  • Publication number: 20110157488
    Abstract: A projector of enhanced color visual output and the method of enhancing the color vividness of a projector output, wherein the projector has a program of instructions stored within its memory to perform image data analysis. The image data analysis includes RGB level detection and histogram calculation. The projector dynamically compares these data, using a waveform selection algorithm, to dynamically select an appropriate waveform from a waveform data table stored in the memory. As a result, the projector constantly changes to use a driving waveform for the light source that is appropriate for the content of the projected image. By using a dynamic waveform to vary the light source, the brightness of selected color region is enhanced to improve vividness of color on a projected image.
