Title:
COORDINATE DATA INPUT ERROR ABSORBING DEVICE
Document Type and Number:
Japanese Patent JP3896106
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a coordinate data input error absorbing device which discriminates which of an error of hardware and displacement for input the inputted coordinate data is, and prevents essential coordinate data from being lost regardless of inversion of the direction of displacement.
SOLUTION: Coordinate data indicating a depressed position on a touch panel covering the front surface of a display screen part 103 is detected by a coordinate detection means 106 and is stored in a coordinate data storage means 108. A determination means 117 determines which of an error of hardware and displacement the inputted coordinate data is. When it is determined as displacement, a moving average method calculation means 118 selects a threshold stored in a determination parameter storage means 109 in a displacing state and calculates inputted coordinates.
