Abstract

The principle and algorithm of two-point correction are discussed. And a non-uniformity correction systerm

whose hardware platform is FPGA

were designed. LUPA 300

was used in the system. Real-time non-uniformity correction was implemented in the system. The experimental result shows that system is effective to the real-time correction of the image sensor′s non-uniformity

and the system has a good image quality.
