ABSTRACT:
A camera in which the compressibility of digital image data is controlled by a focus signal. The camera includes an imaging device and a photographic optical system which forms a subject image on the imaging device, the imaging device converting the subject image into electrical signals. A focus detection device is coupled to the photographic optical system and focuses the photographic optical system. The focus detection device also provides a corresponding focus output signal. An analog-to-digital conversion unit receives the electric signals from the imaging device and converts the electric signals into digital signals. A compression unit receives the digital signals from the analog-to-digital conversion unit and the focus output signal from the focus detection device and compresses the digital signals at a compressibility corresponding to the focus output signal.
