Embodiment Construction
[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0022] like figure 1 As shown, the projection light machine automatically configures the system for optimizing the white balance, including smart devices, illuminance meters, and light machines. The smart devices are connected to the illuminance meter and the light electromechanical, and the smart devices are generally computers. Connect the smart device and the illuminance meter with a USB-TYPE B line. The illuminance meter needs to be able to measure the data of color temperature Tcp, chromaticity x and chromaticity y. In the present invention, Konica Minolta CL-200A is preferably used for data measurement . The smart device and the optical machine are connected sequentially with the first serial port, TX / RX crossover, GNG connection and the second serial port. Among them, the first serial port and the second serial port are preferably pl2303 serial ports...

The invention discloses a system and a method for automatically configuring optimal white balance by a projection optical machine. The system comprises intelligent equipment, an illuminometer and an optical machine, wherein the intelligent equipment is independently electrically connected with the illuminometer and the optical machine, the intelligent equipment has a white balance testing programto automatically test the color temperatures, the chromaticity x and the chromaticity y of all LOOK in the optical machine, qualified LOOK is selected, and a difference value of the color temperatureTcp of the qualified LOOK and an ideal color temperature is compared to select the optimal LOOK. The system has the advantages that: in the system for automatically configuring the optimal white balance by the projection optical machine, the testing of the color temperature Tcp, the chromaticity x and the chromaticity y of each group of LOOK in the optical machine can be automatically carried out,the qualified LOOK can be screened, the optimal LOOK is selected, human intervention generated when the optimal white balance is configured is reduced, and a selection process is simplified.
Description
technical field [0001] The invention relates to the field of projection technology, in particular to a system and method for automatically configuring and optimizing white balance of a projection light machine. Background technique [0002] White balance is color balance, which means that the correct color can be obtained on a specific display device by changing the color value of the image. Due to the inconsistency of the optical machine, the white balance of different optical machines is inconsistent. In order to solve this problem, the control chip of the optical machine will preset multiple groups of different configurations, referred to as LOOK, switch between different LOOKs, cause changes in white balance, find the optimal group and record it, and turn on the optical machine every time After that, the optical-mechanical control chip can set the corresponding LOOK. In the prior art, the relevant value of white balance is generally measured by an illuminance meter, an...
