Summary:PROBLEM TO BE SOLVED: To perform quick display of a partial region or quick scroll of a partial picture by developing picture compression data of large size without hindrance even if capacitor of a work memory has memory limit such that original picture data can be developed. SOLUTION: A bit position from the lead of a picture compression data stream is set every prescribed interval at the time of compression of picture data, developing of picture compression, and the like, a compression data offset value storing means 12 performing processing in which it is stored as a compression data offset value is provided, when a partial region in an original picture is specified, a scroll means 13 reads out an adequate compression data offset value, and makes a partial developing means 11 perform partial developing of picture compression data in the middle of a compression data stream. Consequently, a load of the scroll means 13 is reduced, over head of a processing time can be shortened.
