By the way, in the conventional karaoke apparatus, the lyrics displayed on the display together with the image information such as the video image are merely superimposed and displayed on the display image based on the image information. It was Therefore, if the background image has a color similar to the character string of the lyrics, the lyrics become unsightly. Therefore, conventionally, a margin has been formed around each character of a superimposed text string in a color that is clearly different from the displayed character to make the displayed character string easier to see.

However, in order to display a character with such a trimming, a character font having a trimming is prepared in advance, and the trimming font and the character internal portion are made to have different display colors by using the trimming font. I was taking the way to display. The method of preparing the trimming font in advance requires a large capacity memory such as a memory for storing the trimming font. Therefore, it is not suitable for a karaoke device that uses the above-mentioned synthesizer as a sound source device and is driven by performance information of accompaniment music and uses lyrics information stored separately from the background image.

The present invention has been made in view of the above-mentioned circumstances, and superimposes a character string of lyrics as a trimming font on image information using an ordinary simple character font with easy and simple processing. It is intended to provide a karaoke device that can display.

[0007]

A karaoke device according to the present invention is a karaoke device which plays accompaniment music of a singing song and displays a character string of lyrics superimposed on a background image on a display, at least one character at a time. A font data generating means for generating character font data of the character string of the lyrics;
A first character display means for making multiple display by shifting a predetermined minute amount in predetermined directions from the predetermined character display position in the display color with the display color, and the first display color different from the first display color by the character font data. Second character display means for displaying the predetermined character display position on the display in two display colors.

Further, without performing such processing character by character, for example, as shown in FIG. 9 (a), the character string "from the night train leaving Ueno" is changed to the font pattern of the character string. As described above, by inverting the character color, shifting in multiple directions by small amounts in multiple directions, and displaying multiple characters, by superimposing it and displaying the character of the predetermined display color at the regular position, the image shown in FIG. The whole character string can be made into a trimming font at once as shown in). As described above, it is possible to easily generate a trimming font from a normal character font by a simple process without preparing a character font for a special trimming font.

It should be noted that the display color when generating the trimming font only needs to be a color in which the original character portion and the trimming portion are different. For example, the trimming portion is the original display color, and the internal original character portion is The display color may be different from that. Further, the number of characters used to generate the framing font may be set appropriately according to the system conditions and the like. This trimming font generation method can be performed in the same manner even if the character font is not a dot pattern font but a so-called outline font using an outline vector, and can be applied to character display other than the karaoke device. .
