Abstract
A photosensitive pixel includes a photosensor and an externally loadable flag. The photosensor outputs a signal indicative of an intensity of incident light. The externally loadable flag indicates the pixel reset state, and is preferably stored in an in-pixel memory. Pixel reset logic resets the photosensor in accordance with the reset state and an externally applied reset signal.
