AB - Based on the working environment and characteristics of EBAPS cameras, a theoretical analysis is conducted on the relationship between camera exposure time, bias voltage, and image brightness information. An adaptive control method based on histogram feature function is proposed and implemented in the camera. Firstly, multi-point metering is used to extract regions of interest, and variable exposure time adjustment steps and bias voltage adjustment steps are designed to reduce the system metering calculation while improving the convergence speed and stability of EBAPS camera adaptive adjustment. The experimental results show that when the light intensity varies within the range of 10-4Lux to 100 Lux, the EBAPS camera can automatically adjust two parameters included bias voltage and exposure time, to stabilize the brightness of the output image, improve the image information entropy and the dynamic range of the camera. This method can also provide reference for subsequent image recognition and target tracking.
