It is an object to provide a technique capable of suppressing a reduction in a visual quality. A display device includes a display panel and a parallax harrier panel in which a plurality of openings capable of being switched into a light transmitting state and a light shielding state with respect to light of the display panel are arrayed. A display control method performs a control of bringing a predetermined number of openings adjacent to each other into a first state which is one state of the light transmitting state and the light shielding state to form a plurality of first state parts and bringing remaining openings out of the plurality of openings into a second state which is another state of the light transmitting state and the light shielding state, and a control of moving the first state parts at a pitch corresponding to two or more openings.

A blended optical device includes a first objective with a first axis and a first image position adjustment means for adjusting the position of a first image. An electronic control circuitry is configured to control the first adjustment means to adjust a position of the first image. A second objective includes a second axis and a variable focus mechanism, and a blender configured to form a blended image from the first image and a second image. The electronic control circuitry is configured to receive data from the second objective regarding a range to a target of the second objective as a function of the focus setting, and to adjust the position of the first image so that the blended image is corrected for parallax errors.

A stereoscopic endoscope that includes at least one image sensor, one or more processing devices, and a display device. The image sensors sense a pair of stereo images, based on capturing light passing through apertures electronically defined at a first aperture location and a second aperture location, respectively, on a liquid crystal layer within the endoscope. The size of each aperture, spacing between the apertures, and polarization state associated with each aperture are controlled using corresponding control signals provided to the liquid crystal layer. The image data captured through the apertures is used to generate control signals representing one or more views of a surgical scene. The views are then presented on a display device.

An image capturing apparatus includes an image sensing device, a first acquisition unit, a second acquisition unit, and a display control unit. The first acquisition unit acquires an image acquired by using the image sensing device and three-dimensional information regarding a subject in the image. The three-dimensional information includes depth information regarding the image. The second acquisition unit acquires a shaping resolution indicating a resolution used by a shaping device to shape an object in a three-dimensional shape of the subject. The display control unit displays, based on the shaping resolution and the three-dimensional information regarding the subject, a relationship between a size of the subject and magnitude of the shaping resolution.
