Abstract: A vehicle-mounted stereo camera device that achieves high-precision distance detection is provided. The provided vehicle-mounted stereo camera device includes a left camera and right camera disposed on a vehicle via a holder to cause visual fields to overlap each other, a stereo processor that calculates a distance to a body outside the vehicle based on images captured by the left camera and right camera and on positions on the vehicle, first and second geomagnetic sensors respectively disposed near the left camera and right camera, and a third geomagnetic sensor disposed on the holder. The stereo processor compares a geomagnetic value detected by the first or second geomagnetic sensor with a geomagnetic value detected by the third geomagnetic sensor, detects a displacement amount of the left camera or right camera, and changes a cutout position in the image captured by the left camera or right camera based on the displacement amount.

Abstract: The projection display apparatus includes a light source unit, a light deflector, a first light receiver, a second light receiver, and a calculator. The light deflector deflects at least part of incident light coming from the light source unit to a first optical path so as to produce a projection light, and deflects a remaining part of the incident light to a second optical path. The first light receiver receives the at least part of the incident light that has been reflected by the projection surface. The second light receiver receives the remaining part of the incident light. The calculator calculates a distance from the projection display apparatus to a projection surface based on light reception results obtained by the first light receiver receiving the at least part of the incident light and the second light receiver receiving the remaining part of the incident light.

Abstract: A night vision imaging apparatus includes a light projecting section, a light amount controller, an imaging section, and a recording section. The light projecting section casts a near infrared ray as illumination light on an illumination area. The light amount controller controls an amount of the illumination light on each one of sub-areas forming the illumination area. The imaging section images the illumination area, and generates image data. The recording section records the image data generated by the imaging section. The light amount controller divides an image shown in the image data into a plurality of divided portions, and determines a light intensity of each one of the plurality of divided portion, and then controls an amount of the illumination light to be casted on a sub-area corresponding to each one of the plurality of divided portions among the sub-areas of the illumination area based on the determined light intensity.

Abstract: A vehicle-mounted stereo camera device that achieves high-precision distance detection is provided, including a left camera and a right camera disposed to cause visual fields to overlap each other, a first enclosure and a second enclosure that enclose the left camera and the right camera and have portions within the visual fields of the left camera and the right camera, respectively, and a stereo processor that calculates a distance to a body outside the vehicle based on images captured by the left camera and the right camera and on positions of the left camera and the right camera on the vehicle. The stereo processor detects displacement amounts of the left camera and the right camera based on amounts of change in positions of the first enclosure and the second enclosure within the visual fields of the left camera and the right camera, and changes a cutout position in the images captured by the left camera and the right camera.
