Claims (1)

[Scope of Claim for Utility Model Registration] An exposure value is calculated by calculating the brightness value of the subject detected by the photometer and the film sensitivity value by the exposure value calculation means, and the exposure-related members are adjusted based on the exposure value. In a camera that is configured to obtain proper exposure using the photometer, when the luminance value measured by the photometric means is a low luminance value at the lower limit of the photometric range, the measured luminance value is calculated from this value. 1. An exposure control device for a camera, characterized in that a correction means for correcting to a lower value is provided, and the exposure value calculation means calculates an exposure value based on the brightness value.
