composition scope, as sunlight, the reflection ray of sky blue light white clouds is on the filter 61 of white balance filter sheet 7 or white balance lens cap 6, and on the filter 61 of white balance filter sheet 7 or white balance lens cap 6, form the incorrect average color temperature value of incorrect composition scope, allow the video camera 2 of doing manual white balance computing obtain with its image pickup scope in the action of going to make a video recording of incorrect color temperature value, the photograph that it takes out, the colour temperature color representation of film has had color offset phenomenon naturally.

And in the time of pickup, indoor or outdoors main body light source, Ambient light and color are on being incident upon the filter 61 of white balance filter sheet 7 or white balance lens cap 6 from all directions, via the translucent construction of 61 somas of filter of white balance filter sheet 7 or white balance lens cap 6 and enter colour temperature sensing range, record incorrect white balance mean values so to manual white balance system, and cause the phenomenon of photograph color distortion, except general photography purposes, obtain the accurate color of article, in some scientific research, color management, typographical printing or record are very important, such as the lighting environment different or place obtain the Standard Colors of article, make color and relatively proofread and correct agreeing property, therefore, as how simple, fast and cost low to obtain correct white balance mean values be to be fundamental purpose of the present utility model.
