Real-Time Non-Uniformity Correction Algorithm for CMOS Image Sensor

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.
