Abstract

At present

a lot of deep space exploration use CCD as high resolution camera sensor. Compared with CCD image sensor

area array CMOS has advantages of simple drive

low power consumption

and high radiation tolerance. CMOS is currently the trend of the development of deep space remote sensing detection. Therefore

a large area array CMOS high resolution camera was designed and implemented

using CMOS image sensor CMV20000 produced by CMOSIS company

the image resolution is 5 1203 840. The overall structure of the FPGA as the core of the electronics system was described. Combined with CMV20000 operation mode and sequential circuits

the high speed transmission of high resolution images and data correction were realized. Experimental results show that the design of camera system is reasonable

the problem that the CMV20000 data cannot be aligned was solved. The operation of the system is stable and reliable

the high quality images can be acquired after installing the optical system.
