ABSTRACT:
The object of this invention is to increase the precision of an exposure value in a scan AE scheme. To achieve this object, an image is picked at a plurality of exposure values. Screen-split brightness values and exposure value differences are obtained for the respective exposure values. Two screen-split brightness values and exposure value differences are selected from the relationship between the exposure value differences. A brightness value is calculated from the selected values to decide an exposure value in actual exposure.
