发明名称 Camera and wide-angle field distance-measuring camera
摘要 A camera includes a sensor array which can detect a brightness signal of a subject and has a plurality of segments for focal point detection, a first photometry unit for calculating the brightness signal of the subject on the basis of an output of one segment or outputs of the segments of the sensor array, a second photometry unit which can detect a brightness signal of the subject in a detection range wider than that for the detection of the subject brightness signal by the sensor array, and a determination unit for determining on the basis of an output of the second photometry unit whether the use of the first photometry unit is forbidden. The camera can determine backlight without any inconvenience even on photographing condition close to the very limit of a photometrical range.
