ABSTRACT:
An image pickup device comprises illuminating means for illuminating an object and an image pickup element for picking up an image of the object. An improvement is in that a drive circuit for driving the illuminating means and a control circuit for controlling the driving of the image pickup device are integrated with the image pickup device into one chip, in order to operate the image pickup device only a single power source and to minimize the device structure.
