    摘要: In a learning process, first, images having different resolutions are obtained from a target region of the subject (S101). Further, the subject characteristic of the target region is obtained (S102). Then, the resolution conversion rules are learned from the images having different resolutions, and those are recorded to a storage device along with the subject characteristics (S103). When converting the resolutions, the resolution conversion rules learned for the corresponding subject characteristics are applied to each region of the original image so as to convert the resolutions of the original image.

    摘要: An image feature analyzing section performs an image feature analysis with respect to an input image to output an image feature vector. A parameter output section stores a plurality of image feature vectors and a plurality of parameters corresponding to the respective image feature vectors and outputs an original parameter value corresponding to an image feature vector. A parameter operation setting section determines contents of an operation of an illumination equation parameter, depending on a prescribed image conversion. A parameter operating section operates the original parameter value in accordance with a prescription of the parameter operation setting section, to obtain a new parameter value. An image generating section generates an output image based on the new parameter value.

    摘要: Pieces of white balance information indicating color features of a colored picture or picture blocks obtained by partitioning the colored picture are extracted from piece of picture data of the colored picture in an extracting unit. Whether or not a white region exist in the colored picture is judged in a white region judging unit according to the white balance information indicating the color features of the colored picture. When the existence of the white region is judged, a white balance coefficient is calculated in a white balance calculating unit to make the white region white. In contrast, when no existence of any white region is judged, a color distribution axis extending from an original point of a color space to a gravity center of the white balance information indicating the color features of the picture blocks from which pieces of white balance information corresponding to picture blocks of a high chromatic color or a uniform chromaticity are removed is detected in a color distribution axis detecting unit, and the white balance coefficient is calculated to set the color distribution axis to an achromatic color axis of the color space. Therefore, a white balance adjustment adapted to color features of each of colored pictures can be performed.

    摘要: The present invention relates to a method and apparatus applied to a widely-used and high-speed color conversion which is utilized in a color printer, a color display apparatus and the like, and provides a novel three-dimensional interpolation operation by use of a triangle-pole shaped interpolation unit-space. Input color signals R,G, and B are converted into lightness signal Y and chromaticity signals Cr, Cb which constitute a three-dimensional space. This three-dimensional space is dissected into rectangular parallelopipeds and is further divided into two prisms having base planes parallel to the chromaticity plane CrCb. A prism judging section 207 judges which of prisms an input color is involved in. There are provided a plurality of color conversion table memories 210.about.215 which store output values corresponding to input values constituting respective points of the prism and difference values of mutual output colors and further difference values of mutual difference values. Stored data in respective color conversion table memories 210.about.215 are weighted by lower-bit signals 205, 206 of the input color signals in multipliers 219, 220, 226, 227, and 230. Then, these data are added in adders 220, 221, 228, 229, and 231 so as to accomplish a linear interpolation using output values of six vertices which constitute the prism.

The image processing section includes: a varying intensity processing section which calculates a state of polarized light reflected from the object's surface; a reflection decision section which distinguishes a multi-reflection region in which incoming light is reflected twice from a recessed region from a once-reflected region in which the incoming light is reflected only once from the object's surface; and a mirror image search section which locates a pair of multi-reflection regions. Based on the pair of multi-reflection regions, the image processing section generates an image representing the recessed region on the object's surface.
