A control section 35 compares angles of view of a main captured image generated by a main imaging section 21 and a subordinate captured image generated by a subordinate imaging section 22. In a case where a result of comparison, by the control section 35, of the angles of view indicates that the angle of view of the main captured image is narrower than the angle of view of the subordinate captured image, an image synthesis section 24 generates a display image by superimposing the main captured image on the subordinate captured image or superimposing the reduced subordinate captured image on the main captured image. In a case where the angle of view of the main captured image is narrower than the angle of view of the subordinate image, the main captured image is set as the display image. It is possible to easily decide a composition during shooting by using the subordinate captured image. It is also possible to confirm an imaging status by using the main captured image.

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.

An imaging device (1) according to the present disclosure includes an imaging unit (2), a signal separating unit (5), a normal line calculating unit (6), and a distance estimation unit (7). The imaging unit (2) includes a plurality of polarization lights (21 to 24) having different polarization directions of light emitted to a subject and a polarization sensor (11) and captures an image of the subject that is simultaneously irradiated with the light from the plurality of polarization lights (21 to 24). The signal separating unit (5) separates pixel signals corresponding to each of the polarization directions from the image captured by the imaging unit (2) and generates an image for every polarization direction. The normal line calculating unit (6) calculates a normal line on a surface of the subject from the image for each of the polarization directions by photometric stereo. The distance estimation unit (7) estimates the shape of the subject on the basis of the normal line calculated by the normal line calculating unit (6).
