Abstract

In order to satisfy the requests of the high frame rate and high resolution of fast moving scene in national defense

research and industry

a camera with high-speed and high resolution was developed. The functions and characteristics of CMOS image sensor AM41V4 which can cover the requests were introduced

a camera system based on the image sensor was designed. The FPGA was used as the core to control the system timing and DDR solid storage was embedded as the imaging memory in the camera system. Consequently

a flexible working pattern according to specific requirements of the test shoot occasions was realized. The frame rate of the system is 1 000 frames per second

when the resolution of the image is 1 920 pixel1 080 pixel. Besides

the camera system reaches a real-time monitoring function. The system has the advantages of high shooting speed

clear image

high performance and flexibility. It has great value for fast capture and shooting record of high-speed moving targets.
