First Claim
1. A camera for use with a memory medium detachably attachable to said camera, said memory medium being capable of storing compressed image data and information to be used for image data compression, said camera comprising:
- (a) an image sensor which senses an image of an object and produces image data;
(b) a connector which connects the memory medium to the camera in order to read out the information from said memory medium;
(c) a processor which automatically sets a compression ratio based on the read-out information; and
(d) a data processor which compresses the image data produced by the image sensor at the set compression ratio.

Abstract
A camera includes an image sensor for sensing an image of an object to be photographed and producing an image data, a first memory for storing information concerning compression, a setting device for setting a compression ratio based on the information stored in the first memory, a compression device for compressing the image data at the set compression ratio, and a second memory for storing the compressed image data. Also, This camera includes a displaying device for displaying an image corresponding to the compressed image data in the viewfinder system so that the photographer can observe the image quality deterioration caused by the compression.
