ABSTRACT:
An image apparatus and method is disclosed for extending the dynamic range of an image sensor. A first linear pixel circuit produces a first pixel output signal based on charge integration by a first photo-conversion device over a first integration period. A second linear pixel circuit produces a second pixel output signal based on charge integration by a second photo-conversion device over a second integration period, where the second integration period is shorter than the first integration period. A sample-and-hold circuit captures signals representing the first and second pixel output signals.
