Method, apparatus, and computer-readable recording medium for efficiently performing embedded compression of data

A method of performing embedded compression (EC) on image data, the method comprising:

• obtaining decoded image data that is decoded from encoded image data;
• determining a block size of image data to be embedded compressed from among the received image data;
• and
• comparing the determined block size with a first EC block size for embedded compression,
• if the determined block size is equal to or greater than the first EC block size, embedded compressing the received image data;
• and
• if the determined block size is smaller than the first EC block size,
• a) embedded compressing the image data, which is to be embedded compressed, in a second EC block size determined according to the determined block size;
• and
• b) storing the embedded compressed image data and tag information of the embedded compressed data.

An apparatus for performing embedded compression (EC) on image data, the apparatus comprising:

• an input unit configured to obtain decoded image data that is decoded from encoded image data;
• a control unit configured to determine a block size of image data waiting for embedded compression from among the received image data and compare the determined block size of the image data waiting for embedded compression with an EC block size that is an embedded compression unit;
• and
• an embedded compression unit configured to, if the determined block size of the image data waiting for embedded compression is equal to or greater than the EC block size, embedded compress the received image data, and if the determined block size of the image data waiting for embedded compression is smaller than the EC block size, store tag information of the received image data.
