Abstract
A controlling method for a CCD camera in which a photographing area is divided into a number of cell regions, the illumination of each cell regions is detected the photographing mode of a camera is switched to a daytime or nighttime mode on the basis of the detected illumination so that an optimum image is photographed even under conditions where the illumination of a certain position and the total illumination condition in the photographing place changes irregularly.

15. A method of controlling a photographing mode of a camera, comprising the steps of:
-
dividing a photographing area into a plurality of cell regions and detecting an illumination level of each cell region;
determining whether the detected illumination level of each cell region is greater than the previously determined standard illumination level;
counting the number of the cell regions having a lower illumination level than the standard illumination level;
determining whether the counted number is greater than a certain percentage of the total number of cell regions; and
switching the photographing mode of the camera on the basis of the determination. - View Dependent Claims (16, 17, 18)
