Image sensor

Image sensor can include: the pel array, it is including active pixel district that has the active pixel and the dark pixel region that has dark pixel, AD conversion unit, its configuration generatesdark pixel data code and generates the active pixel data code through the analog output who changes every active pixel for the analog output through changing every dark pixel, the skew extractor, itsconfiguration is for using dark pixel data code to draw final skew, and the corrector, its configuration is for using final skew to rectify the active pixel data code. The result is rectified in the conduct that the corrector was rectified in pixel data code and the identifying code according to the comparison output of active pixel data code and identifying code. It obtains through using final offset correction active pixel data code to rectify the pixel data code. 图像传感器可包括：像素阵列，其包括具有有源像素的有源像素区和具有暗像素的暗像素区；模数转换单元，其配置为通过转换每个暗像素的模拟输出来生成暗像素数据代码并通过转换每个有源像素的模拟输出来生成有源像素数据代码；偏移提取器，其配置为使用暗像素数据代码提取最终偏移；和校正器，其配置为使用最终偏移来校正有源像素数据代
