Highlighting an object displayed by a pico projector

1. An apparatus for projecting an image on a surface, the apparatus comprising:

a controller for receiving and decoding an image signal representative of the image to be displayed;

a light engine for projecting the decoded image signal on the surface; and

a panel driver connected to the controller for driving the light engine based on control signals received from said controller, said panel driver operating in a first normal mode that drives the light engine within a preset power range and a second overdrive mode that drives the light engine at a power level above the preset power range during a portion of a scan period causing information displayed during the second overdrive mode to appear highlighted, wherein said controller skips frames of the decoded image signal and replaces the skipped frames with frames including only information to appear highlighted.

2. The apparatus of claim 1 , wherein said controller decodes a control signal within the image signal, the control signal instructing said controller to cause said panel driver to operate in said second overdrive mode.

3. The apparatus of claim 1 , wherein said controller receives a control signal from a user input device, the control signal instructing said controller to cause said panel driver to operate in said second overdrive mode.

4. A method for highlighting information within an image displayed by a projection unit, said method including:

receiving a video signal;

decoding the video signal;

controlling a panel driver to drive a light engine within a predefined power range to display the video signal;

causing the panel driver to enter an overdrive mode driving the light engine at a power level above the preset power range for a period of a scan of the video signal at which information to be highlighted is displayed;

skipping frames of the video signal; and

replacing the skipped frames with frames including the information to be highlighted.

5. The method of claim 4 , further comprising the step of receiving a control signal instructing a controller to cause the panel driver to enter the overdrive mode.

6. The method of claim 4 , wherein a control signal is included within the video signal, the control signal causing the panel driver to enter the overdrive mode.

7. An apparatus for projecting an image on a surface, the apparatus comprising:

means for receiving and decoding an image signal representative of the image to be displayed;

means for projecting the decoded image signal on the surface; and

means for driving the means for projecting based on control signals received from said means for receiving and decoding, said means for driving operating in a first normal mode within a preset power range and a second overdrive mode at a power level above the preset power range during a portion of a scan period causing information displayed during the second overdrive mode to appear highlighted, wherein said means for receiving and decoding skips frames of the decoded image signal and replaces the skipped frames with frames including only information to appear highlighted.

8. The apparatus of claim 7 , wherein

said means for receiving and decoding decodes a control signal within the image signal, the control signal instructing said means for receiving and decoding to cause said means for driving to operate in said second overdrive mode.

9. The apparatus of claim 7 , wherein

said means for receiving and decoding receives a control signal from a user input device, the control signal instructing said means for receiving and decoding to cause said means for driving to operate in said second overdrive mode.
