ABSTRACT:
An image pickup apparatus which is capable of full line reading, comprises a line delay device, a picture element delay device, a switching device, and an adding device. The line delay device delays an output of an image pickup element for one line. The picture element delay device delays the output delayed for one line for one picture element. The switching device selects the output either of the line delay device or of the picture element delay device and outputs the selected output. Furthermore, the switching device is adapted to supply the selected output for the adding device at every two lines in a cycle of four lines. The adding device adds the output of the switching device to the output of the image pickup element and outputs the added output.
