摘要： A system that is mounted in a camera capable of focal point detection and that performs correction of the focal point detection data in accordance with the temperature, wherein the temperature inside the photo-taking lens barrel is measured and the focal point detection data is corrected based on the temperature data for the interior of the photo-taking lens barrel. Using this construction, because the temperature of a lens element comprising the photo-taking lens can be accurately measured even where the ambient temperature of the camera has suddenly changed, for example, appropriate correction suitable for the temperature conditions may be performed. Also disclosed is a construction in which the correction of the focal point detection data is performed based on not only the temperature data but also the focal length data for the photo-taking lens. Using this construction, appropriate correction suitable for the temperature conditions may be performed even when, for example, the focal length of the photo-taking lens has changed.

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.
