  • Patent number: 10816778
    Abstract: An image capture system including two imaging systems of the same structure each having a wide-angle lens, which includes a front group, a reflection surface, and a rear group arranged in order from an object side, has a field angle larger than 180 degrees, and bends an optical axis of the front group toward the rear group by the reflection surface, and an imaging sensor, obtains an image in a solid angle of 4? radian by combining images imaged by the imaging systems. Each of the two wide-angle lenses includes the reflection surface between the front group and the rear group, the reflection surfaces are made to be common to the two imaging systems. This reduces an interval between lenses nearest to the object side in the front groups of the two wide-angle lenses, thereby reducing a distance between maximum field angles of the two wide-angle lenses.

  • Publication number: 20200304724
    Abstract: An imaging apparatus mountable on a moveable apparatus includes a plurality of lighting-imaging units, each configured to capture an image of a different area on an object in a direction intersecting with a movement direction of the moveable apparatus. The each of the plurality of lighting-imaging units includes a light source unit configured to illuminate a partial area on the object as a lighting area; and an image capture unit configured to capture an image of an image capture area set within the lighting area. The plurality of lighting-imaging units captures an image of a non-overlapped lighting area on the object where the lighting areas of the plurality of lighting-imaging units do not overlap with each other.

  • Patent number: 10628696
    Abstract: An imaging device includes a reflection polarization prism having an incident surface on which illumination light emitted from a light emitter is incident and a transmission surface that passes the illumination light entered the incident surface through one surface of a light-transmitting member, an imager including an image sensor having a first light-receiving portion that receives light from a predetermined imaging area transmitting the light-transmitting member and a second light-receiving portion adjacent to the first light-receiving portion that receives the illumination light reflected on an opposite surface to the one surface of the light-transmitting member, and an optical member that emits the light introduced from the predetermined imaging area to the first light-receiving portion and emits the illumination light reflected on the opposite surface of the light-transmitting member to the second light-receiving portion.
