Ladungsinjektionseinrichtungssensor

摘要

A charge injection device image sensor, having increased sensitivity and dynamic range, utilizes a two-dimensional array of cells (11) having m rows (R) each with n cells arranged in n columns (C). A video preamplifier (14) 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 (20). The stored column signals are sequentially read out to provide (at 10d) the sensor video output signal.
