Abstract:
The purpose of the present invention is to provide an image processing device, an image processing method, and an image processing program capable of performing image processing useful for generating an image that is highly visible and that does not look unnatural to a user such as a doctor. Provided is an image processing device equipped with a weighting determination unit and a luminance calculation unit, wherein: a region that constitutes at least a portion of an input image input to the image processing device, and that comprises a plurality of pixels, is defined as a watched region; the input image is an image represented in an RGB color space, either originally or as a result of being subjected to a calculation after being input to the image processing device, that is, each pixel comprises an R component constituting a red color, a G component constituting a green color, and a B component constituting a blue color; when these R, G, and B components are collectively defined as an RGB component, the weighting determination unit determines a weighting coefficient for each RGB component in the watched region on the basis of the magnitude of the RGB component relative to the magnitudes of the other RGB components in the watched region; and the luminance calculation unit calculates a luminance for each pixel included in the watched region, on the basis of each weighting coefficient.
