Abstract
An electronic scope including a solid-state image pickup device arranged at a distal end of an endoscope and having an image pickup area whose aspect ratio is 1:1, an image processing circuit for masking the image signal output from the image pickup device, and a display device having a screen whose aspect ratio is 3:4. The image processing circuit has frame memories for storing one-frame image signals, a mask signal generator for generating a mask pattern signal, and a gate for permitting/inhibiting supply of the image signal from the frame memories to the display device in response to the mask pattern signal from the mask signal generator.
