    摘要: The method, system and apparatus embodiments of the present invention provide for rendering original images having high dynamic range into display images having lower dynamic range while retaining a visual quality of rendered images comparable to the original or reference images. Tone-mapping parameters are applied to the display images and are iteratively adjusted in order to reduce the differences between the conditioned original image and the conditioned display image.

    摘要: A method for extending bit-depth of display systems. The method includes creating pseudo-random noise from human visual system noise. When applied to the image data, the noise causes spatiotemporal dithering. The pseudo-random noise is combined with image data, producing noise-compensated image data. The noise-compensated image data is them quantized.
