Abstract:
An image sensor apparatus comprises an image sensor for generating digital images having a high dynamic range. The image sensor apparatus includes an image sensor for generating a first and a second set of digital image samples at a first bit depth, with each set of digital image samples generated by a different column readout circuit path. A processor combines the first and second set of digital image samples to generate a digital image at a second bit depth, the second bit depth higher than the first bit depth.
