像素阵列、图像传感器及补偿全局和局部暗电流的方法
摘要：
提供一种像素阵列、图像传感器及补偿局部暗电流的方法。提供一种用于图像传感器的像素阵列。所述像素阵列包括暗像素，该暗像素被构造为检测有源像素块中的局部暗电流。所述暗像素与光学黑色像素块不同，其中，所述光学黑色像素块被布置在有源像素块周围并被构造为检测全局暗电流。所述像素阵列被构造为补偿暗阴影，其中，所述暗阴影不通过使用从布置在有源像素块内的暗像素输出的局部暗电流的全局暗电流补偿进行补偿。
摘要（英）：

A pixel array for an image sensor is provided. The pixel array includes a dark pixel which is configured to detect a local dark current in an active pixel block. The dark pixel is distinguished from an optical black pixel block which is arranged around the active pixel block and is configured to detect a global dark current. The pixel array is configured to compensate for dark shading, which is not compensated through global dark current compensation, using the local dark current output from the dark pixel which is arranged within the active pixel block.
