Abstract
A method for producing a digital image from pixel signals captured by an image sensor array is disclosed. The method includes: providing an image sensor array having at least two groups of pixels wherein the pixels of each group are uniformly distributed over the sensor; exposing the image sensor array to scene light and reading pixel charge from only the first group of pixels to produce a first set of pixel signals; after producing the first set of pixel signals, exposing the image sensor array, and then reading pixel charge from the second group of pixels and reading again pixels from the first group to produce a second set of pixel signals; and using the first and second sets of pixel signals to produce the digital image.
