The image data is read out from the RAM 15, and the tone correction is performed for the readout image data in the tone correction circuit 35.

Abstract: 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, ? correction close to a power ? 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.

Abstract: A method of evaluating halo artifacts is described herein. The method utilizes a pattern of color patches, a color space and color difference metrics to analyze color changes which correlate to the amount of halo. The pattern of color patches is utilized in the CIE L*a*b* color space to determine an area of patch unaffected by halo of the pattern of color patches. After the area of patch unaffected by halo is determined, a Reference Value is computed by averaging the CIE L*a*b* color for the area of patch unaffected by halo. Then an Artifact Value is calculated either by averaging the CIE L*a*b* color for the area outside the area of patch unaffected by halo but before the margin or by averaging the CIE L*a*b* color on the edge of the patch. Once these values are determined, the halo quantity is calculated.

In an image processing unit (40), data color-corrected for each output device by a color image device correction processing unit (41) is converted to output reference color space data such as e-sRGB or e-sYCC, a directory is prepared in a flash memory (50) by a data saving processing unit (42), and the data corrected to each image device is saved into the prepared directory. Thus, when using the image data coded in the standard color space, an image data group converted to color characteristics suitable for specific purposes is efficiently managed.

Abstract: A printer device and a picture printing method is disclosed, in which, if the gradation for cyan is to be represented, an ink C′ of low concentration is superimposed to represent the low gradation area. This cyan ink is used in combination with a high-concentration blue ink B and a high-concentration green ink G to represent a high gradation area. In representing the high gradation area, the emitting proportions of the high-concentration blue ink B and the high-concentration green ink G are changed to enable the color hue in the high gradation area to be varied delicately to improve color reproducibility.
