PROBLEM TO BE SOLVED: To reduce the quantity of data which are changed during the transfer of them by converting a 1st image data part included in the image data into those which are more similar to a 2nd image data of a type different from the 1st image data part in the binary number representation that is divided into blocks in every finite bit number and restoring the converted 1st image data part into its original state after transferring them. SOLUTION: It's supposed that the image data include many image data parts (a) 0000 and (b) 1111. When the entire image data are processed (addition of +1) via an adder 300 before the image data are transferred via a data line 400, the image data parts (a) 0000 and (b) 1111 are turned into (a) 0001 and (b) 0000 respectively. Thereby the number of transited image data is reduced down to 1 (after processing) from largest 4 (before processing). These two types of image data parts, i.e., 0001 and 0000 to be compared with each other become similar to each other when they are processed.
