摘要： A camera has an electronic viewfinder for displaying an image of a subject to be photographed in accordance with image data from a scene. The displayed image encompasses an area larger than that of the scene to be photographed, to enable the camera user to view objects and events outside of the photographic frame. In addition, the image data can be processed in accordance with differing photographic conditions, such as changes in shutter speed, aperture or electronic flash emission, to permit the user to view the changes that occur under the differing conditions.
摘要翻译：相机具有电子取景器，用于根据来自场景的图像数据显示要拍摄的被摄体的图像。所显示的图像包含比要拍摄的场景大的区域，以使照相机用户可以观看摄影框之外的对象和事件。此外，可以根据不同的拍摄条件（诸如快门速度，光圈或电子闪光发射的变化）来处理图像数据，以允许用户查看在不同条件下发生的变化。

摘要： A camera includes a manually operable member having a plurality of distance measuring areas and for switching between exposure correction and AF area and between single photographing and continuous photographing. A viewfinder of the camera displays not only an object but also the above-described respective functions displayed on a LCD and switchable by the manually operable member. As a result, a photographer is allowed to perform photographing while looking at not only the object but also the state of the various functions displayed on the LCD in the finder.
