    摘要: Techniques are provided to encode and decode image data comprising a tone mapped (TM) image with HDR reconstruction data in the form of luminance ratios and color residual values. In an example embodiment, luminance ratio values and residual values in color channels of a color space are generated on an individual pixel basis based on a high dynamic range (HDR) image and a derivative tone-mapped (TM) image that comprises one or more color alterations that would not be recoverable from the TM image with a luminance ratio image. The TM image with HDR reconstruction data derived from the luminance ratio values and the color-channel residual values may be outputted in an image file to a downstream device, for example, for decoding, rendering, and/or storing. The image file may be decoded to generate a restored HDR image free of the color alterations.

    摘要: The invention includes: an input section (5), for specifying a color gamut during photographing, which specifies a color gamut for reading information of a subject read by a reading section (2); and an input section (8) for specifying a color gamut for a display section (3) during displaying of the reading information by the display section (3). The display section (3) is capable of changing a color gamut by adjusting light intensities of respective different primary colors emitted from the display section (3). The input section (5) selects a color gamut which falls within the color gamut which the display section (3) can describe. The input section (8) selects the color gamut selected through the input section (5) as the color gamut for the display section (3).

    摘要: Provided is an image processing device. A first color space converting unit converts image data in an RGB colorimetric system, which has a color gamut wider than a color gamut of a liquid crystal panel into image data in an XYZ colorimetric system. A three-dimensional nonlinear color gamut converting unit performs conversion on tristimulus values of the XYZ signal. At this time, the image data is classified into four colors and converted respectively such that the first color is displayed in a color accurate to the inputted data, the second color is displayed such that saturation of the second color is increased, the third color is displayed using a color gamut of a predetermined range out of the color gamut of the liquid crystal panel, and the fourth color is displayed in a color corresponding to a boundary of the color gamut of the liquid crystal panel.
