Patent ID: 7995125

Claim:
An image sensor integrated circuit comprising: an array of pixel circuits arranged in columns and rows, each pixel circuit comprising: a first charge storage element electrically connected across an amplifier and configured to store charge in response to light detected by said each pixel circuit; a second charge storage element; and first and second gain select switches configured to selectively connect the second charge storage element in electrical parallel with said first charge storage element, and thereby allow said second charge storage element to also store charge in response to light detected by said each pixel circuit; a first plurality of gain control column lines, each of said first plurality of gain control column lines configured to simultaneously control a plurality of said first gain select switches belonging to pixel circuits in an associated column of the array; and a second plurality of gain control row lines, each of said second plurality of gain control row lines configured to simultaneously control a plurality of said second gain select switches belonging to pixel circuits in an associated row of the array.
