To make it possible to more adequately perform switching between a filmed image of a camerawork operated by a user and a filmed image of a camerawork operated by a subject other than the user. There is provided an information processor including: an acquisition unit that acquires information regarding a motion of a user; and a control unit that controls, on a basis of the information regarding the motion of the user, switching between a first display region corresponding to a first camerawork operated by the user and a second display region corresponding to a second camerawork operated by a subject other than the user.

An information processing apparatus includes a processor and a memory connected to or incorporated in the processor. The processor acquires viewpoint information regarding at least one virtual viewpoint, and presents quality information indicating a quality of a virtual viewpoint video that is creatable with the viewpoint information as a reference, on the basis of a plurality of motion picture data obtained by being captured by a plurality of imaging devices.

Elevator maintenance space projection systems and elevator systems including a projector located within an elevator shaft and arranged to project a display space within the elevator shaft such that the display space includes one or more projected images identifying at least one of a safety volume, a refuge space, and a maintenance location.

The present technology relates to a reproduction device, a reproduction method, and a recording medium capable of suppressing influence of motion parallax and image distortion. There is provided a reproduction device including an image processing unit that performs processing including: projecting an image captured from a specific position in a real space on a projection surface arranged according to a reference position set in a virtual space; acquiring a head movement amount of a user viewing the projected image; changing, according to the head movement amount with respect to the reference position in a first direction that is at least one of a left-right direction or an up-down direction as viewed from the user, a first relative distance between the reference position and a user position in the first direction; changing, according to the head movement amount with respect to the reference position in a second direction that is a front-back direction as viewed from the user, a second relative distance between the reference position and the user position in the second direction; and causing a change amount of the first relative distance to be smaller than a change amount of the second relative distance. The present technology can be applied to, for example, a head mounted display.

An information processing device which controls one projector and another projector includes: a display unit which displays a first operation screen for managing the one projector and a second operation screen for managing the another projector; an input unit which accepts an operation on the first operation screen and the second operation screen; and a control unit which controls the one projector and the another projector, based on the operation accepted by the input unit. When the information processing device is switched from a first state where the first operation screen is operable to a second state where the second operation screen is operable, the control unit causes the second operation screen where an item corresponding to a predetermined item selected on the first operation screen in the first state is selected, to be displayed in the second state.

A display device (1) includes a light-emitting device (10), a reflective liquid crystal element (20), and an optical member (30). The light-emitting device (10) includes a plurality of light-emitting units (142) and a light-transmitting unit (144) located between the light-emitting units (142) adjacent to each other. The light-emitting device (10) is located between the reflective liquid crystal element (20) and the optical member (30). The plurality of light-emitting units (142) emit light toward the reflective liquid crystal element (20). The light emitted from the plurality of light-emitting units (142) is reflected by the reflective liquid crystal element (20), transmitted through the light-emitting unit (142) of the light-emitting device (10), and formed into an image by the optical member (30).

There is provided a transmission system, a transmission method, and a transmission device that make it possible to inhibit deterioration in quality of transmission signals while reducing the number of times of compensation on transmission signals in a case where a plurality of devices is connected in a daisy chain. The transmission system includes a plurality of sub devices and a main device that are connected in a daisy chain. The main device includes a main connector connected to the first sub device of the plurality of sub devices, the main connector being configured to output transmission signals of a plurality of channels. The plurality of sub devices each includes a first sub connector connected to a preceding device, the first sub connector being configured to receive the transmission signals, a compensation unit disposed to correspond to a channel obtained as a result of thinning out, at predetermined intervals, channels other than a channel of an own device signal used by the sub device to which the compensation unit belongs, the compensation unit being configured to perform compensation on the transmission signals, and a second sub connector configured to shift channels of the transmission signals received from the preceding device other than the own device signal by the number of channels of the own device signal and output the transmission signals. The present technology is applicable to, for example, a multi-monitor system.

There is provided systems and methods for performing actions based on light signatures. An exemplary system includes a light source, a light detector, a non-transitory memory storing a plurality of light signatures and a hardware processor. The hardware processor executes an executable code to illuminate, using the light source, a target object with a first light, collect, using the light detector, a second light being a reflection of the first light by the target object, match the second light with one of the plurality of light signatures, and perform an action in response to matching the second light with the one of the plurality of light signatures.
