Abstract: A medical system (1) includes a light source (2) that irradiates an imaging target (9) with light, an imaging device (3) that images reflected light from the imaging target (9) irradiated with the light, and a noise reduction processing means (412) that acquires a plurality of images captured by the imaging device (3) and performs noise reduction processing on one image of interest out of a plurality of the images. The noise reduction processing means (412) uses an image N (N is an integer not smaller than 2) frames before the image of interest as a reference image.

Abstract: The present disclosure relates to a video processing system, a medical information processing system, and an operation method capable of obtaining a video with intended image quality. A first medical video captured by a target medical apparatus, which is a first medical apparatus and a second medical video captured by a subject medical apparatus, which is a second medical apparatus are recorded in a video recording unit. Then, a conversion parameter generation unit generates a conversion parameter that brings the image quality of the second medical video close to the image quality of the first medical video by using the first medical video and the second medical video, and an image quality conversion processing unit converts the image quality of a medical video captured by the subject medical apparatus by using the conversion parameter. The present technology can be applied to, for example, a video processing system for a medical institution.

Abstract: A medical system includes a light source configured to irradiate an imaging target with light having different wavelength zones in a first observation mode and a second observation mode, the imaging target being a part of a living body being operated, an imaging apparatus configured to capture reflected light from the imaging target irradiated with the light and output a captured image, a storage controller configured to perform control for causing a storage section to store a first captured image upon the first observation mode as a reference image, a generator configured to compare a second captured image upon the second observation mode with the reference image to generate a parameter used for approximating a color shade of the second captured image to a color shade of the reference image, a color conversion processor configured to perform color conversion processing on the second captured image on a basis of the parameter to output a color-converted image, and a display controller configured to perform control for causing a display section to display the color-converted image.
