发明名称 Camera
摘要 A camera including a first and second luminance detector, a distance detector and a calculator. The first luminance detector, having a first spectral sensitivity and receiving light from a larger region of a photographing view, generates a first luminance information. The distance detector, having a second spectral sensitivity and receiving light from a smaller region of the photographing view, generates a distance information concerning a distance to an object. The second luminance detector generates a second luminance information based on the received light of the distance detector. The calculator calculates a control luminance value for exposure control based on the first luminance information and the second luminance information when the first luminance information is above a predetermined threshold value. In addition, the calculator calculates a control luminance value based on the first luminance information when the first luminance information is below the predetermined threshold value.
