<p>Disclosed is a compression device including a memory, an elongation unit, and an adder. The memory comprises: a first area storing a first integration value of a first pixel among pixels of a pixel group; a second area storing the first selection information related to a selected model to calculate a first prediction value to the second integration values of peripheral pixels besides the first pixel among the pixels of the pixel group; and a third area storing the first differences between the second integration values and the first prediction value. The elongation unit obtains the second integration values by using information stored in the first to third area. The adder obtains a third integration value by adding a first present brightness value of the first pixel to the first integration value, and obtains a fourth integration value by respectively adding the second present brightness values of the peripheral pixels to the second integration values.</p> |
