Multiple stage modulation projector display systems having efficient light utilization

Dual or multi-modulation display systems comprising a first modulator and a second modulator are disclosed. The first modulator may comprise a plurality of analog mirrors (e.g. MEMS array) and the second modulator may comprise a plurality of mirrors (e.g., DMD array). The display system may further comprise a controller that sends control signals to the first and second modulator. The display system may render highlight features within a projected image by affecting a time multiplexing scheme. In one embodiment, the first modulator may be switched on a sub-frame basis such that a desired proportion of the available light may be focused or directed onto the second modulator to form the highlight feature on a sub-frame rendering basis.

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.
