ABSTRACT:
Pixel array including a high resolution mode and a low resolution mode and method of reading out the pixel array in a high and low resolution mode. The pixel array includes a first signal line and a second signal line. An array of pixel elements are provided, each pixel element coupled to the first signal line or the second signal line. A switch mechanism is provided for coupling the first signal line to the second signal line. A mechanism is also provided for conveying a charge associated with each pixel element to the first signal line or the second signal line. A mechanism may also be provided for buffering signals between the first signal line, the second signal line, and an output signal line.
