Abstract: [Problem] To allow a plurality of doctors spatially isolated from each other to cooperate in a more preferable aspect.
[Solution] A medical observation system includes: a first medical signal processing device including a first signal processing unit configured to acquire first image data corresponding to a result of image capturing of an affected part by a medical observation device and provide first signal processing to the first image data; and a second medical signal processing device including a second signal processing unit configured to acquire second image data corresponding to the result of image capturing from the first medical signal processing device through a predetermined network and provide second signal processing to the second image data. The second signal processing unit transmits information related to the second signal processing to the first medical signal processing device. The first signal processing unit controls the first signal processing in accordance with the second signal processing.

Abstract: Provided is a medical observation system including a medical observation device and an image processing device. The medical observation device includes a plurality of imaging elements and a branching optical system configured to split incident light into a plurality of rays of light, and each of the plurality of rays of light split by the branching optical system is guided to at least one of the plurality of imaging elements. Of the plurality of imaging elements, two or more imaging elements each capture images having mutually different brightness, and two or more imaging elements are arranged so as to have mutually different optical distances from the branching optical system. The image processing device generates at least one of a first composite image based on a plurality of images having mutually different brightness, the first composite image having a wider dynamic range than each of the plurality of images, or a second composite image based on a plurality of images captured by each of the two or more imaging elements having different optical distances from the branching optical system, the second composite image having a deeper depth of field than each of the plurality of images.
