<p><P>PROBLEM TO BE SOLVED: To adjust a parameter on the basis of touch operation to a touch-panel type display. <P>SOLUTION: Once a user performs touch operation on one of knob images 32 displayed on a display 17, a CPU 10 identifies the touch operation as first-type touch operation (S1:NO) and starts a state that the selection of a parameter represented by the selected knob image 32 is kept effective (S2-S5). Once the termination of the first-type touch operation is detected, the selection of the parameter is terminated (S5, S6). Furthermore, once new touch operation is detected while the parameter is selected via the first-type touch operation, the CPU 10 identifies the new touch operation as second-type touch operation (S1:YES) and changes the value of the currently selected parameter on the basis of a distance and a direction of the movement of the second-type touch operation (rotating operation) (S8). At that time, touch operation on a parameter image other than the currently selected parameter image is made invalid (S1, S7-S9). <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
