Abstract

Various technologies described herein pertain to defect pixel correction for image data collected by a pixel array of an image sensor. Neighborhood statistics for a given pixel from the image data are computed based on values of neighbor pixels of the given pixel from the image data. Whether the value of the given pixel is defective is detected based on the neighborhood statistics. The value of the given pixel is replaced when detected to be defective to output modified image data. Correction of the given pixel is a function of whether the given pixel is in a flat region or a non-flat region. When the given pixel is defective and in a non-flat region, a minimum edge across the given pixel is identified and the value of the given pixel is replaced with an average of values of neighbor pixels that belong to the minimum edge.
