Abstract
The utility model relates to an automatic white balance adjusting system which can automatically correct white balance and improve the work efficiency. The automatic white balance adjusting system comprises a color analyzer and a white balance correction controller, wherein the data output end of the color analyzer is connected with the data input end of the white balance correction controller through a serial communication interface; the control signal output end of the white balance correction controller is connected with the control signal input end of a video processing chip in a monitor or a display through the serial communication interface. The automatic white balance automatically corrects the white balance through the white balance correction controller, thereby saving time and labor and improving the work efficiency.
Description
Technical field
The utility model relates to a kind of automatic adjustment white balance system.
Background technology
In exploitation new product TV or monitor, need carry out the correction work of white balance.Present white balance correction uses color analysis instrument CA210 manual correction usually, very wastes time and energy inefficiency.
The utility model content
The utility model is in order to overcome weak point of the prior art, to provide a kind of and can make white balance correction work realize automation mechanized operation, the automatic adjustment white balance system of increasing work efficiency.
The utility model is achieved through the following technical solutions:
A kind of automatic adjustment white balance system, it is characterized in that, comprise color analysis instrument, white balance correction controller, the data output end of described color analysis instrument is connected by the data input pin of serial communication interface with the white balance correction controller, and the control signal output ends of described white balance correction controller is connected with the signal input end of video frequency processing chip in monitor or the display by serial communication interface.
The utlity model has following technique effect:
Automatic adjustment white balance system of the present utility model carries out correction work by the control of white balance correction controller, has realized automation mechanized operation, and is time saving and energy saving, improved operating efficiency.
Description of drawings
Fig. 1 adjusts the schematic diagram of white balance system automatically for the utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in detail.
The schematic diagram that the utility model is adjusted white balance system automatically as shown in Figure 1, comprise color analysis instrument, white balance correction controller, the data output end of described color analysis instrument is connected by the data input pin of serial communication interface with the white balance correction controller, and the control signal output ends of described white balance correction controller is connected with the signal input end of video frequency processing chip in monitor or the display by serial communication interface.Wherein, the white balance correction controller can adopt PC, single-chip microcomputer etc.
The value of the default chromaticity coordinate that need reach in color analysis instrument is by the probe test monitor of color analysis instrument or the actual value of display.The value of the chromaticity coordinate that default needs reach and the actual value of test are delivered in the white balance correction controller and are compared, if it is variant, the white balance correction controller is then by serial communication interface output control signal, adjust red/blue gain in monitor or the display program and the numerical value of setovering, so repeatedly, the actual value up to test reaches consistent with default value.
