Mark, you can with the M (M1, M2, M3, M4) to be obtained in step S430, by the value of cmdID, i.e. local alignment command id
Value, determines to need the event for carrying out color calibration, and then issues the instruction that screen color calibration is carried out to display unit.Based on bag
The data volume that the network sending module agreement of the structure of regional area coordinate to be calibrated is included when reducing transmission, because each base
Color only gathers an image and carries out regional area extraction, and the view data of acquisition also only has an image, without each from 0-255
Color all gathers, because each color calibration speed is significantly slower.On the other hand, should the network sending module based on structure
Agreement only has 24 bytes, and than sending an image, once several million occupancy resource spaces are small.And then it can realize so that showing single
Member need to can only improve calibration efficiency, prevent network congestion from showing to specifically needing the regional area calibrated to calibrate
As.
Step S440:Each primary colours of display unit for locally needing to adjust are calibrated from 0-255.
Specifically, to each pixel in the different base colors image of each display unit from 0-255 grayscale with it is corresponding
Default gray value is compared, and obtains each color calibration value.Network based on the structure including area coordinate to be calibrated is sent
Module protocol, which is sent, includes the area coordinate to be calibrated that needs are calibrated, and the corresponding color calibration value of area coordinate to be calibrated
Calibration command makes display unit be calibrated according to calibration command to display unit.
Step S450:Complete color local alignment.
The screen color part quick calibration method that the present invention is implemented from color calibration controller angle, in display unit
Screen color local alignment process can preserve each some RGB color value image of primary colours according to collection is actually needed, and committed memory is empty
Between it is smaller.And some specific region for needing to calibrate in display unit need to be only calibrated, without calibrating whole display unit, is improved
Calibration speed.Further, network sending module agreement is optimized by the less local alignment structure of byte number, can
Effectively reduce network congestion.
