  • Publication number: 20250148980
    Abstract: Display devices and driving methods are disclosed. In one example, a display device includes pixel groups each including pixels arranged in a first direction are arranged in a second direction intersecting the first direction. A first transistor is provided in each pixel and controls light emission luminance of a light emission element. A first capacitor provided in each pixel is connected between a gate and a source of the first transistor. A display control unit performs first correction processing that simultaneously corrects threshold voltages of the first transistors in the pixel groups, restores a source-gate voltage of the first transistor before the start of the first correction processing, performs second correction processing of sequentially correcting the threshold voltage of the first transistor for each of the pixel groups, and supplies a pixel signal voltage to a gate of the first transistor after the second correction processing.

  • Patent number: 12294691
    Abstract: An image display apparatus according to an embodiment of the present technology includes a plurality of projection units, a screen, and an image generation unit. The plurality of projection units projects image light corresponding to image data with reference to projection axes thereof and is disposed such that the projection axes face in directions different from each other along a first plane. The screen is disposed to intersect with the first plane at a first elevation angle (?i) and diffuses and outputs the image light projected along the first plane at a second elevation angle (?o) different from the first elevation angle (?i). The image generation unit generates the image data for displaying a plurality of viewpoint images corresponding to viewpoints at which the screen is observed at the second elevation angle (?o) on the basis of the directions of the projection axes on the first plane.

    Abstract: An information processing apparatus (10) includes a display generation unit (53), an eye-attracting area detection unit (51), a map generation unit (52), an image correction unit (54), and a display control unit (55). The display generation unit (53) generates a plurality of viewpoint images to be displayed as a stereoscopic image. The eye-attracting area detection unit (51) detects an eye-attracting area of a virtual space to which visual attention of a user needs to attracted. The map generation unit (52) generates a control map indicating a distribution of the degree of eye-attractiveness in a viewpoint image per viewpoint image based on the distance from the eye-attracting area. The image correction unit (54) adjusts the degree of eye-attractiveness of the viewpoint image based on the control map. The display control unit (55) displays the stereoscopic image in the virtual space using the plurality of viewpoint images whose degrees of attractiveness have been adjusted.

  • Publication number: 20240017669
    Abstract: A display image is obtained by superimposing an image showing a vehicle on a captured image obtained by capturing an image on a rear side from the vehicle. For example, the image showing the vehicle is a computer graphics image. For example, a change is made in a superimposed positional relationship between the captured image and the image showing the vehicle in accordance with motion of a viewpoint of a driver. Since the display image is not only made from the captured image obtained by capturing an image on a rear side from the vehicle, but the display image is obtained by superimposing the image showing the vehicle on the captured image, it is possible to easily provide a sense of distance by motion parallax.
