Patent ID: 6853806

Claim:
A camera comprising: a sensor array which detects an image signal of a subject existing in a specific position on a photographic screen and which includes a plurality of sensors; a computing section which calculates an average value of outputs of a part of said plurality of sensors in the sensor array; an average photometric sensor which detects an average brightness at the photographic screen; an average luminance computing section which calculates an average luminance value at the photographic screen based on an output of the average photometric sensor; a subject state judgment section which determines a state of the subject by comparing the average value of the sensor outputs with the average luminance value; an optical sensor which detects a luminance value of an average brightness at a wavelength area different from a photometric wavelength area detected by the average photometric sensor at the photographic screen; a subject field state judgment section which determines a state of a subject field including the subject by comparing the average luminance value with the luminance value detected by the optical sensor; and an exposure control determining section which determines exposure control during photographing based on the average luminance value and results of determinations of the subject state judgment section and the subject field state judgment section.
