ABSTRACT:
A charge-coupled device image sensor comprises a matrix array of photodiodes and a horizontal charge-coupled device (CCD). First vertical CCDs are provided, each on one side of each column of the photodiodes for receiving charge packets from the photodiodes of odd-numbered rows and moving the charge packets to the horizontal CCD and second vertical CCDs are provided, each on the other side of each column of the photodiodes for receiving charge packets from the photodiodes of even-numbered rows and moving the charge packets to the horizontal CCD. The horizontal CCD receives the charge packets from the first and second vertical CCDs and transfers the received charge packets to external circuitry. According to a modified embodiment, a second horizontal CCD is provided for receiving the charge packets from the second vertical CCDs.
