  • Patent number: 11648878
    Abstract: A luminance determining unit 14 determines a luminance distribution of an exterior circumstantial image in a line-of-sight direction of a driver 300, and a luminance changing unit 15 determines a bright region 301 of this luminance distribution. Further, the luminance changing unit 15 determines a luminance after the change in a peripheral region 302 of this bright region 301. A virtual-image creating unit 16A creates a virtual image based on the determined luminance, and a display processing unit 17 displays this virtual image on a display unit 200. In this manner, since a display system 1A displays the virtual image for use in increasing the luminance in periphery of the bright region 301, the feeling of the brightness for the driver 300 can be moderated, and therefore, the visual recognition can be improved. That is, the display system 1A can output the virtual image depending on the circumstances.

  • Patent number: 11647370
    Abstract: When storing captured image data in an information server, a mobile information terminal transmits related information (date and time information, location information, direction angle information, information of a distance to a subject, and user identification information) at the time of imaging to the information server. In addition, when making a request for the image data stored in the information server, current terminal information and image search conditions describing image data replay conditions are transmitted to the information server. The information server searches for corresponding image data based on the current terminal information and the image search conditions and transmits the corresponding image data to the mobile information terminal. The mobile information terminal displays the received image data on the display unit as a related image. Therefore, a user can effectively recall the memories, such as a situation or impression at the time of imaging.

  • Patent number: 11641390
    Abstract: When download operations get started in unison in conformity to RSS metafile delivery time-and-date information, the traffic is temporarily concentrated to a server, resulting in the risk of a system failure or else. In addition, it is inevitable to periodically check whether an RSS file on Web server is updated or not; so, users must delete update-unnecessary RSS files from those objects to be monitored. In view of this, the periodical update check timing of download control information is dispersed, thereby scattering download requests to the server. The download control information is provided with the information indicating whether such download control information is put under update management and/or expire time-and-date information in case the update management is to be done, whereby an information processing apparatus performs, based on the information, erase processing of the download control information when the download processing is completed.
