Abstract:
1. An imaging system configured to generate a corrected sensor value associated with a defective pixel of an image sensor based on a plurality of sensor values selected from a group of sensor values associated with pixels spatially positioned in at least two dimensions on the image sensor, the imaging system comprising: a buffer for receiving sensor values, each sensor value associated with a pixel in the image sensor, at least one of the sensor values being associated with the defective pixel; electronics for selecting sensor values associated with a pair of opposing pixels from among a group of sensor values, the group of sensor values being associated with pixels spatially positioned in at least two dimensions on the image sensor, the pair of opposing pixels being positioned within two pixels of the defective pixel and on opposing sides of the defective pixel, and wherein the pair of opposing pixels are the same color as the defective pixel; and electronics for generating the corrected sensor value to be associated with the defective pixel, the corrected sensor value being a function of the sensor values associated with the opposing pair of pixels.
