  • Publication number: 20180164951
    Abstract: In a projection-type video display device that displays an image by projecting the image onto a projection object starting from a desk surface, a display screen on which a position and a gesture operation of a user are reflected is displayed in a predetermined area. An illumination and a camera are disposed in the projection-type video display device installed on the desk surface, a gesture using user's fingers is detected, and, for example, a menu screen and an operation guide are displayed according to the gesture. The shadows of the fingers are photographed by the camera, and a gesture is detected. According to the gesture, the display screen is moved, rotated, divided, or enlarged/reduced, or a menu screen is displayed. The display direction is determined in consideration of the direction of sides of the desk.

  • Patent number: 9992469
    Abstract: An imaging processing device and an imaging processing method that can solve a problem generated in visible light photographing in a case where DBPF is used instead of an infrared cut filter. An imaging sensor includes a color filter, and DBPH that has a transmission characteristic in a visible-light band, blocking characteristic in a first wavelength band adjacent to a long-wavelength side of the visible-light band, and transmission characteristic in a second wavelength band that is a part of the first wavelength band. A signal processing unit subtracts an infrared signal, which is output from an infrared pixel, from each color signal output from a pixel in each color of visible light in the imaging sensor. Here, in a case where each color signal reaches a pixel saturation level, control of performing correction in such a manner that an infrared signal subtracted from each color signal is lowered is performed.

  • Patent number: 9942596
    Abstract: The present invention is intended to permit both real-time display of a picture represented by a non-compressed video signal on a television and display of a picture represented by a compressed video signal at any desired time by simultaneously transmitting the compressed video signal and non-compressed video signal via one interface. An STB packetizes a compressed video signal, and multiplexes the compressed video signal and a blanking signal combined with a non-compressed video signal. Thus, both the video signals are transmitted simultaneously. A picture represented by the non-compressed video signal is displayed on a television in real time. The compressed video signal is stored in a storage medium incorporated in the television, read at any user's desired time, and decoded so that a picture represented by the compressed video signal can be viewed at the user's desired time.
