Description

ABSTRACT:
The image readout apparatus has a plurality of independently driven image sensors. The charge storage time for each image sensor is determined based on light incident thereto, and the signal pickup is started in the storage completion order of the image sensor. The time sequential signal readout of each image sensor is sent to a single signal processor and thereafter it is stored in a memory. In the case of concurrent storage start of the image sensors, if the charge storage of an image sensor is terminated while the signal pickup of another image sensor is performed, the signal pickup of the former image sensor is temporarily delayed. To shorten the wait time for the signal pickup, the storage start time for each image sensor is shifted so as to realize a continuous signal pickup among the image sensors.
