PURPOSE:To perform high-precision digital display of photographic information with less error in reading while performing smooth photographing operation by converting a stage number with precision suitable for display an operated value by half adjusting. CONSTITUTION:To a half adjust circuit 998, bit digital photographic information having (1/4) precision obtained by arithmetic is inputted from an output bus line 366. Then, (1) is added to only a (1/4) stage precision bit and when the (1/4) stage precision bit of the input signal is (1), a carry signal is generated to made an end-around carry to a (1/2) stage precision bit. The photographic information with (1/2) stage precision suitable for display is obtained by the half adjust mentioned above is displayed after being stored in registers 684 and 650 for diaphragm value display and shutter speed display controlled according to the contents of the photographic information. Thus, smooth photographing operation is performed by the (1/4) stage precision bit information, and the digital photographic information is dipalyed by the (1/2) stage precision bit information with high precision without any error in reading because of no unnecessary confusion. |
