An electronic image pickup apparatus picks up an object image such as an image on a blackboard and outputs the image. The apparatus can synthesize a picked-up image with format data input from another unit and output the synthesized image. When synthesis processing is to be performed, format data to be synthesized are created and stored in several line buffers in advance. When a picked-up one-line image signal is written in a line buffer of 1 line, the format data stored in the several line buffers are read out, and the image signal and the format data are synthesized in the line buffer of 1 line. By outputting the data in this line buffer in units of lines, the synthesized data obtained by synthesizing the picked-up image with the format data is output. A movable focus screen and a movable mirror are provided, along with a driving device for moving the focus screen and the mirror, in order to eliminate the need for a separate shutter plate, thus enabling miniaturization of the electronic image pickup apparatus.

An image pickup apparatus includes an optical system for forming an image of an object. An image pickup section effects the image pickup operation by causing a one-dimensional image pickup device to scan an image formed by the optical system. A light exposure detecting section detects light exposure based on a luminance signal output according to the scanning operation of the one-dimensional image pickup device at the light exposure detection time. A control section controls the image pickup section according to the light exposure detected by the light exposure detecting section at the time of image pickup operation.
