Electronic apparatus, image compression method thereof, and non-transitory computer readable recording medium

An image compression method of an electronic apparatus, the method comprising:

• receiving image data;
• converting a pixel value of a frame constituting the received image data to a first data value using a preset algorithm;
• determining an offset for reducing a number of bits of the first data value based on a first range of a converted first data value;
• adding the offset to the first data value to generate a second data value;
• and
• generating and storing compressed data formed by compressing the second data value,
• wherein a header of the compressed data comprises information on the number of bits of the second data value and the offset.

A non-transitory computer readable medium having recorded thereon a program for executing an image compression method of an electronic apparatus, the method comprising:

• receiving image data;
• converting a pixel value of a frame constituting the received image data to a first data value using a preset algorithm;
• determining an offset for reducing a number of bits of the first data value based on a range of a converted first data value;
• adding the offset to the first data value to generate a second data value;
• and
• generating and storing compressed data formed by compressing the second data value,
• wherein a header of the compressed data comprises information on the number of bits of the second data value and the offset.
