Title:
SOLID STATE IMAGE PICKUP DEVICE AND ITS VIDEO SIGNAL OUTPUT DEVICE
Document Type and Number:
Japanese Patent JP3875423
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To eliminate a state where every boundary of areas is conspicuous as a fixed pattern noise by outputting the partial images of areas adjacent to each other for every divided area.
SOLUTION: A solid state image pickup device with which the image signals are read out of the divided areas in parallel to each other is provided with plural horizontal and/or vertical scanning circuit which reads the image signals overlapping each other out of the vertical and/or horizontal line pixel string respectively. With such a constitution, the characteristics of signal reading circuits placed in every divided area are averaged by an averaging circuit. For instance, the horizontal scanning circuits 1-4 of a MOS amplification type solid state image pickup device are driven by the horizontal start pulses which start at the same time and the vertical scanning circuits 1 and 2 are also driven by the vertical start pulses which start at the same time. The image signals which are read by these horizontal and vertical scanning circuits are outputted from the reading circuits 1-4 simultaneously with and in parallel to each other.
