| 摘 要： | 任何类型的图像传感器都存在着不可避免的非均匀性问题,非均匀性直接影响了传感器的成像质量及其应用范围.为此,讨论了多点校正方法的原理和算法,设计了基于复杂可编程逻辑器件(CPLD)的非均匀性校正实现方案,并针对CL512J型自扫描光电二极管阵列(SSPA)图像传感器进行了实时多点校正实验.结果表明,该校正系统能够将CL512J的非均匀性从40%降到2%.

| Abstract: | Because any type of image sensor has the inevitable question of nonuniformity which directly affect the quality of image and its using range, the paper discusses the principle and algorithm of multi-point nonuniformity correction and designs the scheme of nonuniformity correction based on Complex Programmable Logic Device (CPLD). The CL512J Self Scanned Photodiode Array(SSPA) image sensor is used in the nonuniformity realtime correction experiment. The result of experiment shows the correction system can reduce the nonuniformity of this image sensor from 40% to 2%. |
