IMAGE DISPLAY DEVICE, METHOD, AND PROGRAM

摘要

It is an object of the present invention to make an act of viewing an image interactive and further enriched. A microphone 18 inputs a voice signal of a voice uttered by a viewer who is viewing a display image displayed on a display portion 17, and causes the voice signal to be stored in a buffer 19. A voice recognition portion 20 identifies at least one word from the voice uttered by the viewer based on the voice signal, and acquires them as a keyword. A counter 21 calculates the number of incidences of the keyword. A display driver 16 causes information including a keyword having a number of incidences that exceeds a threshold value or information derived from the keyword to be displayed together with the display image displayed on the display portion 17.
