Abstract

A device editing a value of a parameter according to an operation by a user operates in a normal mode and in a detailed edit mode. In the normal mode, according to an operation sensed by a touch panel, the position of a cursor in a main screen displayed on a display panel is controlled, and a parameter to be edited is selected and an operation mode is shifted to the detailed edit mode. In the detailed edit mode, a screen for accepting an edit operation of the parameter selected in the normal mode is displayed on a touch screen and a value of the parameter stored in a current memory is changed according to the operation sensed by the touch panel.

Claims

1. A parameter editor, comprising:

a first display;

a second display including a sensor sensing an operation by a user;

a first accepting device that accepts a selection instruction of a parameter to be edited in a screen displayed on said first display, based on the operation sensed by the sensor;

a second accepting device that, in a case where the selection instruction is accepted, causes said second display to display a screen for accepting an edit operation of the selected parameter and accepts an edit instruction of the parameter in the screen displayed on the second display, based on the operation sensed by the sensor; and

a parameter editing device that changes a value of the parameter according to the instruction accepted by said second accepting device.

2. The parameter editor according to claim 1,

wherein, in a state where said second accepting device accepts the edit instruction of the parameter, the operation sensed by the sensor is not handled as an operation to the screen displayed on said first display.

3. A signal processor comprising:

a memory storing values of a plurality of parameters;

a signal processing device performing signal processing based on the values of the parameters stored in said memory;

a first display displaying a main screen displaying contents regarding the plural parameters;

a second display including a touch panel; and

a controller performing control according to a mode,

wherein the mode includes;

a first mode in which, according to an operation sensed by the touch panel, said controller controls a position of a cursor in the main screen and shifts to a second mode after a parameter to be edited is selected; and

the second mode in which said controller causes said second display to display a detailed edit screen for accepting an edit instruction of the parameter selected in the first mode, and according to an operation sensed by the touch panel, changes a value of the parameter for which the edit instruction is accepted in the detailed edit screen, out of the parameters stored in said memory.

4. The signal processor according to claim 3,

wherein, in the second mode, the operation sensed by the touch panel is not handled as an operation to the main screen.
