A robotic system having movable mechanism of a non-planar inner projection is provided. It comprises a non-planar projection surface, a servo motor, an inner projection element, and a support frame. The servo motor is connected to the non-planar projection surface, and the non-planar projection surface can be rotated synchronously by the servo motor drive. The inner projection element is disposed relative to the non-planar projection surface, the inner projection element generates a target image, and the target image is projected onto the non-planar projection surface to form a display area, and the display area has a fixed boundary. The servo motor and the inner projection element are disposed on the support frame, and when the non-planar projection surface is synchronously rotated by the servo motor, the inner projection element also rotates synchronously.

An electronic apparatus is disclosed. The electronic apparatus includes: a memory storing a first pattern image and a second pattern image, a communication interface comprising communication circuitry configured to communicate with an external terminal apparatus, a projection part including a projection lens, and a processor configured to: control the projection part to project the first pattern image on a screen member comprising a reflector located on a projection surface, and based on receiving a first photographed image which photographed the screen member from the external terminal apparatus through the communication interface, acquire transformation information based on the first photographed image and the first pattern image, control the projection part to project the second pattern image on the projection surface, and based on receiving a second photographed image which photographed the projection surface from the external terminal apparatus through the communication interface, perform color calibration based on the characteristic of the projection surface based on the second photographed image, the second pattern image, and the transformation information.

The present disclosure relates to an information processing apparatus and an information processing method for suppressing a decrease in the accuracy of image projection correction. By use of an image projection model using a distortion factor of an fθ lens with an image height of incident light expressed by the product of a focal point distance f and an incident angle θ of the incident light, the posture of a projection section for projecting an image and the posture of an imaging section for capturing a projection plane to which the image is projected are estimated. The present disclosure may be applied, for example, to information processing apparatuses, projection apparatuses, imaging apparatuses, projection imaging apparatuses, projection imaging control apparatuses, or image projection and imaging systems.

This disclosure describes a head-mounted display with a display assembly configured to display content to most or all of a user's field of view. The display assembly can be configured to display content in far-peripheral regions of the user's field of view differently than content upon which a user can focus. For example, spatial resolution, color resolution, refresh rate and intensity (i.e. brightness) can be adjusted to save resources and/or to bring attention to virtual content positioned within a far-peripheral region. In some embodiments, these changes can save processing resources without detracting from the user's overall experience.

A projection device configured to provide multiple projection modes is provided. The projection device includes a housing module and a projection module. The housing module includes a display screen and multiple protective walls. The display screen includes a display curved surface. The projection module includes an optomechanical assembly and a light guide assembly. In a first projection mode, the optomechanical assembly projects an image light beam to the light guide assembly along a first axis. The light guide assembly projects the image light beam to the display curved surface along a second axis, where the first axis and the second axis are not parallel to each other. In a second projection mode, the light guide assembly is moved out of a transmission path of the image light beam, so that the image light beam is directly projected out of the projection device.

An image projection device includes: a panel unit configured to emit light rays; a projection optical system configured to receive the light rays emitted from the panel unit and to refract the light rays; a reflection unit having a reflection surface for receiving the light rays refracted by the projection optical system and reflecting the light rays; and a screen unit configured to display an image upon receiving the light rays reflected from the reflection surface. The panel unit, the projection optical system, the reflection unit, and the screen unit are arranged such that a distance of a shortest path among paths extending from the panel unit to the reflection unit through the projection optical system along a predetermined linear axis is longer than a distance of a longest path among paths extending from the reflection unit to the screen unit along the predetermined linear axis.

A vehicle display device using a hetero electrochromic film includes: a projector configured to project a predetermined image onto at least one of a windshield and a window of a vehicle; a hetero electrochromic film disposed on at least one of the windshield and the window; and a controller configured to drive the projector and the hetero electrochromic film.

A projection system can include a projector, a screen, a spine, a base, a projector shroud, and a shelf. In some embodiments the spine is made of steel piping. In some embodiments, the spine is hollow and can accommodate a first cable. In some embodiments the screen is an ALR screen. In some embodiments, the system utilizes an ultra-short throw projector lens. In some embodiments, the base is a steel plate. In some embodiments, the projector system includes a counterbalance. In some embodiments, the projector shroud and/or shelf is/are configured to increase ventilation and/or act as heat sink(s). In some embodiments, the projection system includes a remote-control extender.
