Abstract
A control system for a projection display includes means for compensating for relative movement between a projection display and a projection surface and/or between a projected image and a viewer. The system may compensate for image shake. Movement may be detected optically, through motion or inertial detection, etc. The image may be compensated by modifying image properties such as resolution, by modifying an image bitmap, by moving a display engine or a display engine component, and/or by deflecting the projection axis, for example. According to an embodiment the projection display may include a display engine utilizing a laser scanner.
Claims42
A projection display comprising:
- a display engine operable to project an image;
- a sensor operable to generate a signal responsive to a motion;
- and
- a controller operable receive the signal from the sensor and responsively drive the display engine to project an image that includes compensation for the motion.
A method of compensating for image shake in a projection display comprising the steps of:
- detecting image shake;
- and
- projecting an image that compensates for the image shake.
A system comprising:
- a display operable to display an image;
- and
- a motion detection circuit operable to stabilize the image.
