Abstract
Image data obtained through image capturing are held on an internal memory 23. The image data are compressed by a CPU 22, recorded on a memory card 45, and sent by a communications interface 46, a Bluetooth™ transmission module 50, a portable telephone function unit 52 or the like. The CPU 22 is capable of compressing the image data at different compression ratios which are different between recording and sending. In this case, the image data held on the internal memory 23 are compressed at the different compression ratios and recorded in mutually different recording regions of the memory card.
Claims8
A camera which is capable of recording and sending image data, comprising:
- a temporary memory which holds image data obtained through image capturing;
- a data compressor which accepts setup regarding a compression ratio for sending and accepts setup regarding a compression ratio for recording, and accordingly compresses the image data recorded on the temporary memory at the respective compression ratios;
- and
- a memory controller which ensures that the image data compressed at the compression ratio for sending and the image data compressed at the compression ratio for recording are recorded independently in different regions of a memory.
A digital camera comprising:
- a data compressor which compresses image data obtained through image capturing;
- a temporary memory which holds the image data as they are before compressed by the data compressor;
- recorder which is capable of recording the data compressed by the data compressor on a recording medium;
- sender which is capable of sending the data compressed by the data compressor;
- and
- a compression ratio controller which is capable of independently setting a compression ratio for the data recorded by the recorder and a compression ratio for the data sent by the sender,
- wherein the data compressor compresses the image data at the compression ratios which are set by the compression ratio controller.
A digital camera comprising:
- a data compressor which compresses image data obtained through image capturing;
- a temporary memory which holds the image data as they are before compressed by the data compressor;
- recorder which is capable of recording any one of the image data as they are before compressed and the data compressed by the data compressor;
- sender which is capable of sending any one of the image data as they are before compressed and the data compressed by the data compressor;
- and
- a compression ratio controller which is capable of independently setting a compression ratio for the data recorded by the recorder and a compression ratio for the data sent by the sender.
