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 exposure display device for a camera, which can display not only the density of the background to be photographed on a film but also the density of a primary object to be focused with respect to an exposure control value used for exposure control operation. In natural light photography, the brightness of the primary object area at which automatic focus detection is conducted and the brightness of divided object field areas are measured, the density distribution of the primary object area and those of the divided object field areas reproduced on the film are calculated basing on the measurement, and the results are displayed in correspondence to the exposure control value. In flash light photography, the expected brightness of the primary object area and divided object field areas are measured, and the density distribution of the primary object area and object field areas reproduced on the film are calculated and displayed in correspondence to the exposure control value.

摘要： This invention is directed to a camera provided with an automatic focus adjusting apparatus in which, in addition to the function of carrying out an AE lock based on an in-focus detection, an AE lock can be carried out either before or after an AF operation is completed or when an AF operation is impossible. In other words, irrespective of the condition of an automatic focus adjusting means, an AE lock can be accomplished at any desired moment. Therefore, the degree of freedom in a photography operation is expanded.
