Abstract
The present disclosure relates to an image processing device, and an image processing method that enable display of an endoscopic image in an easy-to-view manner, and a medical imaging system. The image imaged by an endoscope device is smoothed by LPF and lightness I, chromaticity r, g, and brightness Y are obtained from a smoothed image. A histogram is obtained in units of blocks using the brightness Y, and a frequency in a direction being an upper order is obtained as a gradient bias feature amount Bb. Furthermore, the lightness and the chromaticity are also obtained as feature amounts Ib, rb and gb of lightness and chromaticity in units of blocks. Then, on the basis of a four-dimensional feature amount including Ib, rb and gb, Bb, a region of a subject in an image is classified into a surgical tool, gauze, or the like by a classifier, a region not classified into any of them is recognized as a biological tissue, and AE, AF, and blur correction are performed only with information of the region recognized as the biological tissue. The present disclosure can be applied to an endoscope system, a microscope system, and the like.
