Light array projection and sensing system
First Claim
1. A light array device, comprising:
- a control unit; and
an integrated array pack, the array pack including a plurality of light emitters, a multi-image film having a plurality of individual images, and a plurality of optical elements, wherein the array pack is in communication with the control unit such that the control unit operates the array pack to project at least one illuminated image.

Abstract
A low cost, light projection and sensing system that projects an image onto a display surface using an array of light emitters. The system or device has an integral sensing capability of the display surface using light sensors. Both the emitters and sensors are coupled to a control unit. The device modifies the light-projected image and sensor view region with its control unit. The device projects an animated overlaid image or large tiled image of photographic resolution. In at least one embodiment, a projection device may create smooth animation of its projected image by varying the brightness of one or more illuminated images within its generated video frames. Computer implemented methods are utilized for light emitter activation and brightness control.

15. A computer implemented method for presenting video frames using a light array device comprising a plurality of light emitters that each generate one of a plurality of converging beams of light, the method comprising:
-
activating at least one light emitter to project a first video frame from the light array device, wherein the first video frame is projected to a focal point and is comprised of an at least a first illuminated image; and subsequently activating one or more other light emitters to generate one or more subsequent video frames from the light array device, wherein the subsequent video frames are projected to the focal point and are comprised of an at least second illuminated image. - View Dependent Claims (16, 17, 18, 19)
