METHOD AND APPARATUS FOR DETECTING THE BAD PIXELS IN SENSOR ARRAY AND CONCEALING THE ERROR

摘要

A method of detection of bad pixel in sensor array and correction of detected bad pixels by inpainting and also to image sensor devices involving such sensor arrays adapted for identification and correction of the bad pixels. Importantly, image sensors which are provided to convert optical images to electrical signals would benefit from such possible detection and correction of pixel errors thereby providing for better quality of output. The method and the device enables providing for better quality cameras in particular digital cameras involving CCD image sensors or CMOS sensors. It monitors the health of the sensor arrays and increase its life, without involving any additional hardware cost. The invention targets all possible varieties of defective pixels including dead pixels, stuck pixels, hot and cold pixels and therefore is adapted to serve as a complete solution to such art of handling image corruption even for high numbers of bad pixels.
