Exposure control apparatus for electronic development type camera

摘要

An exposure control apparatus for an electronic development type camera having a photographic optical system. The camera uses a recording medium in which subject images formed through the photographic optical system are electrically developed. The exposure control apparatus includes a detecting device for detecting first photometric data which corresponds to subject light passed through the recording medium at a moment an exposure of the recording medium commences. The detecting device further detects second photometric data which corresponds to subject light passed through the recording medium after the exposure commences and before the exposure terminates. The exposure control apparatus further includes a calculating device for calculating a transmittance of the recording medium after the exposure commences, using the first and second photometric data, and a controlling device for controlling the exposure of the recording medium in accordance with the calculated transmittance.
