It is a mode for. When the music playback mode a21 is selected, the playback device 1 executes playback processing of music data recorded on the hard disk 16.

  FIG. 4 is a diagram illustrating a basic display example of the image display unit 151 of the image display device 15 with a touch panel during music data reproduction processing. As shown in FIG. 4, during playback of music data, a list of information such as song title, performer, performance time, etc. is displayed on the display screen. In the lower column, an operation button group for performing various operations such as fast-forwarding is displayed, and as one of them, a volume switching button b1 for shifting to a screen for adjusting the volume is arranged.

  When the display area of the volume switching button b1 is touched, that is, when the corresponding detection area on the touch panel 152 is touched, the display of the image display unit 151 is switched to the volume adjustment screen shown in FIG. As shown in FIG. 5, on the volume adjustment screen, a plurality of bars (16 in this example) in which a plurality of spots (points) are arranged in a radial pattern are displayed at the center. . The object c1 is a guide display for guiding a volume adjustment operation, and at the same time, a status display of the adjusted volume. FIG. 5 shows the state of the volume 0, and in this state, each spot constituting the object c1 is displayed with low luminance. In the following, spots displayed with low luminance are indicated by white circles, and spots displayed with high luminance are indicated by black circles. The display of + and − corresponding to the upper arrow indicates the operation direction corresponding to the increase / decrease of the volume.

  When the volume is increased from the state of volume 0, as shown in FIG. 6, the user touches an arbitrary area on the object c1 and performs a touch panel operation to draw a circle or an arc clockwise from there (sliding). Dynamic action: broken line arrow in the figure). FIG. 6 shows a state in which the volume is small, and a part of the spot from the start point bar to the bar corresponding to the small volume (spot portion close to the center) is a spiral figure corresponding to this touch panel operation. Is displayed with high brightness. Further, as shown in FIG. 7, when a touch panel operation that draws a circle or an arc in the clockwise direction is further performed, the volume is increased accordingly, and the bar in which the spot is displayed with high brightness is rotated in the clockwise direction. It will increase. FIG. 7 shows a state in the volume. In other words, this object c1 is firstly volumed at the central angle portion of a fan-shaped figure formed of a plurality of bars in which some or all of the spots are displayed with high brightness, that is, the angle of the main portion of each bar. Express the state of When a touch panel operation that draws a circle or an arc in the counterclockwise direction is performed, the volume is reduced accordingly, and the bar on which the spot is displayed with high brightness decreases counterclockwise.

  As shown in FIG. 7, until the state in the volume, the display is performed so that the high-intensity spot forms a spiral figure, but when reaching the state in the volume, all 16 bars are displayed. One of the spots is displayed with high brightness. Thereafter, as shown in FIG. 8 and FIG. 9, when a touch panel operation that draws a circle or an arc clockwise is further performed, the volume is increased accordingly, and the circle or arc is drawn. Proceed in the direction to display all spots of the corresponding bar with high brightness. FIG. 8 shows a state in which the volume is large, and FIG. 9 shows a state in a volume max in which all spots of all bars are displayed with high luminance. That is, the object c1 secondly represents the volume state by the length of the diameter of each bar (the spot portion displayed with high brightness). More specifically, the bar on which the spot is displayed with high brightness when the volume is large (FIG. 8) to the volume max (FIG. 9) is already partially displayed with high brightness in the volume (FIG. 6) state. Although it is displayed (360 ° high luminance display), the remaining spots are displayed with higher luminance to identify them.

  By performing such volume state display control, the playback device 1 of the present embodiment can finely adjust the output volume even with a small touch panel, and can simultaneously display the adjusted output volume. To do. FIG. 10 is a diagram showing the relationship between the spot display of each bar and the audio output level. This figure shows how the high-intensity part of the spot extends from the central part to the outer peripheral part as the audio output level increases in the display examples described so far.

  If display control is performed so that the bar spot is displayed with high brightness in order from one end to the other, the distinction from the state of the volume 0 shown in FIG. 5 to the state in the volume shown in FIG. However, it is necessary to increase the number of spots in order to express the volume size or volume max state shown in FIGS. On the other hand, according to the display control of the present embodiment, it is possible to express more states with the same number of spots. In addition, the touch panel operation that draws a circle in the clockwise direction to increase the volume and draws a circle in the counterclockwise direction to decrease the volume is sensuously similar to the operation of the conventional dial. It can be said that there is.

  In the examples shown in FIGS. 5 to 9, the operation position and the display position are substantially matched in order to easily show how the volume state is displayed in response to the touch panel operation such as drawing a circle. However, there is no relationship between them. As shown in FIG. 11, when an arc is drawn from an arbitrary position on the object c1, a center angle corresponding to the drawn arc, that is, volume adjustment and display control corresponding to the drawing amount are performed. That is, the operation position and the display position are completely independent. Then, by adjusting the volume according to the drawing amount proportional to the center angle, for example, the touch panel 152 is accidentally touched compared to the general method of adjusting the volume at the touched position. The advantage of preventing malfunctions that do not occur can also be created.

  Here, the operation principle of volume adjustment of the reproducing apparatus 1 will be described with reference to the flowchart of FIG.

  First, the CPU 11 determines whether or not a touch panel operation for drawing a circle or an arc has been performed by a notification from the detection unit 17 (step A1). If this touch panel operation is performed (YES in step A1), the CPU 11 subsequently detects the drawing amount and direction (step A2).

  If it is in the right direction (YES in step A3), the CPU 11 instructs the sound processing unit 20 to increase the volume according to the drawing amount (step A4), while it is in the left direction (in step A3). NO), an instruction is given to the audio processing unit 20 to reduce the volume in accordance with the drawing amount (step A5).

  Then, the CPU 11 reads the display data of the object c1 corresponding to the adjusted volume state from the ROM 12 (step A6), and changes the display of the object c1 on the image display unit 151 to the read display data. 14 is instructed (step A7).

  Thus, in the playback device 1 of the present embodiment, the output volume can be finely adjusted even with a small touch panel, and the adjusted output volume can be displayed simultaneously.

  In the above-described embodiment, an example in which a volume adjustment object is displayed on a dedicated volume adjustment screen has been described. However, in the case of an audio player with a camera, use of enjoying music while watching a captured image is also conceivable. Therefore, for example, as shown in FIG. 13, it is also effective to modify the display image so as to be superimposed on the display image.

  That is, the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. In addition, various inventions can be formed by appropriately combining a plurality of components disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, constituent elements over different embodiments may be appropriately combined.
