  • Patent number: 8840252
    Abstract: An image display apparatus improves usability for a user in the case where a screen image is projected on a ceiling as a screen. The image display apparatus includes: a projection unit capable of vertically changing a projection angle; a projection angle detector detecting the projection angle of the projection unit; and a screen image corrector reversing a projected screen image. The screen image corrector switches the projected screen image from a reversed display to a standard display when the projection angle detected by the projection angle detector is less than or equal to a predetermined value.

  • Patent number: 8690350
    Abstract: An image display apparatus detects a projection angle of a projection unit that projects a screen image on a screen and is capable of vertically changing the projection angle, and corrects trapezoidal distortion of the screen image according to the projection angle. The image display apparatus changes the amount and direction of trapezoidal distortion correction based on the projection angle. The image display apparatus also determines whether a projection mode is projection upward to a wall or projection to a ceiling and changes the direction of trapezoidal distortion correction for projection upward to the wall and projection to the ceiling. Specifically, for projection upward to the wall, a correction factor is positive and an upper edge portion of the screen image is compressed for correction; and for projection to the ceiling, a correction factor is negative and a lower edge portion of the screen image is compressed for correction.

  • Publication number: 20120042347
    Abstract: An information processing device, includes a display portion that displays video content that has been received from a server that stores the video content, a storage portion that stores a playback interruption position for the video content, and a video output portion that, in a case where a video acquisition request is received from another device that will restart playback of the video starting from the playback interruption position, acquires the video content from the server, starting from the playback interruption position, and transmits the acquired video content to the other device.
