    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: 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: 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.

    摘要: A dynamic range is widened by effectively using an output range that is originally possessed by a solid-state image-capturing device, and an image having less color hue rotation is obtained.By using the fact that the margin until the amount of saturation electric charge is reached becomes large as a result of the amount of exposure being set to be low in a high sensitivity mode, an RGB signal having a wide dynamic range containing signal components of a subject on the high-luminance side is obtained. First, γ correction close to a power γ is performed and thereafter, the signal is color-space-converted into a luminance signal and color-difference signals. A non-linear compression process is performed on the luminance signal so as to be fit into predetermined gradations, and for the color-difference signals, color rotation is reduced using a power gamma and color-difference matrix clipping is performed.
