Specifically, the set character font “Gothic” and the set character size “18” of the display device 20 are read from the device setting storage area 241 of the RAM 24. When the process of step S406 is performed, the display height of the lyrics information shown in (2) of FIG. 7 is changed to the display height “70” shown in (3) of FIG. 7 according to the set character size.

  In step S406, for the reference setting information acquired from the lyrics management server 50, the character font type for which the reference character font “Mincho” is set is changed to the set character font “Gothic”. Note that the character fonts of different types have different horizontal display widths even when the same character is displayed on the display 21.

  In step S407, the display width when each phrase of the lyrics information is drawn on the display 21 with the set character font of the display device 20 is obtained. When step S407 is executed, for example, the display width of each phrase of the lyrics information shown in (2) of FIG. 7 is set to the display width shown in (3) of FIG. When the processing in step S407 is performed, the lyrics information in which the start coordinates, the display width, and the display height are changed by the processing in steps S404 to S407 is stored in the processing lyrics information storage area 243.

  In step S408, it is determined whether or not the processing from step S404 to step S407 has been performed for all lyrics information. When it is determined that the start coordinates, the character font, and the character size have been changed for all lyrics information (step S408: YES), the size changing process is terminated. If it is not determined that the start coordinates, the character font, and the character size have been changed for all lyrics information (step S408: NO), the process of step S404 is repeated.

  When the size change process is completed, the position adjustment process in step S50 shown in FIG. 5 is performed. The position adjustment process performed in step S50 will be described with reference to FIGS. FIG. 8 is a flowchart showing the processing procedure of the position adjustment processing. FIG. 9 is an explanatory diagram showing changes in the display result displayed on the display 21 of the display device 20 in accordance with the position adjustment process.

  In step S501 shown in FIG. 8, lyrics information of a plurality of phrases to be displayed at one time is read from the acquired information storage area 242.

  In step S502, each phrase read in step S501 is provisionally arranged on the display 21 so as to be arranged with each set value of the lyrics information.

The screen length A of the display 21 is the length from one end side of the display 21 to the other end side on the opposite side, that is, the length from the left end side to the right end side as shown in FIG.

  In step S504, it is determined whether the arrangement width is longer than the screen length as a result of the comparison in step S503. If it is determined that the arrangement width is longer than the screen length (step S504: YES), step S505 is performed. If it is not determined that the arrangement width is longer than the screen length (step S504: NO), step S510 is performed.

  In step S505, the start interval X0 is compared with the difference XA between the arrangement width X and the screen length A. The start interval X0 is the length from the left end side of the display 21 to the X coordinate where the phrase is drawn. If it is determined that the phrase start interval X0 is longer than the difference XA between the arrangement width X and the screen length A (step S505: YES), step S508 is performed. For example, as shown in (1A) of FIG. 9, when the phrase start interval X0 is longer than the difference XA between the arrangement width X and the screen length A, step S507 is performed. If it is not determined that the phrase start interval X0 is longer than the difference XA between the arrangement width X and the display length A (step S505: NO), step S506 is performed. For example, as shown in (2A) of FIG. 9 and (3A) of FIG. 9, when the start interval X0 is shorter than the difference XA between the arrangement width X and the screen length A, step S506 is performed.

  In step S506, the sum of the phrase start interval X0 and the interval X1 between the phrases is compared with the difference XA between the arrangement width X and the screen length A. If it is determined that the sum of the phrase start interval X0 and the interval X1 between a plurality of phrases is longer than the difference XA between the arrangement width X and the screen length A (step S506: YES), step S509 is performed. For example, as shown in (2A) of FIG. 9, when the sum of the phrase start interval X0 and the plurality of phrase intervals X1 is longer than the difference XA between the arrangement width X and the screen length A, step S509 is performed. . If it is not determined that the sum of the phrase start interval X0 and the plurality of phrase intervals X1 is longer than the difference XA between the arrangement width X and the screen length A (step S506: NO), step S507 is performed. For example, as shown in (3A) of FIG. 9, when the sum of the phrase start interval X0 and the plurality of phrase intervals X1 is shorter than the difference XA between the arrangement width X and the screen length A, step S507 is performed. .

  In step S507, when it is determined in step S505 that the phrase display start position is longer than the difference between the arrangement width and the display length, the phrase display start position is moved to one end side of the display 21 by the length of the difference. . For example, as shown in (1A) of FIG. 9, when the phrase start interval X0 is longer than the difference XA between the arrangement width X and the screen length A, as shown in (1B) of FIG. 9, the phrase start interval X0 is moved and displayed on the left end side of the display 21 by the difference XA. When there are a plurality of phrases displayed on the display 21, as shown in (1B) of FIG. 9, the display start positions of all the phrases are moved and displayed on the left end side of the display 21 by the difference XA. The

  In step S508, when it is determined in step S506 that the sum of the phrase display start position and the interval between the plurality of phrases is longer than the difference between the arrangement width and the screen length, the phrase display start position and the plurality of phrase The phrase display start position is moved to the left end side of the display 21 in accordance with the ratio between the sum of the intervals and the difference. When there are a plurality of phrases displayed on the display 21, the display start positions of all phrases are moved and displayed on the left end side of the display 21 by the difference. Specifically, the phrase display start position is determined according to the ratio between the start interval X0 and the difference XA. The phrase interval is determined according to the ratio between the phrase interval X1 and the difference XA.

  In step S509, when it is not determined in step S506 that the sum of the phrase start interval X0 and the interval X1 between the phrases is longer than the difference XA between the arrangement width X and the screen length A, it is displayed on the display 21 at a time. The entire phrase is displayed so as to fall within the display resolution range of the display 21. For example, as shown in FIG. 9 (3A), when the sum of the phrase start interval X0 and the interval X1 between the phrases is shorter than the difference XA between the arrangement width X and the screen length A, As shown in 3B), the entire display 21 is reduced so that all the phrases to be displayed are displayed. Specifically, the ratio between the arrangement width X and the display resolution of the display 21 is obtained, and the phrase start interval X0, the interval X1 between a plurality of phrases, and the character size are reduced by the ratio obtained in the ratio. Is done.

  In step S510, the phrase is displayed on the display 21 according to the lyrics information in which each value is changed in step S507, step S508, or step S509.

  In step S511, it is determined whether or not the phrase position adjustment for all display screens has been completed for the lyrics information corresponding to the music. If it is determined that the position adjustment of all the phrases of the lyrics information corresponding to the music has been completed (step S511: YES), the position adjustment process is ended. If it is not determined that all the position adjustments of the lyrics information have been completed (step S511: NO), the process of step S501 is performed.
