An image processing apparatus has a stochastic resonance processing unit executing a stochastic resonance processing to obtain a result. The result corresponds to a result that is calculated in a case where each of a plurality of pixel signals constituting reading image data is added noise and subjected to a binary processing and a plurality of results obtained by parallelly performing above step are synthesized and the parallel number is infinite. The stochastic resonance processing unit sets, with regard to a pixel signal as a processing target among the plurality of pixel signals, at least one of a strength of the noise and a threshold value used for the binary processing based on a pixel signal of the input image data corresponding to the pixel signal.

In order to reduce a density difference that appears when printing whose execution number of scan operations is changed is performed, a CPU acquires a plurality of color conversion LUTs; the CPU performs printing of each of normal portions of color patches using a reference LUT and performs printing of each of hitch portions of the color patches using a corresponding one of mutually different color conversion LUTs; the CPU allows a color patch having a small density difference to be input as a selection result; the CPU identifies a color conversion LUT corresponding to the selection result; and the CPU designates the color conversion LUT corresponding to the selection result as a color conversion LUT for the hitch portion.

A color processing apparatus includes first, second, and third acquiring units. The first acquiring unit acquires first color data indicating association among first-space color in a first space, second-space color obtained using a reading unit reading measurement images having different first-space colors, and third-space color obtained by converting the second-space color through a predetermined transformation model. The second acquiring unit acquires second color data indicating association between the first-space color and the third-space color obtained using a measuring unit performing color measurement on some of the specific-color measurement images containing a specific color in the first space and included in the measurement images. The third acquiring unit acquires third color data indicating association between the first-space color and the third-space color obtained by converting the first-space color through a transformation equation obtained from the first and second color data. The conversion is performed on the other specific-color measurement images.

The present disclosure relates to an information processing apparatus, an information processing method and a program, and a recording medium that can generate graphics in colors in a predetermined dynamic range from the data of graphics of colors in a plurality of dynamic ranges. A processor identifies an SDR PDS that is an information item of a color in the SDR available for the graphics, an HDR PDS that is an information item of a color in the HDR available for the graphics from a graphics stream including the SDR PDS, and the HDR PDS, and a segment_type used to identify the SDR PDS and the HDR PDS on the basis of the segment_type. A CLUT management unit generates the SDR graphics on the basis of the SDR PDS identified by the processor. The present disclosure can be applied, for example, to a reproducing device.

Examples of a method and a system for configuring an imaging system are described. These examples involve obtaining a random sample of area coverage representations and grouping these by an estimated color, such as a colorimetric value. In each group a selected area coverage representation is determined with respect to one or more imaging attributes. A color gamut based on the random sample and the selected area coverage representations are used to generate a color mapping from an input color space to an area coverage representation space for use by the imaging system.

A color-measuring apparatus includes an imaging unit that images a test pattern and obtains image information of the test pattern, a reference color-measuring unit that color-measures the test pattern and obtains a reference color measurement value of the test pattern, and an amending unit that obtains the color measured result of the test pattern in a narrow range in at least one direction in comparison with a measuring range for obtaining the reference color measurement value by the reference color-measuring unit based on at least the image information and the reference color measurement value.

An image processing apparatus includes a processing unit that converts first input image data for a first region and second input image data for a second region to reduce a difference between first region recorded image density and second region recorded image density, and generates dot position data of a dot to be generated in each of the first and second regions based on the dot data after the conversion processing. The acquisition unit acquires edge information indicating a first object pixel edge of an image pixel for the first region and a second object pixel edge of an image pixel for the second region. Based on the acquired edge information, conversion and generation processing are performed in such a manner that a color signal of an edge pixel is increased/reduced to a degree lower than a degree to which a color signal of a non-edge object pixel is increased/reduced.

An image forming apparatus includes a forming unit configured to form a set of reference patches corresponding to different density regions through an image forming unit while making the reference patches correspond to screen types, an input unit configured to input a comparison result between each of the reference patches and criterial patches having densities as criteria at each of the screen types, and a generation unit configured to generate information for correcting a density of an image formed by the image forming unit at each of the screen types by using the comparison result input by the input unit, wherein the information generated by the generation unit for correcting an image in a highest density region from among the density regions is commonly generated according to the comparison result input with respect to each of the reference patches formed at each of the screen types.
