发明名称 INFORMATION PROCESSING APPARATUS AND CONTROL METHOD THEREFOR
摘要 PROBLEM TO BE SOLVED: To solve the following problem: when information of each touch point is acquired one point by one point out of a touch panel, false recognition sometimes occurs in response to a multi-touch operation in which a user operates a plurality of touch points simultaneously.SOLUTION: In an information processing apparatus, in which multi-touch operation can be performed, an acquisition part 112 acquires a distance between two touch points constituting the multi-touch operation every time a detection part 111 detects a position of each of a plurality of touch positions, constituting the multi-touch operation, one point by one point; and a determination part 114, which determines a multi-touch operation input to the device, determines, when the distance between the two touch points is successively enlarged, that it is an operation for causing an image displayed on a display part to be enlarged, or determines, when the distance between the two touch points is successively reduced, that it is an operation for reducing the image.
