Abstract
Light projection systems and methods may comprise combining light from two or more projectors. Each projector may be controlled so that the combined light output of the projectors matches a target for the projected light. In some embodiments optimization is performed to generate image data and control signals for each of the projectors. Embodiments may be applied in image projecting applications, lighting applications, and 3D stereoscopic imaging.
Claims12
A method for generating signals for controlling a projector to display images according to image data, the projector comprising a first imaging element configured to provide modulated light to a second imaging element for further modulation by the second imaging element and a boost light configured to deliver additional illumination for modulation by the second imaging element, the method comprising:
- determining black levels of the images;
- simulating veiling luminance to determine a lowest perceivable luminance level in the image;
- and
- generating a signal, based on the determined black levels of the image, to supply highlights in the displayed images that have brightness greater than a peak brightness achievable by the first imaging element and to set the boost light at a level corresponding to the lowest perceptible luminance level.
