Abstract
Provided is a method for adaptively compressing image data. A refresh rate and a compression rate of the image data are determined based on motion information of the image data, and the image data are compressed based on the determined refresh rate and compression rate.
Claims11
A method, executed by at least one processor, for adaptively compressing image data, the method comprising:
- determining, by the at least one processor, both a refresh rate and a compression rate of the image data based on motion information of the image data;
- and
- compressing, by the at least one processor, the image data based on the determined compression rate and outputting, by the at least one processor, the compressed image data based on the determined refresh rate,
- wherein a value of the refresh rate is determined to be proportional to a motion of the image data and a value of the compression rate is determined to be inversely proportional to the motion of the image data,
- wherein the determining comprises:
- classifying, based on the motion information of the image data, the image data into first image data having a small motion, second image data having a medium motion, and third image data having a large motion;
- and
- determining a first refresh rate having a lowest refresh rate and a first compression rate having a lowest compression rate for the first image data, a second refresh rate having a medium refresh rate and a second compression rate having a medium compression rate for the second image data, and a third refresh rate having a highest refresh rate and a third compression rate having a highest compression rate for the third image data.

A device for adaptively compressing image data, the device comprising:
- at least one processor;
- and
- a memory storing a program which is executed by the at least one processor to cause the at least one processor to:
- determine both a refresh rate and a compression rate of the image data based on motion information of the image data;
- and
- compress the image data based on the determined compression rate and output the compressed image data based on the determined refresh rate,
- wherein a value of the refresh rate is determined to be proportional to a motion of the image data and a value of the compression rate is determined to be inversely proportional to the motion of the image data,
- wherein the at least one processor classifies, based on the motion information of the image data, the image data into first image data having a small motion, second image data having a medium motion, and third image data having a large motion, determines a first refresh rate having a lowest refresh rate and a first compression rate having a lowest compression rate for the first image data, a second refresh rate having a medium refresh rate and a second compression rate highest refresh rate and a third compression rate having a highest compression rate for the third image data.
