Abstract: In a vehicle control system, when an occupant visually recognizes a signboard and signboard course information is included in signboard information corresponding to the signboard, the signboard information is displayed on a display device. When the signboard course information out of the signboard information is visually recognized continuously, a control device generates course information based on the signboard course information. The generated course information is output to a vehicle control ECU, and course change processing based on the course information is performed by the vehicle control ECU.

Abstract: A head-up display device includes: a reflection member disposed in front of a driver who drives a vehicle; a projection unit configured to project light toward the reflection member and display a virtual image in a region superimposed on a superimposing display target when viewed by the driver; and an imaging unit configured to take an image of a region in front of the vehicle to generate a front image that is an image of the region in front of the vehicle. The projection unit adjusts a luminance distribution of a virtual image in accordance with a luminance distribution of a region of the superimposing display target in the front image.

Abstract: A control device in a vehicle display system includes: a gazed image display output unit configured to display a normal gazed image in a part of each of main screen areas; a gazed image visual recognition determination unit configured to determine, based on a line-of-sight state, whether an occupant visually recognizes a normal gazed image in one of the main screen areas; and a main screen area selection unit configured to select, based on an input unit, the main screen area corresponding to the normal gazed image determined to be visually recognized by the occupant. Earlier selection display information displayed in an earlier selection main screen area selected earlier by the main screen area selection unit is displayed in a later selection main screen area selected later.

Abstract: An in-vehicle system includes: a detection unit that detects visual line information of a passerby on the basis of an image obtained by capturing an image in front of a vehicle; a decision unit that decides a motion of the vehicle on the basis of the visual line information of the passerby which is detected by the detection unit; and operation units which perform processing corresponding to the motion of the vehicle which is decided by the decision unit. As a result, the in-vehicle system can attain an effect capable of improving communication between the vehicle and the passerby on the basis of the visual line information of the passerby.

Abstract: An in-vehicle system includes: a first detection unit that detects an illumination state of another vehicle on the basis of an image obtained by capturing a nearby image of a vehicle; a second detection unit that detects a traffic situation of the vehicle; an estimation unit that estimates intention of a signal of the other vehicle on the basis of the illumination state of the other vehicle that is detected by the first detection unit and the traffic situation of the vehicle that is detected by the second detection unit; and operation units that perform processing corresponding to intention of a signal of the other vehicle that is estimated by the estimation unit. As a result, it is possible to attain an effect in which it is not necessary for the in-vehicle system to perform communication with the other vehicles to confirm the signal of the other vehicles.

Abstract: When a pulsed waveform is used to transmit power-supply power in a form of a power packet etc., a filter for reducing harmonic components is disposed on a power transmission side. A switch and a control portion for controlling ON/OFF of a function of the filter are provided to turn ON the function of the filter limitedly at each of timings t1 to t2 and t3 to t4 at which the power is transmitted. The harmonic components are reduced from the waveform of the transmission power by the function of the filter. Radiation noise generated by the wire harness is reduced in a high frequency region. The function of the filter is turned OFF at a timing at which digital information is transmitted so that a waveform of the digital information can be prevented from being deformed.

Abstract: A video display system for a meeting includes a video information terminal device typified by a liquid crystal projector, a video display unit typified by a whiteboard, a server which stores information and a user terminal (mobile terminal) held by a member of the meeting. A host of the meeting transmits information regarding the time of the meeting, members, and contents thereof to the server. A reservation list and a participant list are displayed and updated depending on an attendance/nonattendance answer from a member. A diagram or letters written on the whiteboard during the meeting are captured by the video information terminal device, inverted in brightness, stored in a memory, and displayed as a video image. At the end of the meeting, video data is stored as a file. When the meeting is resumed, the stored file is reproduced, developed in the memory, and displayed as a video image.

Abstract: A projection video display device, which enlarges and projects an image from an image-displaying means, has a housing and a raisable/lowerable mirror and a power supply, a light source, and a lens unit inside the housing. The raisable/lowerable mirror covers a projection-light opening formed in the top surface of the housing and able to rotate with respect to the housing, and has a convex mirror on the inside surface thereof. The raisable/lowerable mirror covering the top surface of the housing forms a smoothly connected, smooth, convexly curved surface with no height difference between the edge of the raisable/lowerable mirror and the front edge of the opening, and a half-bowl-shaped concavity is formed on at least one side of the raisable/lowerable mirror in the direction of the axis of rotation thereof.

Abstract: Without increasing the size of a projection video display device that has a mirror that can be raised and lowered, this invention makes it easy to raise and lower said mirror. In order to do so, this projection video display device, which enlarges and projects an image from an image-displaying means, has a housing (10) and a raisable/lowerable mirror (30) wherein: a power supply, a light source, and a lens unit are accommodated inside the housing (10); said lens unit enlarges light from the light source after said light has been directed to the aforementioned image-displaying means; and the raisable/lowerable mirror (30) covers a projection-light opening (26) formed in the top surface of the housing (10), is provided so as to be able to rotate with respect to the housing (10), and has a convex mirror (110) on the inside surface thereof.
