摘要： A gradation-correcting curve to correct a gradation of an input image is generated. Gradation correction based on the gradation-correcting curve is made to a boundary pixel of a color-reproduction space at the same saturation as that of a target lattice point and at a hue of the target lattice point. An equal-saturation line is set by using the boundary pixel of the color-reproduction space after the gradation correction. A saturation-correction amount of the target lattice point is decided based on the gradation-correcting curve and the equal-saturation line.

摘要： In case of an image region having a property of abrupt changes in luminance and tint, even when a region made up of pixels having luminance values and tint levels similar to those of one point designated by the user is extracted as a correction region with reference to the user designated point, it is difficult to extract a region to be corrected without omission. To solve this problem, a user instruction indicating a point inside or near an image region which is to undergo correction is input, and a plurality of origin pixels corresponding to start points of region expansion are set in a region which includes the input point and has a predetermined size. The region expansion is executed from each origin pixel, and a correction region is decided according to the result of the region expansion.

摘要： An embedded system of a digital camera or printer has limited available memory resources. Under such environment, devices are required to detect a red-eye region from a high-resolution image. To solve this problem, an input image is divided into band images each including a predetermined number of lines, so that an overlap area exists between neighboring band images, and candidate pixels which form an image region exhibiting poor color tone are extracted for each band image. The band image which is to undergo characteristic amount determination is determined based on the position of the candidate region which includes the candidate pixels in the overlap area.
