Image pickup system with separable/attachable image pickup device and display device

An image pickup system, comprising:

• a camera main body;
• a display apparatus for display an image which is picked-up by said camera main body, said display apparatus being detachable from said camera main body;
• compression encoding means for compression-encoding image data output from said camera main body, said compression encoding means being capable of compression-encoding the image data with a plurality of different compression methods;
• and
• radio transmission means for modulating the image data compression-encoded by said compression encoding means and transmitting the image data to said display apparatus through a radio transmission path,
• wherein said compression encoding means changes the compression method according to the attachment/detachment status of said display apparatus with respect to said camera main body.

An image pickup system, comprising:

• an image pickup apparatus for picking-up an image of an object;
• and
• first compression encoding means for compression-encoding image data output from said image pickup apparatus, with a first compression method;
• second compression encoding means for compression-encoding the image data output from said image pickup apparatus, with a second compression method;
• radio transmission means for modulating first image data compression-encoded by said first compression encoding means and transmitting the first image data through a radio transmission path to a display apparatus which displays an image picked-up by said image pickup means, the display apparatus being detachably mounted on said image pickup apparatus;
• recording means for recording the second image data compression-encoded by said the second compression encoding means;
• and
• control means for controlling said first and second compression encoding means so as to output the first image data to said radio transmission means in a case where the display apparatus is not connected electrically and mechanically to said image pickup apparatus, and so as to output the second image data to said recording means in a case where the display apparatus is connected electrically and mechanically to said image pickup apparatus.

An image input apparatus, comprising;

• image input means for inputting image data;
• a display apparatus for displaying an image input by said image input means, said display apparatus being mounted detachably on said image input apparatus;
• and
• output means for compressing the image data input by said image input means at a first compression ratio to output the compressed image data to said display apparatus through a radio transmission path in a case where said display apparatus is not connected electrically and mechanically to said image input apparatus, and for compressing the image data input by said image input means at a second compression ratio to record the compressed image data on a recording medium and to output the image data to said display apparatus in a case where said display apparatus is connected electrically and mechanically to said image input apparatus.
