Image pickup apparatus
First Claim
1. An image recording system comprising:
- (a) a photosensing part for converting an optical image into an electrical signal;
(b) combining means for combining a part of the electrical signal converted by said photosensing part with a signal opposite in polarity to said electrical signal, said combining means having at least two operation modes;
(c) recording means for recording a signal representing a still picture in response to said electrical signal converted by said photosensing part;
(d) trigger means for allowing said recording means to selectively record a signal representing a still picture; and
(e) control means for controlling said combining means in response to an output of said trigger means.

Abstract
An image pickup apparatus comprises: an image sensor for converting an optical image into distribution information of a minority carrier; a control circuit for periodically forming a first state in that a majority carrier is accumulated in the image sensor and a second state in that at least a part of the minority carrier is recombined with this majority carrier; a readout circuit for reading out the information in the image sensor; a recording apparatus for selectively recording the information for a predetermined interval from the information to be read out by the readout circuit with regard to the trigger operation for a still photograph; and a stopping circuit for stopping the control operation of the control circuit in association with the start of the recording by the recording apparatus or the closing of a shutter or in response to a low luminous condition or the like.
