Abstract
The in-vehicle imaging system includes a first camera and a second camera that are disposed to capture an image through a window glass of a vehicle, and an electric heating wire provided on a glass plate of the window glass. A focal length of the first camera is shorter than a focal length of the second camera. The first camera and the second camera are disposed such that a second angle of view region, which is a region of a glass plate that overlaps with the angle of view range of the second camera, is not positioned below a first angle of view region, which is a region of a glass plate that overlaps with the angle of view range of the first camera, and the first angle of view region and the second angle of view region have an overlapping portion.
Claims5
An in-vehicle imaging system comprising:
- a first camera and a second camera that are disposed to capture an image through a window glass of a vehicle;
- and
- an electric heating wire provided on a glass plate of the window glass, wherein:
- a focal length of the first camera is shorter than a focal length of the second camera;
- the first camera and the second camera are disposed such that a second angle of view region that is a region of the glass plate overlapping with an angle of view range of the second camera is not positioned below a first angle of view region that is a region of the glass plate overlapping with an angle of view range of the first camera, and such that the first angle of view region and the second angle of view region have an overlapping portion;
- and
- the electric heating wire is disposed around the overlapping portion excluding the second angle of view region and a region of the glass plate positioned below the first angle of view region.
A vehicle window glass that is attached to a vehicle equipped with a first camera and a second camera having a focal length longer than a focal length of the first camera, the vehicle window glass comprising:
- a glass plate;
- and
- an electric heating wire that is disposed on the glass plate, wherein:
- the first camera and the second camera are provided in the vehicle to capture an image through the glass plate;
- the glass plate has a second angle of view region that is a region of the glass plate overlapping with an angle of view range of the second camera and a first angle of view region that is a region of the glass plate overlapping with an angle of view range of the first camera;
- the second angle of view region is not positioned below the first angle of view region, and the first angle of view region and the second angle of view region have an overlapping portion;
- and
- the electric heating wire is disposed around the overlapping portion excluding the second angle of view region and a region of the glass plate positioned below the first angle of view region.
