摘要： According to an aspect of the present invention, provided is an image processing device comprising a saturation value acquisition unit configured to acquire a saturation value of a target pixel or a saturation value of a target small area including a target pixel and peripheral pixels around the target pixel, and a correction unit configured to correct the target pixel so that a corrected gradation characteristic obtained by correcting the target pixel matches a gradation characteristic synthesized by mixing a color gradation characteristic and a monochrome gradation characteristic at a predetermined mixing ratio based on the saturation value, wherein assuming that the saturation value is c, and the mixing ratio of the color gradation characteristic is W, a value of W is represented by variable c as a relationship W=f(c) and satisfies a following condition. Condition: There is a saturation value c and a multiplier a which satisfy f(c)>αg(c), and α≥1, wherein a relationship in which the mixing ratio W increases in proportion to the saturation value c is W=g(c) and the saturation value is equal to or greater than a threshold value.

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.
