Abstract

To provide a hardly visible imaging device.
An imaging device, which comprises an imaging unit installed inside a window glass of a building, capturing images of outside of the window glass through the window glass, and
a fixing part fixing the imaging unit toward the window glass.

First claim

What is claimed is:

1 . An imaging device, comprising: an imaging unit installed inside a window glass of a building, to capture images of outside of the window glass through the window glass; and
a fixing part to fix the imaging unit toward the window glass, wherein the fixing part has a transparent plate to which the imaging unit is attached, and a transparent attaching part to attach the transparent plate to an inside surface of the window glass.

2 . The imaging device according to claim 1 , wherein the attaching part is an attaching part which attaches the transparent plate with an inclination to the inside surface of the window glass, so that the distance between the lower edge of the transparent plate and the inside surface of the window glass is wider than the distance between the upper edge of the transparent plate and the inside surface of the window glass, or the distance between the lower edge of the transparent plate and the inside surface of the window glass is narrower than the distance between the upper edge of the transparent plate and the inside surface of the window glass.

3 . The imaging device according to claim 1 , which further has a wiring connected to the imaging unit, formed on the transparent plate, and
wherein the wiring has light transparency.

4 . The imaging device according to claim 3 , wherein the wiring is constituted by a metal mesh.

5 . The imaging device according to claim 1 , wherein the transparent plate has a holding part which holds at least a part of the imaging unit, and the holding part is a through-hole that pierces the transparent plate in the thickness direction, or a hole that recesses from the surface of the transparent plate to the thickness direction.

6 . The imaging device according to claim 5 , wherein the through-hole or hole as the holding part is formed with an inclination to the surface of the transparent plate.

7 . The imaging device according to claim 1 , wherein the transparent plate has eaves extending toward the window glass side than a lens of the imaging unit.

8 . The imaging device according to claim 1 , which further has a mesh to cover a lens of the imaging unit, provided on the window glass side surface of the transparent plate.

9 . The imaging device according to claim 8 , wherein the reflectance of the mesh, on the lens side surface, is lower than the reflectance on the window glass side surface.

10 . The imaging device according to claim 1 , which further has a low refractive index layer having a refractive index lower than the refractive index of the window glass, provided between the transparent plate and the window glass.

11 . The imaging device according to claim 10 , wherein the low refractive index layer is a variable refractive index layer having a variable refractive index.

12 . An imaging device, comprising:
an imaging unit installed inside a window glass of a building, to capture images of outside of the window glass through the window glass; a fixing part to fix the imaging unit toward the window glass, wherein the fixing part has a transparent plate to which the imaging unit is attached, and an attaching part to attach the transparent plate to an inside surface of the window glass; and an antenna having light transparency, formed on the transparent plate.

13 . The imaging device according to claim 12 , wherein the antenna is constituted by a metal mesh.

14 . An imaging device, comprising:
an imaging unit installed inside a window glass of a building, to capture images of outside of the window glass through the window glass; a fixing part to fix the imaging unit toward the window glass; and a partial reflective layer which partially reflects light entering from outside the window glass toward the imaging unit, provide on the inside surface of the window glass.

15 . The imaging device according to claim 14 , wherein the partial reflective layer is provided in a portion included in the field of view of the imaging unit, on the window glass.
