  • Patent number: 9126533
    Abstract: A driving support device uses a camera mounted on a vehicle for imaging a blind spot area created by a pillar of the vehicle and displays an image taken by the camera on the interior surface of the pillar. A virtual plane passing through boundaries of the blind spot area is set, and an image plane of the camera is set at a predetermined position where a non-displayed area or an excess area, created by deviation between the virtual plane and the image plane of the camera, is reduced. Image data input from the camera is subjected to coordinate transformation on the virtual plane, and an image corresponding to the blind spot area created by the pillar is displayed on the interior surface of the pillar, based on the image data subjected to coordinate transformation on the virtual plane.

  • Patent number: 8094192
    Abstract: A driving support method and a driving support apparatus clearly project an image of a specific target object onto a pillar within a vehicle. The apparatus includes a camera installed on the vehicle that captures a dead-angle area created by the pillar and a projector projecting the image captured by the camera onto the interior surface of the pillar. The driving support unit also includes an image processor that sets a reference point Pc on an indicator on a road surface, sets a virtual plane VP passing through the reference point Pc, performs coordinate conversion for image data input from the camera onto the virtual plane VP, and outputs to a projector the image data for which the coordinate conversion has been performed.

  • Patent number: 8089512
    Abstract: A driving support device, a driving support method, and a computer program provide an image of the peripheral environment of a vehicle which is captured by a camera. The traveling state of the vehicle is obtained and, based on same, a blind spot region for a driver created by a right front pillar, as it would appear after a predetermined period of time, is calculated by taking into consideration the time lag between capture of an image by the camera and projection of that image by a projector. An image corresponding to the calculated blind spot region is extracted from the image captured by the camera, and the extracted image is projected onto the inside surface of the right front pillar.

  • Patent number: 8035575
    Abstract: A driving support method and apparatus for displaying, on a medial side of a pillar of the vehicle, an image of an area which is hidden as a blind spot in a rear-view mirror mounted on or in a vehicle, when looking in the mirror from the driver's position and which is created by the pillar. The apparatus detects a head position of a driver, detects the angle of the rear-view mirror, calculates the area which is hidden as the blind spot on the basis of the detected driver's head position and the detected angle of the rear-view mirror, and projects an image of the area corresponding to the blind spot onto the pillar, the projected image being formed from image data which is obtained from a blind spot camera mounted on the vehicle.

  • Publication number: 20090201173
    Abstract: A CPU obtains road shape information regarding a shape of a road ahead of a vehicle from map information stored in a map information DB. Further, the CPU calculates a blind spot region for a driver generated by a right front pillar. In addition, when it is determined that at least a part of the calculated blind spot region is overlapped with a road ahead in a traveling direction, the CPU displays a shot image corresponding to the blind spot region shot by the camera on a pillar display. Thereafter, when the calculated blind spot region is determined not to be overlapped with the road ahead in the traveling direction within five seconds, the CPU stops the display of a video on the pillar display.

A first constant current source is connected between the emitter of one of the transistors of the third transistor pair and ground. A second constant current source is connected between the emitter of the other transistor of the third transistor pair and ground. A gate circuit is connected to one of the first and second current sources for selectively activating the one connected current source. By selectively activating the current source, the mixer has low power consumption.
