  • Patent number: RE32376
    Abstract: An improved exposure control apparatus for camera comprises a metering circuit, exposure operational circuit, correction value calculating circuit and correction operational circuit. The metering circuit meters a plural number of divisional sections of the field of an object and generates a plural number of photoelectric outputs corresponding to the respective sections of the field. The exposure operational circuit calculates an exposure value from the plural number of photoelectric outputs. The correction value calculating circuit calculates correction values for correcting the distribution characteristics of said photometric outputs relative to the distribution characteristics of illumination on the focal plane of the photographing lens of the camera at the time of photographing, the correction values corresponding to the sections of the field respectively.
