  • Publication number: 20250095326
    Abstract: A luminance determining unit determines a luminance distribution of an exterior circumstantial image in a line-of-sight direction of a driver, and a luminance changing unit determines a bright region of this luminance distribution. Further, the luminance changing unit determines a luminance after the change in a peripheral region of this bright region. A virtual-image creating unit creates a virtual image based on the determined luminance, and a display processing unit displays this virtual image on a display unit. In this manner, since a display system displays the virtual image for use in increasing the luminance in periphery of the bright region, the feeling of the brightness for the driver can be moderated, and therefore, the visual recognition can be improved. That is, the display system can output the virtual image depending on the circumstances.

  • Patent number: 12252775
    Abstract: There have been cases where transistors formed using oxide semiconductors are inferior in reliability to transistors formed using amorphous silicon. Thus, in the present invention, a semiconductor device including a highly reliable transistor formed using an oxide semiconductor is manufactured. An oxide semiconductor film is deposited by a sputtering method, using a sputtering target including an oxide semiconductor having crystallinity, and in which the direction of the c-axis of a crystal is parallel to a normal vector of the top surface of the oxide semiconductor. The target is formed by mixing raw materials so that its composition ratio can obtain a crystal structure.
