A product includes a first area and a second area. Each area includes areas having a first optical property and areas having a second optical property. The areas having the first optical property and the areas having the second optical property are arranged under a specific rule. In the first area, convex portions whose height is equal to or smaller than a predetermined height or no convex portions are formed. In the second area, convex portions whose height is larger than the predetermined height are formed.

Product and method of manufacturing product

An image processing apparatus includes one or more computer-readable storage media, and one or more processors, wherein the one or more processors and the one or more computer-readable storage media are configured to: acquire image data acquired by capturing an image of an object, acquire distance information about a distance from an imaging apparatus, by which the captured image of the object is captured, to the object, acquire an optical profile representing an attribute of an image reflected on a surface of the object based on the image data and the distance information, and evaluate a state of the surface of the object based on the optical profile.

Image processing apparatus, image processing method, and storage medium

An image processing apparatus includes an obtainment unit configured to obtain first image data obtained by capturing an image of an object, a generation unit configured to generate second image data representing a second image by performing conversion to maintain a specific gradation in a color saturation range in a case where a hue or color saturation of a region of interest in a first image represented by the first image data is converted according to a characteristic of a display unit, a conversion unit configured to perform conversion on the first image and the second image according to the characteristic of the display unit, and a display control unit configured to display the converted first image and the converted second image together on the display unit.

A first obtaining unit obtains two images obtained by capturing images of an inspection target object under different capturing environments with different illumination conditions inputted by a user. A second obtaining unit obtains area information that specifies two types of areas set by the user regarding an area in each image. The two types of areas include a reference area serving as a reference for comparison between the areas and a comparison target area serving as a target of comparison. A converting unit generates color conversion parameters for carrying out color conversion such that a color value of the reference area in one image coincides with a color value of the reference area in the other image. A deriving unit derives a color difference between the reference area and the comparison target area regarding each of the two images.

The image forming apparatus is configured to obtain subsurface scattering characteristic data indicating the subsurface scattering characteristic of a reproducing target, and determine the laminated structure of the layer of the scattering material based on the subsurface scattering characteristic data. The image forming apparatus is configured to then form an image corresponding to the layer of the scattering material based on the determined laminated structure of the layer of the scattering material.

Image forming apparatus and image forming method

A color conversion apparatus to output image data to a printer obtains roughness data to indicate the roughness of each pixel in an image expressed by the image data, derives a reduction ratio of a color gamut in each pixel according to a roughness of each pixel in the roughness data, changes color gamut data indicating for the printer on a substantially flat surface according to the derived reduction ratio to derive color gamut data in each pixel, and then performs color conversion on each pixel in the image data using the derived color gamut data.

Color conversion processing apparatus and color conversion processing method

Capturing conditions and capturing of an imaging apparatus, which captures a plurality of color patches displayed on a monitor, are controlled. Imaging data is inputted from the imaging apparatus. Measurement values of the plurality of color patches are calculated from the imaging data using color conversion characteristics corresponding to the capturing conditions. First capturing conditions used at start of the capturing for the calculation of measurement values based on the imaging data captured by the imaging apparatus using initial capturing conditions. After the capturing for the calculation of measurement values is started, when the imaging data is input, it is determined whether or not perform the capturing by changing the capturing conditions.

Color processing apparatus and method therefor

This invention makes it possible to provide a technique for suppressing a decrease in resolution of a sensed image even when an image sensor on which solid-state image sensing elements with different sensitivities are arranged is used. A demosaic unit obtains a color component of a given pixel, sensed at the first sensitivity, by performing interpolation calculation using color components of pixels each of which is adjacent to the given pixel and is sensed at the first sensitivity. The demosaic unit also obtains a color component of a given pixel, sensed at the second sensitivity, by performing interpolation calculation using color components of pixels each of which is adjacent to the given pixel and is sensed at the second sensitivity.

Image sensing using solid-state image sensing elements

The analysis and evaluation techniques of a gamut mapping technique, which can reflect the determination result of the quality of gamut mapping in the gamut mapping technique, are demanded. Hence, a color distribution information file and image file are loaded, initial 3D object data is generated based on color distribution data, and initial image object data is generated based on image data. The image object data and 3D object data are displayed on a monitor. When the user inputs a message, a process corresponding to the input message is executed, and the updated image object data and 3D object data are displayed on the monitor.

Color information processing apparatus and method

Color values of a color space are stored in a color correction table. A smoothing process is performed on achromatic color values to remove artifacts and prevent image degradation caused by the correction process. The color values obtained from the smoothing process may also be adjusted for projection onto the achromatic axis.
