1. A data conversion device, which performs a data conversion process for causing a frame memory to memorize display data
of a past frame and for causing a data conversion section to generate calculation data serving as display data of a frame
after the past frame on a basis of the display data of the past frame and display data of a present frame, so as to output
as output display data the calculation data to a display device, comprising:
a compressing section for outputting compressed data to be memorized in the frame memory for each frame, the compressed data
having been subjected to a compression process by replacing
one or more components constituting the display data of each pixel and other one or more components constituting display data
of a pixel existing around that pixel on a screen
with
one or more alternative values calculated by adding said one or more components and said other one or more components to each
other after these components have been weighted so as to reduce an amount of data; and
a restoring section for outputting restored data to the data conversion section so that the restored data is to be converted,
the restored data having been subjected to a restoration process by reading out the compressed data from the frame memory
and allotting the alternative value as display data for each corresponding pixel.
