Abstract
The utility model discloses a system for white balance correction by using a color plate. The system comprises a light source and a shooting device, further comprises a color plate. The color plate consists of at least one color sub-plate, and different sub-plates have different colors; and the shooting device comprises a white balance correction device consisting of a color collection module, a color comparison module and a white balance parameter adjustment module. The system for white balance correction by using a color plate has the following technical effects: as the color plate is additionally provided, pictures have no color shift due to the variation of the light source, the quality of pictures and the shooting success rate are improved; as the demand for the repair and maintenance to the light source by the system are reduced, the management difficult is decreased; as the requirement on the light source by the system is lowered, the cost is therefore reduced.
Description
Technical field
The utility model relates to a kind of equipment of white balance correction, relates in particular to a kind of system that utilizes tint plate to carry out white balance correction.
Background technology
The basic conception of white balance is: no matter under any light source, white object can both be reduced to white.The image that human eye is seen was done color through brain and was handled, and the image of camera in order to see the image that photographed near the people need be done a colour correction according to light source.Colour cast to the image that collects at specific light source sensitive chip of following time occurs compensates by strengthening corresponding complementary color.Do not need white balance that the people participates in Automatic white balance.Because the diversity of light source, Automatic white balance can not be tackled all situations entirely truely.White balance correction system's meeting of the prior art is because the variation of light source cause the photograph of taking to produce colour cast.
Therefore, those skilled in the art is devoted to develop a kind of system of white balance correction to overcome above-mentioned defective.
The utility model content
Because the above-mentioned defective of prior art, technical problem to be solved in the utility model provides a kind of system that utilizes tint plate to carry out white balance correction, can be because the variation of light source cause the photograph generation colour cast taken to overcome white balance correction of the prior art system.
For achieving the above object, the utility model provides a kind of system that utilizes tint plate to carry out white balance correction, comprises light source and camera, also comprises tint plate, described tint plate is made up of at least one color daughter board, and every described color daughter board all has a kind of color inequality; Include the white balance correction device of being made up of color acquisition module, color contrast module and white balance parameter adjustment module in the described camera, described camera is relative with described tint plate.
Preferably, include redness, green and blue color daughter board in the described tint plate.
Preferably, the color daughter board that also includes white, black, orange, yellow, cyan, purple, grey, brown and indigo in the described tint plate.
Preferably, also comprise wall in the described system that utilizes tint plate to carry out white balance correction, described wall is positioned at the camera lens dead ahead of described camera.
Preferably, described camera is relative with described wall, and described camera is arranged on the carrier top.
Preferably, also has wallpaper on the described wall as photographic background.
Preferably, described wallpaper is blue.
Preferably, described tint plate is positioned on the described wall.
Preferably, described tint plate is positioned at the top of the described wallpaper of described wall.
Preferably, the imageing sensor that comprises CMOS or CCD in the described color acquisition module.
There is following technique effect in a kind of system that utilizes tint plate to carry out white balance correction that the utility model provides:
1. owing to set up tint plate, photograph can not produce colour cast owing to the variation of light source, has improved the quality of photograph and has taken success rate.
2. reduced the needs of system, reduced management difficulty the repair and maintenance of light source.
3. reduced the requirement of system, thereby reduced cost light source.
Be described further below with reference to the technique effect of accompanying drawing, to understand the purpose of this utility model, feature and effect fully design of the present utility model, concrete structure and generation.
Description of drawings
Fig. 1 is the pie graph that utilizes tint plate to carry out the system of white balance correction of the present utility model.
Embodiment
Embodiment 1:
As shown in Figure 1, according to a specific embodiment that utilizes the system that tint plate carries out white balance correction of the present utility model, comprise light source 10 and camera, camera is a video camera 40, and video camera 40 is arranged on carrier 60 tops.The system of white balance correction also comprises tint plate 20, and tint plate 20 is made up of at least one color daughter board, and every color daughter board all has a kind of color inequality.Include redness, green and blue color daughter board in the tint plate 20, also include the color daughter board of white, black, orange, yellow, cyan, purple, grey, brown and indigo.
Include the white balance correction device of forming by color acquisition module, color contrast module and white balance parameter adjustment module in the video camera 40, comprise cmos image sensor in the color acquisition module.Video camera 40 is relative with tint plate 20.
Use the automatic correcting camera color of autochromatic plate flow process:
1. before taking photograph, the cmos image sensor in the color acquisition module in the video camera 40 is at first gathered the image of tint plate 20.
2. by the color contrast module in the video camera 40 color data in the image that collects and known color data are compared, according to the result of its contrast, proofread and correct the color parameter relevant with white balance by the white balance parameter adjustment module in the video camera 40.Color parameter after the correction is only correct at current light source, if light source changes to some extent, then needs to proofread and correct again the above-mentioned color parameter relevant with white balance.
3. video camera 40 adopts this group color parameter to take photograph.
By the system that utilizes tint plate to carry out white balance correction of the present utility model, color parameter that will be relevant with white balance is after proofreading and correct under the light source that reality is used, take the photograph that comes out and can not produce colour cast, improved the quality of photograph and taken success rate owing to the variation of light source; Reduced the needs of system, reduced management difficulty the repair and maintenance of light source; Reduced the requirement of system, thereby reduced cost light source.
In other embodiments, the color acquisition module can also use ccd image sensor.
Embodiment 2:
As shown in Figure 1, the technical scheme of present embodiment and embodiment 1 is basic identical, and institute's difference is, utilizes tint plate to carry out also comprising wall 50 in the system of white balance correction, wall 50 is positioned at the camera lens dead ahead of video camera 40, and video camera 40 is relative with wall.Also have the wallpaper 30 as photographic background on the wall 50, wallpaper is blue.Tint plate is positioned on the wall, the top of the wallpaper of wall.
