ABSTRACT:
A method of producing a low resolution image from a sparsely sampled extended dynamic range digital image, including the steps of: providing a sparsely sampled extended dynamic range image sensing device having fast photosites with a predetermined response to light exposure interspersed with slow photosites with a slower response to the same light exposure; using the image sensor to produce a sparsely sampled high resolution digital image having fast pixel values produced by the fast photosites and slow pixel values produced by the slow photosites; and constructing a low resolution digital image from the sparsely sampled high resolution digital image by using only slow pixel values or only fast pixel values from the sparsely sampled high resolution digital image.
