Abstract
An image data encoding device includes a data block generating unit configured to split image data into a plurality of data blocks, and a compressing unit configured to generate compressed data with respect to each of the plurality of data blocks, the compressed data including position information regarding positions of first pixels each having a gray scale value equal to a reference gray scale value, and difference values between the reference scale value and gray scale values of second pixels, which are different from the reference gray scale value.
Claims11
An image data encoding device comprising:
- a data block generating unit configured to split image data into a plurality of data blocks;
- and
- a compressing unit configured to generate compressed data with respect to each of the plurality of data blocks, the compressed data comprising:
- position information regarding positions of first pixels each having a gray scale value equal to a reference gray scale value;
- and
- difference values between the reference scale value and gray scale values of second pixels, which are different from the reference gray scale value.
An image data encoding method comprising:
- splitting image data into a plurality of data blocks;
- determining a number of first pixels having a gray scale value equal to a reference gray scale value for each of the data blocks;
- generating position information regarding positions of the first pixels when the number of the first pixels is greater than or equal to a reference number;
- calculating difference values between the reference gray scale value and gray scale values of second pixels, which are different from the reference gray scale value;
- and
- generating compressed data including the position information and the difference values.
