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: An exposure control device for a camera having light measuring elements capable of outputting an average light measurement corresponding to the brightness of the entire scene to be photographed, and outputting a spot light measurement corresponding to the brightness of a part of the scene to be photographed, wherein an exposure control is carried out based on the spot or average light measurements. In an exposure control for daylight photography, the exposure control is carried out based on the average light measurement or based on the spot light measurement at the time of an AE lock, and for flash photography, the exposure control is carried out based on the average light measurement regardless of whether the AE lock operation is carried out.

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.
