ABSTRACT:
A charge injection device image sensor, having increased sensitivity and dynamic range, utilizes a two-dimensional array of cells having m rows each with n cells arranged in n columns. A video preamplifier is connected to each associated column to amplify, in parallel, video signals from that one column, responsive to all of the n cells along a particular one of the m rows being simultaneously enabled. The rows are scanned in mutually-exclusive fashion. Each of the n amplified column signals is separately stored. The stored column signals are sequentially readout to provide the sensor video output signal.
