Patent ID: 8243211

Claim:
A method for generating a projected image comprising multiple image pixels, wherein for each color the method comprises: processing a pulse width signal and a light source select signal to generate modulation control data; receiving and processing image data to create pixel matrix control data and light source control data, the light source control data generated by processing a feedback signal, a power control signal and the modulation control signal; providing the light source control data to one or more light sources to selectively control output intensity of the light source on a frame by frame basis; providing the pixel matrix control data to one or more pixel matrixes to selectively control the opaqueness of the pixels of the one or more pixel matrix on a frame by frame basis; wherein for a particular frame, the output intensity of one of the one or more light sources is set at a level by means of the modulation control signal which will yield a desired color intensity for the image pixel with the highest color intensity and a corresponding pixel in the pixel matrix is controlled to pass therethrough generally all of the light from the light source.
