Abstract
PURPOSE: To detect a color split due to a camera shake by comparing the same color image signals of different frames with each other and deciding a motion picture or still picture.
CONSTITUTION: A color image signal which is gated by a gate circuit 2 at an optional position, e.g. center part of a screen is converted by an A/D converter 3 into a digital value and a CPU 4 compares the digital value. When the digital value is equal, it is decided that it is in a normal state wherein there is neither the motion of an object nor a camera shake and a normal still picture is obtained. When the digital value is not equal, on the other hand, it is a state wherein the object is in motion or the camera is shaken and a motion picture is decided to warn a color split by turning on a lamp 5. Consequently, valuable image data are never spoiled owing to careless camera operation, shaking, etc., and the normal color still picture is obtained.
