摘要： A data reading device for a camera can provide a data being accurate with high probability through repeated data reading of a code pattern on a film cartridge even in hard conditions, such as a condition where contact between contact terminals of the device and code regions of the code pattern is unstable and a condition where the resistance value of a conductive code region is comparatively high or varies with the area on which the corresponding contact terminal abuts. In one operation example of an embodiment, the device discriminates consistency and inconsistency between the contents of the successively read data bit by bit and substitutes the contents of the later read data discriminated as being inconsistent for those of the previously read data only when the inconsistency discriminated contents of the later read data indicate conduction of the corresponding code regions. The previously read data is thus renewed again and again so as to more accurately correspond to the data indicated by the code regions of the code pattern.

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.
