摘要： The present invention has been made in view of the foregoing, and an object thereof is to provide an information processing device capable of appropriately determining a necessity of the ultrasonography even when a high-density mammary gland area exists in a narrow area. The present invention provides an information processing device comprising: a mammary gland area extractor configured to extract a mammary gland area in a mammography image; a mammary gland pixel detector configured to detect a mammary gland pixel in the mammary gland area; and a mammary gland density calculator configured to calculate a mammary gland density based on a ratio of the mammary gland pixels to the mammary gland area, wherein the mammary gland area is a narrower area than an entire breast in the mammography image.

摘要： Technology is known for correcting the gradation characteristics of an input image signal in accordance with the characteristics of a display device, but a correction that is suitable for the usage of the display device is desired. Provided is an image processing apparatus including a first gradation converting section that converts a gradation of an image signal input thereto; a sharpening process section that performs a sharpening process on the image signal after the gradation has been converted by the first gradation converting section; a second gradation converting section that converts the gradation of the image signal after the sharpening process has been performed; and a display control section that displays an image indicated by the image signal after the gradation has been converted by the second gradation converting section, in a display device.

摘要： The visibility of a display device under colored ambient light is improved. There is provided an image processing system for converting a color space represented by color components of image data. The image processing system includes a color space converter configured to correct the color components of the image data by converting the color space such that, with respect to particular color components in user-perceived color gamut widened by influence of chromatic adaptation caused by ambient light, the influence is maintained and such that, with respect to particular color components in user-perceived color gamut narrowed by the influence, the influence is canceled; and a display unit configured to display, as an output image, the image data using the corrected color components.

摘要： Provided is an image processing device, image display device, and program that allow an image captured by an imaging device not having a vibration suppression function or an image whose vibration has been suppressed incompletely to be displayed on a display device with the vibration suppressed. The image processing device includes a motion estimator configured to estimate the amount of motion of an object between a first image and a second image later than the first image and a motion compensator configured to perform a conversion process on the second image so that vibration of the object between the first image and the second image is suppressed, on the basis of the amount of motion of the object. The motion estimator has a first estimation mode in which the amount of motion of the object is estimated in a predetermined search area and a second estimation mode in which the amount of motion of the object is estimated in a larger area than the search area in the first estimation mode.

摘要： A technique to remove fog from an image more appropriately has been called for. An image processing system is provided, including: a high saturation pixel extracting unit that extracts, from one frame among a plurality of frames included in a moving image, a high saturation pixel having a saturation higher than a predetermined threshold; a high saturation pixel rate deriving unit that derives a high saturation pixel rate indicative of a percentage of the high saturation pixels in the one frame; and a scene change judging unit that judges whether or not a scene change is included in the moving image based on different criteria depending on whether or not the high saturation pixel rate in the one frame is higher than a predetermined threshold.

摘要： Provided is an image conversion method that allows for the representation, on a display, the light and shade of a printed image obtained by printing the image on paper. The image conversion method includes a step of acquiring an illumination-light component and a reflectance component from an input image, a step of correcting the illumination-light component in accordance with display luminance information of a print mode in which the input image is to be printed, so that light and shade of the input image displayed on a display come close to light and shade of a printed image obtained by printing the input image in the print mode, and a step of acquiring a combined image by combining the corrected illumination-light component and the reflectance component or the corrected reflectance component.
