  • To improve the Pixel Response Non-uniformity(PRNU) in a TDICCD mosaic camera, an algorithm was proposed to correct the PRNU between the channels and among the pixels in channels at different gains, deviations and integrated time. Then, a design method was given to implement the algorithm on a Field Programmable Gate Array(FPGA) platform. The experimental results indicate that the problems of PRNU could be solved at different gains, deviations and integrated time in the TDICCD mosaic camera. The PRNU of a single TDICCD could be decreased from 4.72% to 0.27%. In bad circumstance, the PRNU of the single TDICCD could be decreased from 4.68% to 2.13%. The actual image also proves that the pixel correction algorithm has high real time performance, high reliability and stability, and a satisfied result to the requirements of space-projects. It solves the real-time pixel correction problem of the PRNU in TDICCD mosaic cameras.
