摘要： A multi-point photometric apparatus for use in a camera or the like operative to measure the luminance of several divided areas in an objective field. Among the luminance signals produced by the photometric circuit for the several areas, a signal from one area which is used for automatic focus adjustment is designated as a reference value, and the maximum and minimum values of luminance signals and the differences of these from the reference value are evaluated. The reference value and differences in the form of digital data and information on the film latitude are processed with a microprocessor to calculate the exposure value. The exposure value is modified to an extend that the reference remains within the film latitude.

摘要： An optical system has a diffractive optical element. A diffractive optical surface of the optical element has a blaze-shaped diffraction grating. The grating heights are smaller in the peripheral region of the grating than in the central region of the grating around its optical axis. The optical element acts as a lenses a result of light rays being deflected by the light-diffracting action of the diffractive optical surface.

摘要： Brightness of a central area in a scene to be photographed and brightness of a peripheral area around the central area are measured, and the brightnesses of respective areas are outputted as first and second values. When the second value is larger than the first value, the first value is corrected by a value which has no relation with the respective measured values. Consequently, a proper controlling brightness value is provided for controlling the exposure.
