  • Publication number: 20210127098
    Abstract: A projection system includes a signal processor, a light source, an optical relay system, an adjusting member, and a DMD. The signal processor receives image data. The signal processor increases grayscale values of pixels of the image data. The optical relay system provides illumination light to the DMD for modulating to obtain projection light required for a projection image. The adjusting member reduces the luminous flux of the illumination light provided to the DMD when the grayscale values of the pixels of the image data are increased. A reduction ratio of the luminous flux of the illumination light matches an increase ratio of the grayscale values of the image data. The DMD modulates the adjusted illumination light according to the image data with increased grayscale values to generate the projection light required for the projection image.
