Abstract: An image processing apparatus obtains image data that is defined as a first color gamut, transforms the image data into image data that is defined as a second color gamut, using color transformation information, and when, as a result of transformation, a first pair of color values included in the image data is transformed into a second pair of color values that have a color difference that is not perceived as different colors, generates second color transformation information such that the first pair of color values is transformed into a third pair of color values that have a color difference that is perceived as different colors as a result of transformation using the second color transformation information. A saturation difference of the third pair of color values is larger than a saturation difference of the second pair of color values.

Abstract: The present technique relates to a surgery system, a surgery control device, a control method, and a program that allow a practitioner to easily operate a device during surgery. A surgery region is captured to acquire a surgery image that is an image of the surgery region, and a display image is output on the basis of the surgery image. With at least one of a surgical instrument and a hand reflected on the surgery image as an operation body, a predetermined instruction operation by the operation body is accepted on the basis of an image of the operation body in the surgery image. The present technique is applied to an endoscope system and a microscope surgery system.

Abstract: If a correction unit corrects a conversion unit configured to convert a color gamut of input image data into a color gamut of a device configured to output the image data, a generation unit generates image data having undergone color gamut conversion from the input image data using the corrected conversion unit. In the image data having undergone the color gamut conversion by the corrected conversion unit, a color difference in the image data having undergone the color gamut conversion by the conversion unit is expanded.

A voice recognition unit counts, through voice recognition, the remaining number of surgical tools existing in the body of the patient and used for a surgical operation, an image recognition unit counts, through image recognition, the remaining number of the surgical tools existing in the body of the patient, and a presentation control unit presents a predetermined warning when a difference arises between a first remaining number counted through the voice recognition and a second remaining number counted through the image recognition. The present disclosure can be applied to surgical systems.

Abstract: In an image processing apparatus for encoding image data and a method of controlling the same, whether an attribute of each of a plurality of areas in image data corresponds to an edge in an image based on the image data is determined, and one of a plurality of sub-sampling processes is selected according to the determination for each of the plurality of areas. Note that the plurality of sub-sampling processes can sub-sample color difference components of each of the plurality of areas by different processes. By the sub-sampling process selected as that corresponding to each of the plurality of areas, each of the plurality of areas is sub-sampled to encode the image data.

Abstract: Differences in color change due to bronze colors and the optical interference state related to bronzing are suppressed among multiple print modes. The blue primary color “Blue” in the standard RGB gamut is mapped to a point (color) that has moved in the clockwise direction, and that color is taken to be the primary color “Blue-s” in the Standard mode gamut. As a result, when an observer observes this color, the color shifted in the counter-clockwise direction is perceived as a color of the same hue as the primary color “Blue-f” in the Fine mode gamut, suppressing the difference in perceived color between the Fine mode and the Standard mode.

Abstract: A check pattern is printed which makes it possible to detect, with high precision, individual patterns corresponding to nozzles of a print head of an inkjet printing apparatus. More specifically, after an alignment mark is printed, ejection of an ink from the nozzles is stopped for a certain time. Because of this stoppage time, the concentration of a coloring material of the ink ejected from the nozzles increases, whereby the optical density of an analysis pattern which is printed later can be increased. In this manner, a scanner can read, with high precision, the patterns corresponding to the nozzles.

Abstract: In an inkjet printing apparatus, the colors of ink dots are controlled to make it possible to change the colors of an image to be printed. More specifically, ink temperatures, ink permeation speeds, and the capillary occupancy rates of inks in a print medium are used to control a permeation area formed by performing printing with preceding cyan and subsequent magenta, thereby controlling the colors realized by the inks which are ejected in an overlapping manner.

Abstract: In an overlapping head including a plurality of recording head chips overlapped to each other, a color shift can occur between a color recorded by an overlapping region and a color recorded by a non-overlapping region, which cannot be corrected by a density correction using head shading or the like. To correct such a color shift, a test pattern is recorded by the overlapping region and the non-overlapping region and colors of the recorded test pattern are measured. Color correction data to be used in correction of colors of an image to be recorded is generated based on a result of the measurement of the colors.

Abstract: In image processing, it is possible to suppress density fluctuation and keep graininess low as well as obtain a good balance of the processing load. More specifically, when dividing multi-valued data and generating two-pass multi-pass printing data, divided multi-valued data that is common to the two passes is generated in addition to the divided multi-valued data for each of the two passes. Moreover, quantized data of that common multi-valued data is reflected on the quantized data for each pass. Furthermore, when generating quantized data, a process of generating common data by the aforementioned data division, or a process of performing quantization first without dividing the multi-valued data and then dividing the quantized 2-pass data is selectively performed according to the printing position on printing medium.

Abstract: Uneven glossiness is effectively suppressed between areas where light inks are mainly used and areas where dark inks are mainly used. The gloss is raised in areas where dark cyan ink C is used. In other words, the application amount of second clear ink applied by after application printing is set to 32% at primary cyan (grid point 16) to equalize the gloss with areas where light cyan ink LC is used. Also, the application amount of first clear ink applied by common printing is set to 32% in a highlight portion (grid point 8) to equalize the gloss with the maximum gloss reached using dark cyan ink C. In so doing, it is possible to keep the gloss nearly constant over the entire range from white to cyan, or in other words, suppress uneven glossiness.

Abstract: Provided is an image processor and image processing method that are capable of suppressing both density unevenness and graininess that occur due to deviation of the printing position of dots that are printed by a plurality of relative movements (or a plurality of printing element groups). In order to accomplish this, the dot overlap rate of an image characteristic in which density unevenness stands out is made higher than the dot overlap rate of an image characteristic in which other defects stand out more than the density unevenness. By doing so, it is possible to suitably adjust the dot overlap rate according to an image characteristic, and to output an image having no density unevenness or graininess.

Abstract: A user is prompted to select one coating mode from a plurality of coating modes having different methods of applying a transparent recording agent. If the selected coating mode is not available in a preset print setting, a print setting available in the selected coating mode is presented to the user, and the set print setting is changed.
