Abstract
A technique for applying a crosstalk filter to raw image sensor data in a digital image processing pipeline is disclosed. Raw image sensor data generated by an image sensor, where each pixel in the raw image sensor data includes an intensity value for only a single color channel of a plurality of possible color channels, is processed in the digital image processing pipeline. For each pixel of the raw image sensor data, a corrected intensity value is computed based on intensity values associated with one or more additional pixels of the raw image sensor data that neighbor the pixel.
