An adaptive color-temperature calibration system and method are disclosed. A chrominance generation unit generates a chrominance criterion according to an input pixel. A matrix generation unit generates a calibration matrix according to the chrominance criterion and a basis matrix. A color calibration unit then performs color-temperature calibration on the input pixel according to the generated calibration matrix, thereby generating an output pixel.

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.

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.

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).

Signals are provided which allow colors in a wider color range than predetermined standards, which can be handled by apparatus according to such predetermined standards. A primary color converter converts first color signals having primary color points in a wider color range than the primary color points according to BT.709 into second color signals based on the primary colors according to BT.709. A photoelectric transducer converts the second color signals into third color signals according to photoelectric transducer characteristics defined in a numerical range wider than a range from 0 to 1.0 of color signals corresponding to a luminance signal and color difference signals according to BT.709. A color signal converter converts the third color signals into a luminance signal and color difference signals. A corrector incorporated in the color signal converter corrects the color difference signals into color difference signals.

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.

A color conversion circuit converts a three-primary-color signal PS0 to a 5-color signal PS5, and includes (i) a color component extraction module that generates, by performing isochromatic conversion, a 7-color signal PS2 made up of 7 color components equivalent in terms of color to color components d1 through d5 of the 5-color signal PS5, and (ii) a matrix operation module that generates color components of the 5-color signal by performing linear combination of the color components of the 7-color signal. With this, it is possible to realize a color conversion circuit by which colors represented by a signal after conversion can be adjusted using intuitively-understandable parameters.

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.
