Abstract
A communication configuration capable of acquiring communication data within an image without need of a high precision synchronization process is realized. A transmission apparatus has a projector outputting an image, and an output image generation section generating the image output from the projector. The output image generation section generates a communication data image that records communication data, and the projector outputs a viewing image and the communication data image by setting an output time period of the communication data image to be longer than an output time period of each of sub-frame images that configure the viewing image. A receiving apparatus detects an event which is a luminance change equal to or greater than a prescribed threshold, receives input event information including a pixel position and occurrence time of an event occurrence pixel, detects a communication data image contained in the projected image on the basis of an event occurrence interval, and acquires communication data from the communication data image.
