Portable projector background color correction scheme

A method of controlling an image projector comprising a multi-color laser source, projection optics, an image sensor, and a movement detection device, the method comprising:

• projecting an image onto a display surface using the multi-color laser source and the projection optics of the image projector;
• monitoring a movement signal generated by the movement detection device, wherein the movement signal is indicative of positional displacement of the image projector;
• projecting a test pattern image onto the display surface using the multi-color laser source and the projection optics, wherein the test pattern image projection is initiated as a function of the monitored movement signal;
• capturing the projected test pattern image from the display surface using the image sensor;
• and
• utilizing a comparison of projected test pattern image data and captured test pattern image data to modify the manner in which subsequent images are projected using the multi-color laser source and the projection optics of the image projector to correct color distortions represented in the captured test pattern image.
