Abstract

According to the characteristics of space camera subject to working environment and task requirements, the automatic exposure and automatic white balance are analyzed theoretically. Gaussian weight is used to correlate the target position and gray value of image, and the relationship between variable step size adjustment, balance accuracy and speed of automatic exposure is optimized. Automatic white balance performs color temperature estimation in RGB space, enabling accurate image color restoration under different illumination. The optimized design of hardware implementation according to the FPGA characteristics. Through the simulation software analysis and the effect of the hardware system display pictures, it is shown that the FPGA hardware system can run high-definition real-time, fast speed, low power consumption and strong practicability. This hardware system has been used in image processing of space cameras.
