摘要： Image feature values Va and Vb are derived from image data, coefficients C and D are determined based on the image feature values Va and Vb, and an approximate expression expressed with the file size Sfj of the JPEG compression file and the quantization data coefficient value Aqt is derived. Next, by designating the file size of a desired predetermined JPEG compression file based on the approximate expression, the quantization data coefficient value Aqt is derived, and a first quantization table as a reference is multiplied by the quantization data coefficient value Aqt, whereby a second quantization table is obtained. Then, using the second quantization table, the image data is actually JPEG-compressed.

摘要： A single-lens reflex camera comprises a taking lens having a zooming optical system, a finder whose angle of view is determined according to a focal length of the taking lens, and an operation member which is manually operated. In the single-lens reflex camera, the focal length of the taking lens is changed by driving the zooming optical system, and the zooming operation is controlled in response to an operation of the operation member so that the focal length of the taking lens is changed in the wide-angle direction by a predetermined amount. An angle of view corresponding to that which is seen before the focal length is changed is displayed within the finder.

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.
