An information display apparatus performs a visual light communication and superimposes light source information transmitted from a light source onto images captured in time sequence for display on a screen. The information display apparatus includes an imaging section for capturing an image in an imaging range, a cache memory sequentially caching the light source information transmitted from the light source in the image, a priority level setting section for setting a higher priority to the light source information, cached in the cache memory, in order starting from a light source closest to a current imaging range, and a communications information processing section for deleting the light source information cached in the cache memory in order starting from light source information having the lowest priority level.
