ABSTRACT:
An image pickup device comprises a photoelectric conversion device for converting an optical image focused on an image pickup area into an electrical signal, a monitor for displaying the optical image on a monitor image frame, a visual axis detection device for detecting the visual axis of the operator's eye on the monitor image frame, a discrimination circuit for discriminating whether the detected visual axis is present inside a predetermined area on the monitor image frame, a detection area setting circuit for setting a detection area for extracting predetermined control information in the image pickup area and a control circuit for controlling the detection area setting circuit based on the output of the discrimination circuit. The control circuit sets the detection area as an area including the visual axis in case the discrimination circuit discriminates that the visual axis is positioned inside the predetermined area and sets the detection area as a predetermined fixed area in case the visual axis is discriminated to be outside the predetermined area.
