[Technical field to which the invention belongs]
The present invention relates to a karaoke apparatus that displays a mood video on a display during performance of karaoke accompaniment music, and in particular, selects a mood video program suitable for a search method selected when a user searches for a desired song from a mood video database. It relates to the display method.
[0002]
BACKGROUND OF THE INVENTION
In a karaoke device, the mood image displayed on the display when performing accompaniment music of a karaoke song is recorded on a CD-ROM etc. for a common communication type karaoke device and used for each song. It is turning. However, mood video is now one of the pleasures of karaoke, and making this mood video rich and rich in content leads to a significant increase in karaoke merchandise. For this reason, various ideas have been devised.
[0003]
For example, a mood image to be used for each song is determined in advance from such a shared mood image, and there is a method in which a fixed mood image is always displayed when the song is played. There is also a method of randomly selecting and displaying mood images that match the music genre of the music.
In addition, there are some karaoke companies that perform location according to the content of music or make original singers appear, and produce and supply dedicated video programs for each song. Furthermore, a method of accepting submissions of works produced by amateur videographers and converting them to video programs has been put into practical use. In addition, a method in which a karaoke user selects from these various video programs has been developed.
[0004]
On the other hand, there are various karaoke music selection tools. For example, there is a search-type karaoke remote control device put into practical use by the present applicant. This karaoke remote control device has a variety of search methods such as searching at the time of popularity as well as searching for song titles and singer names.
[0005]
Therefore, the present inventor has considered that it is convenient to automatically select from a number of video programs suitable for the user's preference and feeling without requiring any further operation by the user. For that purpose, we focused on how the user selected the song. Even if I arrived at the same song, I thought that the degree of fondness for that song would appear in the difference in approach.
[0006]
For example, a user who selects a song using the “song name” search is thought to have a strong commitment to the song itself, and will be pleased if the mood video created for that song is displayed.
On the other hand, the user who selects the song by searching for “singer name” will be very pleased if the mood video in which the singer himself appears is displayed because the original singer may be preferred.
Or, users who have selected songs by searching for “that time” can be thought of as remembering the era in particular, so if the TV programs, people, and news videos that were of interest at that time were displayed as mood images, it would be exciting. Let's go.
Alternatively, if the user selects a song by searching for “new music”, displaying the promotion video as a mood video not only rejoices the user, but also increases the advertising effect.
