PROBLEM TO BE SOLVED: To realize a data conversion device which can suppress the capacity of a necessary frame memory by compression (reduction) of data, and at the same time suppress a decrease in display quality due to the compression (reduction) of data. SOLUTION: The data conversion device 11 of the present invention includes: a coding section 13 for replacing components of at least one kind constituting display data of each pixel and other components constituting display data of a pixel adjacent that pixel on a screen during display on the screen with average values of both the components to reduce an amount of data; and a decoding section 15 for reading out compressed data from the frame memory 14 and then allotting the average value as display data for each corresponding pixel. Therefore, unlike a case of adopting a conventional general data compression method, the data conversion device of the present invention can prevent deviation between original display data and display data obtained by a compression/restoration process from becoming large.
