    摘要: Image data is encoded for distribution in a lower bit-depth format. The image data has a range that is less than a maximum range and is mapped to the lower bit depth format using a mapping such that a ratio of a range of the lower bit depth representation to a maximum range of the lower bit depth representation is greater than a ratio of the range of the image data is associated with lower bit depth representation. The metadata may be used downstream to reverse the mapping so that tonal detail is better reproduced.

    摘要: Apparatus and methods are provided to map out-of-gamut points to in-gamut points. Embodiments transform image data for presentation on a display or medium having a gamut different from that of the image data. Different mapping algorithms may be applied based in part on luminance of the points being mapped. Embodiments apply a reduced dataset representing a gamut boundary. Irregular gamuts may be accommodated

    摘要: Output image data for display on a target display having a target gamut is generated from first and second input image data. The first and second input image data may be color timed for display on different types of display. Chromaticity values in the output image data may be generated by interpolation using an interpolation parameter derived from the target gamut and gamuts associated with the first and second image data.

    摘要: In one embodiment the present invention includes a method that adjusts a display device according to a display environment. The method includes sensing the display environment of the display device and generating environment data that corresponds to the display environment. The environment data includes color data. The method further includes adjusting a color appearance model according to the color data, generating a control signal according to the color appearance model having been adjusted, and controlling a backlight of the display device according to the control signal. In this manner, a viewer perceives the images displayed by the display device in the manner intended by the content creator, because the adjustments to the color appearance model compensate for the viewer's physiological response to the display environment.
