ABSTRACT:
A solid image pickup unit is provided which is capable of preventing the brightness of a reproduced screen from changing (a change in a storage time) due to hand shake correction and which is thus able to obtain a natural photographed image. An X-Y address-type solid image pickup unit having a hand shake correction function includes a reading vertical scanner for reading in sequence pixel information for each scanning line while performing vertical scanning and for determining the position of an image pickup area in the vertical direction within a photoreceiving surface on the basis of hand shake information, an electronic shutter scanner for resetting the pixel transistors in correspondence with the position of the image pickup area in the vertical direction when a predetermined storage time is reached whose upper limit is set to be shorter than the time corresponding one field, and a timing generator for supplying scanning clocks .phi.VCK and .phi.SCK and start pulses .phi.VS and .phi.SS to these scanners and for controlling the generation timing of the start pulses .phi.VS and .phi.SS on the basis of the hand shake information from an acceleration sensor.
