摘要:
An exposure control device for a camera is so structured that the film information recorded on the film or the cartridge is read, the reflection coefficient of the loaded film is determined based on the read film information and the termination of light emission of an electronic flash device or the start of run of a shutter curtain is controlled in accordance with the reflection coefficient so that the proper exposure is always obtained by the light emission control or the shutter control by the TTL direct light detection irrespective of the change of the reflection coefficient of the film.
