  • Publication number: 20220296087
    Abstract: An endoscope system, a control device, and a control method are capable of performing more satisfactory observation. A cutout processing unit cuts out a part of an entire image obtained by imaging an entire field of view range of a rigid endoscope in accordance with a cutout region set around a position deviated from a center point of the entire image and generates an oblique image viewed in an oblique direction with respect to an optical axis of the rigid endoscope. An acquisition unit acquires an instruction command to move the oblique image in a predetermined rotation direction, and a region setting unit moves the cutout region around the center point of the entire image in a direction according to the instruction command along an inner periphery of a circle in which the cutout region is inscribed. The present technology is applicable to, for example, an endoscope system.

  • Publication number: 20220277522
    Abstract: The present technology is a surgical image display system, an image processing device, and an image processing method that enable to assist grasping of a distance in a depth direction in a space in which a stereoscopic image is reproduced when a three-dimensional image is stereoscopically viewed. An image of an observation region is shot from two different viewpoints, and a three-dimensional image that reproduces a stereoscopic image of the observation region is acquired. There is generated an output image that outputs the acquired three-dimensional image and depth distortion information that represents magnitude of distortion in a depth direction in a stereoscopic image space in which a stereoscopic image of the observation region is reproduced by stereoscopically viewing the three-dimensional image. The present technology can be applied to an operative field camera system for medical facilities that shoots an image of a field of view (operative field) of a surgical site.
