Still image output of a typical retina-like CMOS sensor is simulated firstly according to the arrangement of imaging device array, which is important for following research on imaging theory of the sensor in high speed forward motion. Then, the degeneration matrix of the sensor in high speed forward motion is deduced on the basis of imaging mechanism of high speed forward motion and imaging characteristic of the sensor, and the retina-like CMOS sensor is qualitatively proved to exhibit less fuzzy degree compared with the rectangular sensor that has the same visual field and biggest resolution in transverse and longitudinal with the retina-like CMOS sensor, according to visual effect of simulated blurred images recorded from the two kinds of sensors. Finally, it is quantitatively proved that the retina-like CMOS sensor has great application potential in high speed forward motion with method to evaluate image quality based on structural information of the blurred image in polar coordinates.
