ABSTRACT:
The disclosure is a solid-state imaging device, including a photosensor for collecting charge created by incident photons, a comparator for comparing a digital voltage value corresponding to the collected charge, to a predetermined value, and generating a comparison output, and a normalizing circuit for normalizing the digital voltage value, in response to the comparison output.
