The control method of an electronic device includes: acquiring first location information on a projection area of an image projected by the electronic device through a sensor; acquiring second location information on a location where a user is located, through the sensor; and performing at least one of an operation corresponding to a voice input of the user or an operation corresponding to image quality processing based on the first location information and the second location information.

A secure display stand for an electronic device or other object plays electronic media relating to the device on display. A holder holds the electronic device to be displayed, and an arm extends from the surface to the holder. A projector is associated with the arm and directed towards the surface to project media images onto the surface.

Systems integrating display resolution-multiplication solutions can be implemented in a variety of different ways. In many embodiments, the system includes an image projector for projecting image light, an image processor for computing a native image and at least one image shifted in a predefined direction, and at least one switchable grating capable of being switched between diffracting and non-diffracting states. In some embodiments, the switchable grating is optically coupled to the image projector. In a number of embodiments, the switchable gratings have a first configuration for propagating the native image light and at least one other configuration for propagating shifted image light having an angular displacement corresponding to the image shift in a predefined direction. By displaying the native and shifted images sequentially within a human eye integration period, the display resolution can be multiplied.

A projection system and method for depth-based projection of image-based content is provided. The projection system receives a sequence of image frames to be projected on a physical surface of a three-dimensional (3D) structure. The projection system controls a depth sensor to acquire depth data associated with the physical surface and feeds a first input including the acquired depth data and a first image frame of the received sequence of image frames to a neural network-based model. The projection system further receives a set of geometric correction values as a first output of the neural network-based model for the fed first input and modifies the first image frame based on the received set of geometric correction values. The projection system further controls the illumination circuitry to project the modified first image frame onto the physical surface.

Projection systems and/or methods for efficient use of light by recycling a portion of the light energy for future use are disclosed. In one embodiment, a projection display system is disclosed comprising a light source; an integrating rod that receives light from said light source at a proximal end that comprise a reflective surface which may reflecting/recycle light down said integrating rod; of reflecting light down said integrating rod; a relay optical system, said relay optical system further comprising optical elements that are capable of moving the focal plane of the projector display system; and a modulator comprising at least one moveable mirror that reflects light received from the integrating rod in either a projection direction or a light recycling direction.

There is provided an information generation method including, identifying a correspondence relationship between a projector coordinate system and a camera coordinate system, receiving a first operation of designating a first display area representing an arrangement destination of a projection object which is projected on a projection target in a first coordinate system which is one of the camera coordinate system or the projector coordinate system, transforming the first display area into a second display area representing an arrangement destination of the projection object in a second coordinate system which is another of the camera coordinate system or the projector coordinate system based on the correspondence relationship, receiving a second operation of changing at least one of a shape or a position of the second display area, and generating information for changing at least one of a shape or a position of the projection object in accordance with the second operation.

An optical engine module and a projection device are provided. The optical engine module includes a first prism, a light valve, a second prism, and a light-shielding element. The first prism is disposed on a transmission path of an illumination light beam. The light valve is disposed on the transmission path of the illumination light beam from the first prism. The light valve has a reflection surface suitable for converting the illumination light beam into an image beam. The second prism is located between the first prism and the light valve, and is disposed on the transmission path of the illumination light beam from the first prism and on a transmission path of the image beam from the light valve. The light-shielding element is located between the first prism and the second prism.

A display device of an autonomous vehicle is controlled based on data collected from sensors located in or on the vehicle. The display device is used to present one or more images to a driver and/or passengers of the autonomous vehicle. The display device can be, for example, a windshield and/or other window of the vehicle. Image data can be, for example, transformed to improve visual perception by passengers in the vehicle when the images are displayed on a curved shape of the windshield.

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.

A method for automatic keystone correction in a projection system is provided that includes rectifying a first image to be projected using current keystone correction parameters to generate a first rectified image, projecting, by a projector in the projection system, the first rectified image on a projection surface, determining whether or not current keystone correction parameters are providing sufficient keystone correction after the first rectified image is projected, rectifying a second image to be projected using the current keystone correction parameters to generate a second rectified image if the current keystone correction parameters are providing sufficient keystone correction, computing new keystone correction parameters if the current keystone correction parameters are not providing sufficient keystone correction and rectifying the second image to be projected using the new keystone correction parameters to generate the second rectified image, and projecting, by the projector, the second rectified image on the projection surface.
