Abstract
An image sensor with a pixel array that has two or more pixels is discussed. The defective pixel detector detects a defective pixel. A dynamic threshold range is based on amplitude levels of neighboring pixels. The defective pixel detector detects the defective pixel with the dynamic threshold range to detect and determine a defective status for the pixel under analysis based on an amplitude level of the pixel under analysis relative to the amplitude levels of neighboring pixels. The defective pixel detector applies algorithms to create candidate pixel patterns for the neighboring pixels used to create the dynamic threshold range. The value of the dynamic threshold range will change based on the amplitude levels of the neighboring pixels.
