VIDEO DISPLAY DEVICE AND PROJECTOR

A video display device includes performs a first Retinex process on an inputted video and a second Retinex process, which is different from the first Retinex process, on the inputted video. A video composing unit is configured to compose a video processed by the first Retinex processing unit and a video processed by the second Retinex processing unit in accordance with a feature of the inputted video, which is then displayed. In a process of composing the video processed by the first and second Retinex processing units, the video composing unit is configured to perform a process of converting a luminance level for each pixel so that more output luminance levels are assigned to a luminance band having a large frequency distribution to improve visibility of the video. A gain of the luminance level converting process is varied in accordance with an average pixel value level of the inputted video.

The appearance of content that guides a traveling path of a vehicle is improved. When a display control ECU shifts a path line, which is expressed by path line information included in map information for navigation, in a vehicle transverse direction in accordance with a distance along the vehicle transverse direction between a position of a vehicle and the path line, the display control ECU causes content to be displayed on a HUD at a corresponding position on the shifted path line.

Pixel intensity modulation using modifying gain values

A visual perception device has a look-up table stored in a laser driver chip. The look-up table includes relational gain data to compensate for brighter areas of a laser pattern wherein pixels are located more closely than areas where the pixels are further apart and to compensate for differences in intensity of individual pixels when the intensities of pixels are altered due to design characteristics of an eye piece.

In a head mounted display 100, a memory 71 stores an application. An image pickup unit 74 takes an image of a site of a user 1, and a position specifying unit 73 specifies a position and a direction of the head mounted display 100. A detector 75 detects a position indicated by the user 1 on the basis of the image taken by the image pickup unit 74, and a setting unit 76 sets a position indicating a home position on the basis of a result detected by the detector 75 and the position and the direction specified by the position specifying unit 73.

Realistic virtual/augmented/mixed reality viewing and interactions

The present invention discloses systems and methods for both viewing and interacting with a virtual reality (VR), an augmented reality (AR) or a mixed reality (MR). More specifically, the systems and methods allow the user to interact with aspects of such realities including virtual items presented in such realities or within such environments by manipulating a control device that has an inside-out camera mounted on-board. The apparatus or system uses two distinct representations including a reduced representation in determining the pose of the control device and uses these representations to compute an interactive pose portion of the control device to be used for interacting with the virtual item. The reduced representation is consonant with a constrained motion of the control device.

This application provides a projection connection control method and an electronic device. The method includes: A transmit end device obtains preemption capability information from a receive end device, where the preemption capability information indicates whether the receive end device supports projection connection preemption; and when the receive end device supports projection connection preemption, the transmit end device sends first configuration information to the receive end device in response to a user instruction, so as to configure the receive end device to not support projection connection preemption.

AR HEADSET WITH AN IMPROVED DISPLA

Augmented reality headsets. A plurality of tilted pin-mirrors imbedded between an inner surface and an outer surface of a combiner, where the plurality of tilted pin-mirrors are configured to reflect the guided image light towards the eye box, and wherein the plurality of pin-mirrors include one or more gaps between them wherein the one or more gaps allow the passage of an ambient light through the combiner towards the eye box.

DISPLAY METHOD FOR DISPLAY SYSTEM, DISPLAY METHOD FOR DISPLAY APPARATUS, AND DISPLAY SYSTEM

A display method includes, determining a first target value by correcting a first luminance value representing luminance at a first position in a first image based on a second luminance value representing luminance at a second position in the first image, displaying, by the display apparatus, on the display surface a first corrected image generated by correcting the first image in such a way that a luminance at the first position in the first image becomes the first target value, displaying, by the display apparatus, on the display surface a third corrected image generated by using a changed first target value obtained by changing the first target value based on a second target value based on a fourth luminance value representing luminance at a fourth position in the second image, when the second target value is smaller than the first target value.

In the case in which a loss of the viewpoint position of a driver occurs when a viewpoint position follow-up warping control is executed to update warping parameters according to the viewpoint position of the driver, and then the viewpoint position is re-detected, it is suppressed that the appearance of an image instantaneously changes in accordance with the update of the warping parameters and the driver is caused to feel uneasy. When the viewpoint loss in which at least one position of the right and left viewpoints becomes unclear is detected, a control unit, which executes the viewpoint position follow-up warping control, maintains, in a viewpoint loss period, the warping parameters set immediately before the viewpoint loss period, and, when the viewpoint position is re-detected after the viewpoint loss period, invalidates at least one warping process using the warping parameters corresponding to the re-detected viewpoint position.
