|1. (WO2018221041) MEDICAL OBSERVATION SYSTEM AND MEDICAL OBSERVATION DEVICE|
|Title:||MEDICAL OBSERVATION SYSTEM AND MEDICAL OBSERVATION DEVICE|
[Problem] To enable the acquisition of high-quality images using a more suitable mode. [Solution] A medical observation system comprises a medical observation device and an image processing device. The medical observation device has a plurality of imaging elements and a branching optical system that separates incident light into a plurality of beams of light, the plurality of beams of light separated by the branching optical system are guided to at least one of the imaging elements, images having mutually different brightness are imaged by two or more of the plurality of imaging elements, and the 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 a first synthesized image or a second synthesized image, said first synthesized image being based on a plurality of images having mutually different brightness and having a wider dynamic range than each of the plurality of images, said second synthesized image being based on a plurality of images imaged by the two or more imaging elements having mutually different optical distances from the branching optical system, and having a greater depth of field than each of the plurality of images.
