摘要： A flash case, in which a flash is provided, is automatically moved to an up position, when a user selects a flash mode in a state where the flash case is at a down position, when a user begins to forcibly raise the flash case by hand in a state where the flash case is at the down position, or when the flash case is at the down position in a state where a photometric operation starts in an auto-flash mode. The flash case is automatically moved to the down position, when an external force is added to the flash case at the up position.
摘要翻译：当用户在闪光灯壳处于向下位置的状态下选择闪光模式时，当用户开始强制地将闪光灯壳体升高时，闪光灯被提供的闪光灯盒被自动地移动到向上位置手动处于闪光灯壳处于向下位置的状态，或者当闪光灯在自动闪光模式下开始测光操作的状态下处于向下位置时。当在向上位置向外壳施加外力时，闪光灯盒会自动移动到向下的位置。

摘要： A camera has a viewfinder that forms a subject image to be observed, a multipoint auto-focus adjuster that focuses the subject image on the basis of multiple focus points defined on the subject image, a superimposer that superimposes an indicator mark on a position of a given focus point, and a focus point luminance detector that detects a luminance of the position. Then, the superimposer superimposes the indicator mark such that a brightness of the indicator mark increases as the luminance of the position increases.

摘要： A camera includes a built-in flash and a controller for controlling the camera. The controller includes different photographic modes; an auto-exposure-mode selecting mode in which an appropriate photographic mode is automatically selected from the different photographic modes based on photographic conditions, the controller allowing the built-in flash to discharge automatically in the selected appropriate photographic mode when the built-in flash discharges at a most appropriate time of exposure; and a flash-prohibiting/auto-exposure-mode selecting mode in which an appropriate photographic mode is automatically selected from the different photographic modes based on photographic conditions, the controller prohibiting the built-in flash from discharging automatically in the selected appropriate photographic mode at a time of exposure. The controller selects either the auto-exposure-mode selecting mode or the flash-prohibiting/auto-exposure-mode selecting mode in response to an operation of the manual operation member.
