Description

  The present invention relates to an image display device capable of simultaneously reproducing audio data associated with displayed still image data when executing a slide show of still image data recorded on a recording medium.

  In recent years, for example, an image display device (for example, a liquid crystal television) is used for digital signage (electronic signage) in an in-store advertisement or the like.

  For example, a retail store or the like is not connected to a network or the like, and the image display device can be used for digital signage standalone, and still image data is displayed in a slide show. For this reason, the image display device is also required to have a function of reproducing audio data. However, simply displaying a slide show while reproducing audio data in a loop does not match the audio data being reproduced with the displayed still image data. A situation can occur.

  In order to solve such a problem, there has been proposed an apparatus that indirectly associates audio data with still image data and switches audio data at the start of display of each still image data during a slide show. (For example, refer to Patent Document 1).

  In the apparatus described in Patent Literature 1, attached information associated with each piece of image information related to slide show display control is extracted, and corresponding event information is determined from the event information database based on the attached information. Then, music information corresponding to each slide show is determined based on the event information, and the music determined corresponding to the slide show is output during the slide show.

  In the user setting data, when the association information between the still image data and the audio data is set by the user, the audio data input unit 30 stores the (predetermined) audio data associated according to the association information of the user setting data. The data is output to the audio data reproducing unit 31. The audio data reproduction unit 31 reproduces audio data, and the audio output unit 32 outputs the audio reproduced by the audio data reproduction unit 31 simultaneously with the still image displayed by the still image output unit 22.

  Here, MP3 (MPEG Audio Layer-3), AAC (Advanced Audio Coding), or the like can be adopted as a file format of the audio data input to the audio data input unit 30. As long as it is possible, it should not be specified.

  Next, the association setting between still image data and audio data will be described with reference to FIG. FIG. 2 is an explanatory diagram illustrating an example of setting the association between still image data and audio data. When the recording medium is connected to an image display device (more specifically, the recording medium input / output interface 10), the still image data read from the recording medium by the recording medium data input unit 11 is converted into the still image image data input unit 20. The still image output unit 22 displays a list of still image data as thumbnails.

  For example, it is assumed that a list of still image data 50a and 50b displayed as thumbnails on a GUI (Graphical User Interface) can be displayed and operated by the user himself / herself by remote control operation of the image display device. The still image output unit 22 displays a sub-window 60 of a list of audio data by a predetermined key operation during selection of one still image data. The user selects suitable audio data for the selected still image data, and performs a predetermined key operation to complete the association between the still image data and the audio data.

  In FIG. 2, “audio data 1.XXX” and “audio data 2.XXX” are displayed in the audio data list sub-window 60, and for example, a title related to audio data is displayed in XXX. Is displayed.

  The linked still image data and audio data are filed in a predetermined format (for example, a text file) by the user setting data creation unit 40, and the user setting data created by the user setting data creation unit 40 is user setting data. The data is output to the user setting data input / output unit 12 in the recording medium input / output interface 10 by the output unit 41, and is recorded on the recording medium by the user setting data input / output unit 12.

  For this reason, for example, even if the connection between the image display device and the recording medium is released, the user setting data can be read from the recording medium when the connection is made again, and the troublesome work such as resetting the user setting data is possible. Thus, it is possible to link still image data and audio data suitable for the user in a stand-alone manner without causing any other devices and connecting other devices.

  Note that instead of the still image output unit 22 outputting a list of audio data, for example, the audio output unit 32 outputs the touched portions of the audio data in order, thereby allowing the user to select suitable audio data. May be.
