Problems solved by technology

As shown in FIG. 8B, when the operation surface 13a near the knob 13d is traced in a substantially straight line from bottom to top, the reverberation becomes stronger when the knob 13d is rotated to the right.

no. 2 Embodiment approach

[0064] Below, based on Figure 5 A second embodiment of the present invention will be described. Figure 5 is a flowchart showing the flow of processing executed by the CPU 17 . The display device 10 of the present embodiment is characterized in that excessive rotation of the knob can be prevented. In addition, in the display device 10 of the present embodiment, in addition to the Figure 5 Except for the processing, they have the same structure and function as the display device 10 of the first embodiment, so the description of the same part will be omitted below, and the same reference numerals will be used for the same structure.

[0065] The CPU 17 determines whether or not the knob ( Figure 6 ) to rotate to the right (S30). Here, when the CPU 17 determines in the affirmative (S30: Yes), it determines whether or not the indication of the knob to be operated is close to the maximum value (S31). For example, although the adjustment value of the reverberation is not actu...

Embodiment approach

[0072] (1) The CPU 17 can also extract the feature of the tracing method based on the xy coordinate data acquired from the touch panel 13 , and determine the operation mode based on the extracted feature. For example, based on the xy coordinates of the start position at the time of tracing and the xy coordinates of the end position at the end of tracing, the movement distance Δx in the x-axis direction and the movement distance Δy in the y-axis direction are calculated, and the ratio of Δx to Δy is within a predetermined range. If it is within the specified range, it is determined as the rotary operation mode, and when it is outside the predetermined range, it is determined as the linear operation mode. For example, when the value of Δx / Δy is in the range of 0.5 to 2.0, the inclination of the traced trajectory is neither too large nor too small, so it is estimated that the trace is traced in an arcuate shape. Then, when it is determined that the latest history in which the val...

Abstract

In a display device according to the present invention, a linear operation mode, in which a predetermined image is changed by tracing an operation surface substantially along a straight line, and a circular-arc operation mode, in which a predetermined image is changed by tracing the operation surface substantially along a circular arc, are set as operation modes for changing predetermined images (for example, knobs 13b to 13e) displayed on the operation surface by tracing an operation surface (13a) of a touch panel (13). A CPU extracts the characteristic manner in which the operation surface is traced on the basis of predetermined information acquired from the touch panel (13) when the operation surface is being traced, determines one of the linear operation mode and the circular-arc operation mode as the operation mode on the basis of the extracted characteristics, and changes to the other one of the operation modes in response to a change in the characteristic manner in which the operation surface is traced.

Description

technical field [0001] The present invention relates to a display device having a touch panel, an image display method, and an image display program. Background technique [0002] Currently, such display devices are known as Figure 6 The display device 30 is shown. The display device 30 is a flat-panel display device, and an application program for creating music is installed. The display device 30 has a touch panel 13 , and a part of an image showing a digital mixer used for music production is displayed on an operation surface 13 a of the touch panel 13 . In the illustrated example, a plurality of knobs (Virtual knobs) are respectively shown, namely: knob 13b, which is used to adjust the volume (shown as Volume in the figure); shown as Pan) to adjust; the knob 13d, which is used to adjust the strength of the reverb (shown as Reverb in the figure) as a kind of effect; and the knob 13e, which is used to adjust the chorus as a kind of effect (shown as Chorus in the figure...
