Abstract
A method for determining a deblurred image from images captured using an image sensor comprising a two-dimensional array of light-sensitive pixels including panchromatic pixels and color pixels, the method comprising: receiving image sensor data from the image sensor for a sharp image of a scene captured with a short exposure time; receiving image sensor data from the image sensor for a blurred image of the scene captured with a longer exposure time than the sharp image; determining an interpolated sharp grayscale image from the sharp image; determining an interpolated blurred color image from the blurred image; determining an interpolated blurred grayscale image from the blurred image; determining a blur kernel responsive to the sharp grayscale image and the blurred grayscale image; determining a deblurred image responsive to the blurred color image and the blur kernel; and storing the deblurred image in a processor-accessible memory system.
