摘要： A camera exposure data setting device for setting exposure data in digital form in response to on or off of switches. A first switch actuating member is manually operable for changing mainly an exposure time value and is located at or about the position where a shutter speed setting dial is located conventional cameras, and a second switch actuating member is manually operable for changing mainly a diaphragm aperture value and is located at a position of the camera opposite from the position of the first switch member with respect to the vertical plane passing the optical axis of an objective lens. The first switch actuating member is operated for changing the exposure time value in an exposure time priority automatic exposure control mode and a manual exposure control mode and changing the diaphragm aperture value in a diaphragm aperture priority automatic exposure control mode, and the second switch actuating member is operated for changing the exposure time value in the exposure time priority automatic exposure control mode and the diaphragm aperture value in the exposure time priority automatic exposure control mode and the manual exposure control mode.

摘要： A display device for use in a camera comprises a central processing unit and display units to display exposure data and various control modes under the control of the CPU. The display units are arranged to display the exposure data with suitable marks or characters in rows so as to make the operator to read the display easily. The CPU provides control data to deenergize the display unit at the time of initial states of the camera such as at the time of loading a battery in the camera to prevent to display confusing information.

摘要： A release operation of a camera adapted to be transferred to a normal photographing condition through winding-up of a film by a predetermined length is allowed in conditions before transfer to the normal photographing condition even if a release inhibition signal is being generated. Whether or not the camera is in the normal photographing condition is determined based on the state of a switch which is turned OFF upon transfer of the camera to the normal photographing condition. The turn-OFF of the switch always causes the camera to read a code pattern on a film cartridge to automatically set the film sensitivity represented by the code pattern. The camera is also capable of manual film speed setting. When a new battery is loaded in the camera while it is the normal photographing condition in and while a film cartridge with no code pattern is being used, the camera is adapted to start light measurement and exposure calculation only when a film sensitivity setting switch which allows manual film sensitivity setting is turned ON, thereby urging a camera operator to verify the film sensitivity of the film. In contrast, when a new battery is loaded in the camera while it is in the normal photographing condition when a film cartridge with the code pattern is being used, the camera reads the code pattern upon detection of loading of the battery.
摘要翻译： 即使产生了释放禁止信号，在转移到正常拍摄条件之前的条件下，允许通过将胶片卷起预定长度而转印到正常拍摄状态的相机的释放操作。 基于在将相机转移到正常拍摄条件时关闭的开关的状态来确定相机是否处于正常拍摄状态。 开关的关闭总是使相机读取胶片暗盒上的代码图形，以自动设置由代码图案表示的胶片感光度。 相机还可以手动胶片速度设定。 当在正常拍摄条件下装入新的电池时，在使用没有代码图案的暗盒的情况下，相机适用于仅当允许的胶片感光度设置开关时开始光测量和曝光计算 手动胶片感光度设置被打开，从而促使相机操作者验证胶片的胶片感光度。 相反，当正在使用具有代码图案的暗盒的正常拍摄条件下，当照相机中装载新电池时，相机在检测到电池的负载时读取代码图案。

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 calculating device, for use in a camera having a programmed exposure control mode which automatically calculates a shutter speed and a diaphragm aperture value in a programmed manner, is further capable of modifying the combination of calculated shutter speed and aperture value in accordance with the manual operation. The amount of modification value is automatically reset in response to the detection of the operational condition of the camera, such as a detachment of an exchangeable lens, the charging completion of an electronic flash device, the camera exposure control by a camera accessory, and the change of the exposure control mode.
