Abstract: A touch panel system includes a closeness detection section 102 for detecting whether or not a position pointing member is brought close to a touch panel, a coordinate calculation section 108 for calculating the coordinate value on the detection face when the position pointing member is brought close to the detection face, and a control unit 100 for displaying the setting of the current set function at a position of the detection face corresponding to the coordinate value if the closeness detection section 102 detects that the position pointing member is close to the detection face for a preset first time or more.

Abstract: Still color image data is separated into plural planes, and pixels of each plane are processed predictive coding within plane and/or between planes, and the predictive error data is modified by using the correlation of predictive errors within plane and/or between planes, and the modified data is coded by entropy coding so as to curtail the quantity of data, thereby realizing high speed and efficient predictive coding.
