A device includes a photometry element for photometrically measuring object light while dividing the object light into a plurality of color components, and an exposure controller for calculating an exposure control value on the basis of a plurality of photometry outputs corresponding to the color components from the photometry element. In the device, the photometry element divides object light into a plurality of color components, e.g., R, G, and B three primary colors, and performs level detection in units of color components. The exposure controller preferably determines, as an exposure control value, a color component of a maximum level of the photometry outputs corresponding to the color components which are measured by the photometry element. Exposure control is executed by calculating an aperture value, a shutter speed, and the like on the basis of the determined exposure control value.
