| 摘要 | PURPOSE:To set photographic information easily and accurately by adding a specified value to calculated photographic information and comparing the sum with set information, and then subtracting a specified value according to the comparison result. CONSTITUTION:Once aperture-priority automatic exposure mode, etc., is selected, a CPV362 calculate a shutter speed TV corresponding to photometric information from an input controlling part 360. Then, the CPV 362 adds a specified permissible value K1 to the speed TV and then subtracts a set shutter speed TV' set by the dial of a camera mechanism part 38; when a carry is generated, it is displayed in a viewfinder, warning that the speed TV' is improper. When this set value TV' is less than the permissible value, the specified permissible value K2 based upon equationIis subtracted from the subtraction result; when a carry is generated, a decision on that the set value TV' is within permissible ranges of +K1 and -(K2-K1) is made and when not, an increase in the stop- down extent of the mechanism part 38 or an increase in shutter speed set value is indicated. Even in shutter-speed priority automatic exposure mode, accurate set value adjustment of even brightness is made similarly and easily. | ||
