In order to display the volume, SoC2 draws a line segment of the same length with the same center point as the scale as shown in FIG. 2 in the first color in a circle, that is, 360 degrees. . In FIG. 2, 240 line segments are drawn at intervals of 1.5 degrees. As illustrated in FIG. 3, the SoC 2 draws a volume bar (quantity bar) indicating the current volume (quantity) on the first scale with a second color different from the first color. In addition, the SoC 2 displays a bar indicating a volume lower than the current volume with a first color and a third color different from the second color and has an angle with respect to the horizontal direction of the scale than the volume bar. Draw on a small scale. In FIG. 3, 35 bars are displayed on a scale having an angle smaller than that of the volume bar.

The density is higher in the order of the second color, the third color, and the first color. The SoC 2 draws the scale on the first layer. The SoC 2 draws the volume bar and the bar on the second layer on the first layer.

  The SoC 2 displays a scale, a volume bar, and a part of the bar on the display unit 4, as shown in FIGS. Specifically, the SoC 2 displays a scale, a volume bar, and a bar within the range of 0 to 90 degrees on the scale on the rectangular display unit 4. Accordingly, the scale, the volume bar, and a part of the bar are cut into a rectangular shape and displayed on the display unit 4. Scales, volume bars, and bar portions that do not fit in the rectangular display unit 4 are not displayed on the display unit 4.

  As shown in FIG. 4, when the longitudinal direction of the smartphone 1 is the same as the vertical direction of the scale, the SoC 2 has a scale, a volume bar, and a bar so that the longitudinal direction is the same as the vertical direction of the scale. Is displayed on the display unit 4. That is, when the smartphone 1 is in the portrait orientation, the SoC 2 displays the scale, the volume bar, and a part of the bar in the portrait screen. The SoC 2 displays the current volume on the display unit 4 as a numerical value (“35” in FIG. 4). In the case of the vertical screen display, the SoC 2 displays the current volume as a numerical value on the upper left of the display unit 4.

  As shown in FIG. 5, when the longitudinal direction of the smartphone 1 is the same as the horizontal direction of the scale, the SoC 2 has a scale, volume bar, and bar so that the longitudinal direction is the same as the horizontal direction of the scale. Is displayed on the display unit 4. That is, the SoC 2 displays a scale, a volume bar, and a part of the bar in a horizontal screen when the smartphone 1 is in the horizontal direction. In the case of a horizontal screen display, the SoC 2 displays the current volume as a numerical value at the lower left of the display unit 4.

  Thus, in this embodiment, the display configuration (scale, volume bar, and bar) is common to the vertical screen display and the horizontal screen display. And SoC2 has changed the area | region (rectangular area | region) displayed by a vertical screen display and a horizontal screen display. As described above, since the display configuration is common to the vertical screen display and the horizontal screen display, it is not necessary to change the display configuration, and the vertical screen display and the horizontal screen display can be performed with a small number of processes. .

(Volume adjustment function)
The SoC 2 receives a touch operation on the touch panel 51 and a slide operation by the touch panel 51. The SoC 2 changes the volume when the touch panel 51 receives a touch operation and a slide operation on the touch panel. As shown in FIG. 6, the SoC 2 receives a touch operation on the volume bar and a slide operation in the upward direction, the diagonally upward right direction, the clockwise direction (arc shape), or the right direction, that is, When the slide operation within the range from the upper direction to the right direction is accepted, the volume is increased. At this time, the SoC 2 draws the volume bar on the scale corresponding to the current volume, as shown in FIG. Therefore, the volume bar moves clockwise on the scale. In addition, the SoC 2 updates a numerical value indicating the current volume at the upper left of the display unit 4 (“39” in FIG. 7).

  As shown in FIG. 8, when SoC 2 receives a touch operation on the volume bar and a slide operation in the downward direction, the counterclockwise direction (arc shape), the diagonally downward left direction, or the left direction, That is, when a slide operation within a range from the left direction to the lower direction is received, the volume is lowered. At this time, the SoC 2 draws the volume bar on the scale corresponding to the current volume, as shown in FIG. Therefore, the volume bar moves counterclockwise on the scale. In addition, the SoC 2 updates the numerical value indicating the current volume at the upper left of the display unit 4 (“29” in FIG. 9).

  Here, as shown in FIG. 10, when the user touches a position close to the center point of the scale and performs a slide operation, the sound volume changes greatly even if the moving distance is small because the user is close to the center point. There is. Therefore, in the present embodiment, when the touch operation to the touch panel 51 and the slide operation are received by the touch panel 51, the SoC 2 according to the distance from the touch position to the center point (predetermined center point) of the scale, Change the volume change rate.

  As shown in FIG. 11, SoC2 is a touch operation when the distance from the touch position to the center point of the scale is not less than the radius of the circle indicated by the solid line (predetermined first distance), that is, outside the circle indicated by the solid line. Is received, the volume is changed according to the speed of the slide operation. On the other hand, as shown in FIG. 11, SoC2 is a case where the distance from the touch position to the center point of the scale (predetermined center point) is shorter than the radius (predetermined first distance) of the circle indicated by the solid line, that is, When the touch operation is received within the circle indicated by the solid line, the change rate of the volume is slowed down. That is, SoC2 does not follow the speed of the slide operation and changes the volume with a delay. At this time, the SoC 2 draws the volume bar on the scale corresponding to the current volume. That is, SoC2 does not follow the speed of the slide operation and changes the volume bar with a delay. Accordingly, the user's finger is separated from the volume bar, and the volume bar changes after the finger.

  In addition, as shown in FIG. 11, SoC2 is when the distance from the touch position to the center point (predetermined center point) of the scale is shorter than the radius of the circle (predetermined second distance) indicated by the broken line, When a touch operation is received within a circle indicated by a broken line, the change rate of the volume is further reduced. That is, SoC2 does not follow the speed of the slide operation, and further changes the volume with a delay.

  FIG. 12 is a diagram showing a flow of determining the volume value. The SoC 2 determines the volume value from the coordinate position of the touch panel 51 that has accepted the touch operation. The SoC 2 draws an appropriate volume bar based on the determined volume value. In addition, when the volume value is changed, the SoC 2 executes drawing by generating a drawing update event.

  As described above, when the SoC 2 receives a touch operation outside the circle indicated by the solid line illustrated in FIG. 11, the SoC 2 changes the volume according to the speed of the slide operation. As illustrated in FIG. 13A, the SoC 2 does not change the change rate of the volume, but changes the volume to a specified value (30 → 40) (normal time). On the other hand, the SoC 2 changes the change rate of the sound volume when the touch operation is received in the solid circle or the broken circle shown in FIG. As shown in FIG. 13B, the SoC 2 does not immediately change the volume, but adjusts the volume gradually (30 → 31 → 32 →... → 39 → 40) (during adjustment). .

  When the touch operation on the volume bar and the slide operation are received by the touch panel 51, the SoC 2 controls the drawing update as follows. As shown in FIG. 14, SoC 2 is in a stopped state when the distance between the touch position and the drawing position (the final point of the slide operation) is less than X. When the distance between the touch position and the drawing position is equal to or greater than X, the SoC 2 shifts from the stop state to the transition state. SoC2 maintains the transition state when the distance between the touch position and the drawing position is X or more. If the distance between the touch position and the drawing position is less than X, the SoC 2 shifts to a stop state.

  Conditions for changing (adjusting) the rate of change in volume are as follows. SoC2 accepts a touch operation within a solid circle, and changes the change rate of the volume when the distance between the touch position and the drawing position (the final point of the slide operation) is greater than or equal to X (predetermined third distance). (Adjust). The SoC 2 accepts a touch operation within a broken-line circle, and when the distance between the touch position and the drawing position (the final point of the slide operation) is equal to or greater than X (predetermined third distance), the change rate of the volume Change (adjust).

  As described above, in the present embodiment, the SoC 2 draws a line segment having the same center point as the scale and having the same length in an arc shape with the first color. In addition, the SoC 2 draws a volume bar indicating the current volume on the scale with a second color different from the first color. Here, since the scale is drawn on the arc and the volume bar is drawn on the scale, when the longitudinal direction of the smartphone 1 is vertical, the area of the vertical screen is displayed on the display unit 4. When the display is performed and the longitudinal direction of the smartphone 1 is horizontal, the area of the horizontal screen may be displayed on the display unit 4. That is, the SoC 2 displays the scale and a part 4 of the volume bar on the display unit. Therefore, it is not necessary to change the display configuration between the vertical screen display and the horizontal screen display. As described above, according to this embodiment, since the display configuration is shared by a plurality of screen displays, a plurality of screen displays can be performed with a small number of steps.

  Moreover, in this embodiment, when SoC2 receives the touch operation to the touch panel 51 and the slide operation by the touch panel 51, according to the distance from the touch position to the center point of the scale (predetermined center point), Change the volume change rate. For example, when the distance from the touch position to the predetermined center point is shorter than the predetermined distance, that is, when the touch position is close to the predetermined center point, the SoC 2 slows the change rate of the volume. For this reason, even if the moving distance of the sliding operation is small, the volume is prevented from changing greatly.

  In the present embodiment, in the SoC 2, the distance from the touch position to the center point of the scale is less than a predetermined distance, and the distance from the touch position to the final point of the slide operation is greater than or equal to the predetermined distance. If so, slow down the rate of volume change. Therefore, if the slide distance is short, the volume does not change greatly, so the change speed of the volume is not slowed down.

  As mentioned above, although embodiment of this invention was described, the form which can apply this invention is not restricted to the above-mentioned embodiment, As suitably illustrated in the range which does not deviate from the meaning of this invention so that it may illustrate below. It is possible to make changes.

Not only this but SoC2 draws the same length of a line segment with the same center point as a scale in an arc shape with the first color, for example, from 0 degrees to 90 degrees. Good.

  In the above-described embodiment, the densities of the first color, the second color, and the third color are different. Not only this but the color should just differ.

  In the above-described embodiment, the volume is exemplified as the quantity. However, the quantity is not limited to this, and may be, for example, a fast-forwarding amount or a fast-rewinding amount of music.
