Abstract
A system, method and program product for enhancing video content being projected by a video projector. A video projector is disclosed having a projection system for projecting video content onto a surface; a camera for capturing image data from the surface; an analysis system for analyzing captured image data; and a correction system for enhancing the video content being projected onto the surface based on the analysis of the captured image data.
Claims19
A video projector, comprising:
- a projection system for projecting video content onto a surface;
- a camera for capturing image data from the surface;
- an analysis system for analyzing captured image data, wherein the analysis system injects test pattern frames at various intervals into a moving video feed and analyzes captured test patterns from a resulting projected moving video;
- and
- a correction system for enhancing the video content being projected onto the surface based on the analysis of the captured image data.
A program product stored on a non-transitory computer readable storage medium, which when executed by a computer system, enhances video content projected by a video projector onto a surface, and comprises:
- program code for causing a test pattern to be projected by the video projector;
- program code for inputting capturing image data from a camera directed at the surface;
- program code for analyzing captured image data;
- program code for enhancing the video content being projected onto the surface based on the analysis of the captured image data;
- and
- program code for causing a visual cue to be projected on the surface in response to a detected problematic area requiring manual intervention.
A method for enhancing video content being projected by a video projector onto a surface, comprising:
- projecting a test pattern onto the surface using the video projector, wherein the test pattern is projected in a semi-transparent manner along with the video content;
- capturing a test pattern image using a camera directed at the surface;
- analyzing the test pattern image;
- and
- enhancing the video content being projected onto the surface based on the analysis of the test pattern image.
