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.
