The exposure calculation device for camera comprises a first photometric means which performs photometry on the photographic field divided into a plurality of regions and a second photometric means for which by comparison with the first photometric means the separation number is lower and which excels at low luminance photometric performance, and a calculation means which calculates an exposure value in a comparatively high luminance situation by dominantly using the output of the first photometric means and in a comparatively low illumination situation by dominantly using the output of the second photometric means; and it is possible to obtain an accurate exposure value, even in a special environment such as a high temperature situation or low luminance or the like.
