Abstract

An image projection module within a housing accessory is operative for causing selected pixels in a raster pattern to be illuminated to produce an image at different image planes of VGA quality. A personal media player is connected to the housing accessory and the image projection module to supply image signals for the image to be projected.

Claims (16)

1. An arrangement for projecting an image, comprising:

a) a housing accessory having a window;

b) an image projection module in the housing accessory for sweeping a pattern of scan lines through the window, each scan line having a number of pixels, and for causing selected pixels to be illuminated, and rendered visible, to produce the image; and

c) a personal media player having a front side wall and a rear side wall and being connected to the housing accessory and the image projection module to supply image signals for the image to be projected by the module on one of the side walls.

2. The arrangement of claim 1 , wherein the housing accessory has a compartment in which the personal media player is received.

3. The arrangement of claim 2 , wherein the compartment is upwardly open, and wherein the personal media player is received in the compartment with an upright orientation.

4. The arrangement of claim 1 , wherein the personal media player includes a display screen mounted thereon, and wherein the module projects the image with a size larger than the display screen.

5. The arrangement of claim 1 , wherein the accessory has a dock connector for electro-mechanical connection with another dock connector on the personal media player.

6. A method of projecting an image, comprising the steps of:

a) sweeping a pattern of scan lines through a window of a housing accessory using an image projection module, each scan line having a number of pixels, and causing selected pixels to be illuminated, and rendered visible, to produce the image;

b) using image signals for the image to be projected using a personal media player having a front side wall and a rear side wall; and

c) connecting the personal media player to the housing accessory and the image projection module, and projecting the image on one of the side walls.

7. The method of claim 6 , and the step of receiving the personal media player in a compartment of the housing accessory.

8. The method of claim 7 , and configuring the compartment to be upwardly open, and wherein the personal media player is received in the compartment with an upright orientation.

9. The method of claim 6 , wherein the personal media player includes a display screen mounted thereon, and the step of projecting the image with a size larger than the display screen.

10. The method of claim 6 , wherein the connecting step is performed by electro-mechanically connecting a dock connector on the accessory with another dock connector on the personal media player.
