[0050] The present invention will be further explained below in conjunction with the drawings and embodiments:
[0051] Such as Figure 4 As shown, the method for automatically adapting the CMOS image sensor to the external light environment according to the present invention enables the equipment using the CMOS sensor to automatically adapt to changes in the external environment; it does not require human intervention, and automatically changes in time according to the external environment. Adjustment; the correction speed is fast and the accuracy is high; the correction will not conflict with user operations, and will not affect the stability of the equipment. Specific steps are as follows:
[0052] Step 1: The system is powered on, the main controller initializes the CMOS, and sets the preset exposure parameters during initialization; if it has been calibrated before, use the exposure parameters saved during calibration;
[0053] Step 2: Collect a frame of empty original image an...
