According to one embodiment of the present invention, a method of controlling an image projector comprising a multi-color laser source, projection optics, an image sensor, and a movement detection device comprises the projection of an image onto a display surface with the image projector. During projection, a movement signal generated by movement detection device is monitored, the movement signal indicating positional displacement of the image projector. A test pattern image is projected onto the display surface using the image projector, wherein the test pattern image projection is initiated as a function of the monitored movement signal. Thereafter, the projected test pattern image is captured from the display surface using the image sensor. A comparison of projected test pattern image data and captured test pattern image data is used to modify the manner in which subsequent images are projected to correct color distortions represented in the captured test pattern image.
