Color acquisition method and device

Abstract

The present invention provides a color collection method and device. The method includes the following steps: collecting first color components of three colors of RGB at the current moment; judging whether the collected voltage value of the first color component is greater than a preset threshold; No, then disconnect the collection of the second color component and the third color component of the RGB three colors, and continue to collect the first color component when the next first color component collection time is detected, until the accumulated first color The voltage value of the component is greater than the preset threshold. The color acquisition method and device of the present invention solve the problem of a small voltage value caused by the short on-time and integration time of the control signal, are not restricted by the short duration of the control signal, and can systematically control multiple The integration time of the time is accumulated to improve the value of the R, G, and B collected voltage signals, ensuring that stable and reliable collected data can be obtained, and greatly improving the collection accuracy and stability.

Description

technical field [0001] The invention relates to the field of video applications, in particular to a color collection method and a color collection device. Background technique [0002] At present, the field of video application is very extensive, and the color acquisition and adjustment related to video application is one of the key technologies. Usually, the system is excited by the video signal and then through the display device (such as optical machine, projector, etc.) to restore the image color realistically. , which can be intuitively captured by the human eye. Image color generally includes three elements: brightness, hue, and saturation. Video equipment also needs to adjust image color to make it the most comfortable and clear state for human eyes. Video equipment adjusts the image color by adjusting the current value of its LED (Light Emitting Diode, light-emitting diode) lamp or bulb. This is used as a feedback signal to be transmitted to the controller to adjus...

AI Technical Summary

Problems solved by technology

However, the problem with the traditional color acquisition method is that the current signal converted by the photoelectric sensor sensor is very weak, and the control signal (STROBE_R, STROBE_G, STROBE_B) of some systems lasts for a very short time, that is, the integration time for converting current into voltage It is very short, so it is very unfavorable to signal acquisition. There is no discrimination when the current is small, and there is a little interference fluctuation, the collected value will change a lot, and the accuracy and stability are low.
