<p>PURPOSE:To execute display corresponding to each function, by calculating a set aperture value signal and a film speed signal, providing decoders of the aperture value signal, the film speed signal and the operation signal, and executing each display. CONSTITUTION:An aperture setting part 1 sets an aperture value corresponding to an aperture value of a camera, and outputs a signal of a binary number in accordance with a set aperture value. A film speed setting part 2 sets an ASA speed of a film to be used, and outputs a signal of a binary number corresponding to the set ASA speed. Outputs of the setting parts 1, 2 are calculated by considering brightness of an auto electronic flash by an operating part 3. Subsequently, the outputs of the setting parts 1, 2 and the operating part 3 are applied to a programmable read-only memory P-ROM 7 through decoders 4-6, respectively. Outputs of the ROM 7 are sent to a display parts 8-10, and an aperture value corresponding to the set aperture, an ASA speed corresponding to the set ASA, and a range are displayed.</p> |
