Optimizations are provided for late stage reprojection processing for a multi-layered scene. A multi-layered scene is generated. Late stage reprojection processing is applied to a first layer and different late stage reprojection processing is applied to a second layer. The late stage reprojection processing that is applied to the second layer includes one or more transformations that are applied to the second layer. After the late stage reprojection processing on the various layers is complete, a unified layer is created by compositing the layers together. Then, the render the unified layer is rendered.

This disclosure describes a system configured to present primary and secondary, tertiary, etc., virtual reality content to a user. Primary virtual reality content may be displayed to a user, and, responsive to the user turning his view away from the primary virtual reality content, a sensory cue is provided to the user that indicates to the user that his view is no longer directed toward the primary virtual reality content, and secondary, tertiary, etc., virtual reality content may be displayed to the user. Primary virtual reality content may resume when the user returns his view to the primary virtual reality content. Primary virtual reality content may be adjusted based on a user's interaction with the secondary, tertiary, etc., virtual reality content. Secondary, tertiary, etc., virtual reality content may be adjusted based on a user's progression through the primary virtual reality content, or interaction with the primary virtual reality content.

In the present specification, an image processing device and an image processing method for same are disclosed. An image processing device for processing images according to an embodiment of the present invention comprises: a receiving unit for receiving content; a controller for turning retinal scanning on and measuring an accommodation, and calculating a focal depth based on the measured accommodation and controlling in order to generate an image according to the calculated focal depth; and an output unit for outputting the generated image.

A head-up display device includes: a cover having a light-transmissive light exit part; a first case mating with the cover and having a light entry part for entry of display light and a housing part housing a reflecting member; a light source unit outside the housing part; and a second case covering the light source unit and fastened to the first case. The device has a heat radiator of higher rigidity than the second case, having a wall part that externally projects from the housing part through the intervening light entry part, the light source unit affixed to the wall part to diffuse the heat from the light source unit; and includes a mating part in which the second case and the wall part mate together, the second case fastened to the heat radiator at locations to either side of the mating part.

A display system comprises a projector combined with a retro reflective screen and a viewer distance from the projector such that the observation angle is less than approximately 2-3 degrees. The brightness of the image on the screen for the proposed display system is increased by a factor of 100-500 as compared to traditional display systems with for an equivalent power/intensity light source.

This disclosure describes a system configured to present primary and secondary, tertiary, etc., virtual reality content to a user. Primary virtual reality content may be displayed to a user, and, responsive to the user turning his view away from the primary virtual reality content, a sensory cue is provided to the user that indicates to the user that his view is no longer directed toward the primary virtual reality content, and secondary, tertiary, etc., virtual reality content may be displayed to the user. Primary virtual reality content may resume when the user returns his view to the primary virtual reality content. Primary virtual reality content may be adjusted based on a user's interaction with the secondary, tertiary, etc., virtual reality content. Secondary, tertiary, etc., virtual reality content may be adjusted based on a user's progression through the primary virtual reality content, or interaction with the primary virtual reality content.

A display apparatus includes a frame, an image display apparatus attached to the frame, and a distortion correction apparatus. The image display apparatus includes an image forming apparatus and an optical system configured to guide an image from the image forming apparatus to a pupil of an observer. When it is assumed that a direction, which corresponds to a first direction of the image, of the image forming apparatus is an X-direction and a direction, which corresponds to a second direction of the image which direction is different from the first direction, of the image forming apparatus is a Y-direction, the image forming apparatus is curved in the X-direction and/or in the Y-direction. The distortion correction apparatus corrects an input image signal to correct a distortion of an image to be observed.

To provide a head-mounted display excellent in portability and operability. A head-mounted display according to the present technology includes a main body and an input operation section. The main body includes a display section configured to present an image to a user and is configured to be mountable on a head of the user. The input operation section includes a first detection element that extends in a first axis direction and is provided in the main body and electrostatically detects an operation position in the first axis direction, and a first guide section that guides an input operation of the user along the first axis direction on the first detection element, and controls the image.
