Title: Autofocusing device and storage medium storing control procedure for the autofocusing device
Inventor: OCHIAI TORU
IPC: H04N1/04
Filed: 1998-04-22
Abstract: PROBLEM TO BE SOLVED: To allow the device to accurately confirm focused position by discriminating it that there is no large change in contrast when each detected contrast value is within a prescribed range. SOLUTION: A scanning block is placed at a prescribed position P1 on an original. Contrast at a focal position is detected at three positions, that is, the prescribed position P1 and positions apart from the prescribed position P1 by very small distances ±A. When the obtained contrast value is within a proper range, the automatic focusing operation is executed at the prescribed position P1 and when the obtained contrast value is not within a proper range, a lighted color of a light source is changed from red to green. In the case that the obtained contrast value is not within a proper range even when any of the red, green and blue lighted colors is selected, since it is only discriminated that the contrast is not within a proper range as to the red lighted color, similar processing is conducted as to the green lighted color.  Thus, when the contrast value is within a prescribed range, it is discriminated that there is no large contrast change in a pattern.
