摘要： An optical system has a diffractive optical element. A diffractive optical surface of the optical element has a blaze-shaped diffraction grating. The grating heights are smaller in the peripheral region of the grating than in the central region of the grating around its optical axis. The optical element acts as a lenses a result of light rays being deflected by the light-diffracting action of the diffractive optical surface.

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： 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.

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 flash apparatus which allows flashlight photographing of various subjects in a photographing screen in appropriate exposure by simple operation without failure. The flash apparatus comprises a flashlight emitting section having a predetermined irradiation angle with respect to a light emission optical axis, and irradiating direction changing means for automatically changing the direction of the light emission optical axis of the flashlight emitting section in response to subject information such as distribution information of brightness values of or distances to subjects in a photographing screen. Also a camera is disclosed which assures photographing of a main subject with appropriate exposure even when the main subject is in a backlighted condition or when another body is positioned nearer to the camera than the main subject.
