Abstract: A three-dimensional information generation unit generates a three-dimensional map (D(X, Y, Z)) (three-dimensional information) regarding a surgical field, based on a surgical field image (K(x, y)) captured by an imaging device. A region-of-interest setting unit (setting unit) then sets at least one region-of-interest in the surgical field image (K(x, y)) captured at a predetermined timing. Based on the three-dimensional map (D(X, Y, Z)) and the position of the region-of-interest set by the region-of-interest setting unit, a region-of-interest estimation unit (estimation unit) estimates an existence position of the region-of-interest from within the surgical field image (K(x, y)) captured at a timing different from the predetermined timing. Subsequently, a zoom processing unit (magnified image generation unit) generates a magnified surgical field image (L(x, y)) in which the estimated region-of-interest is magnified by a predetermined magnification, and a display control unit outputs at least the magnified surgical field image (L(x, y)).

Abstract: An image processing apparatus includes a special light image acquisition unit that acquires a special light image having information in a specific wavelength band, a generation unit that generates depth information at a predetermined position in a living body using the special light image, and a detection unit that detects a predetermined region using the depth information. The image processing apparatus further includes a normal light image acquisition unit that acquires a normal light image having information in a wavelength band of white light. The specific wavelength band is, for example, infrared light. The generation unit calculates a difference in a depth direction between the special light image and the normal light image to generate depth information at the predetermined position. The detection unit detects a position in which the depth information is a predetermined threshold or more as a bleeding point. The present technology is applicable to an endoscope.

Abstract: The present technology relates to an image processing apparatus, an image processing method, and a surgical system, by which a captured image can be displayed with low latency in almost real time. A DMA controller 51 of a CPU 31 divides image data, which is input via an IF card 34, by the number of GPU cards 35-1, 35-2 in a horizontal direction and allocates them. In each of the GPU cards 35-1, 35-2, the image data is subjected to time division processing in the vertical direction. With this, the use of the plurality of GPU cards 35-1, 35-2 increases the speed of processing associated with display for the image data. High-speed display is realized due to reduction in latency. The present technology is applicable to an endoscopic camera, a surgical microscope, and the like.
