System design of camera for coded exposure

Based on the theory of coded exposure, an applied embedded coded exposure camera system was designed. The exposure shutter of camera was controlled according to the preset coding sequence when collecting the moving target image, and the image of photo-generated charge multiple superimposed with a transfer was obtained. The acquired image was a motion blurred image with coded exposure information, which had more details of the target. The data was temporarily stored in the data memory by the coded exposure image after the AD conversion, and the restored image was decoded by the core device. The experimental results show that the coded exposure camera can effectively solve the problem of linear motion blur. In the same conditions, the index average value of restored image quality under coded exposure condition is increased nearly twice than that of restored image quality under single exposure condition by using the no-reference image evaluation index test.
