Patent ID: 6963367

Claim:
An image pickup apparatus comprising: a plurality of pixels each including a photoelectric conversion portion which converts an optical signal from an object into an electrical signal and a read portion which reads out the signal from said photoelectric conversion portion to an output line; a drive control portion which controls a first mode for reading out from said read portion a pixel noise signal which is obtained by resetting an input portion of said read portion, and a second mode for reading out from said read portion an image signal which includes a signal generated by said photoelectric conversion portion; a correction portion which subjects the image signal read out from said read portion, to correction processing which uses the pixel noise signal; a detection portion which detects an object condition; and a switching portion which switches over the correction processing of said correction portion in accordance with an output of said detection portion; wherein said detection portion detects that a signal level of the pixel noise signal is higher than a predetermined value.
