Abstract
Embodiments provide image capturing apparatuses having a screen, a plurality of mirrors and a plurality of cameras. The plurality of mirrors and the plurality of cameras is arranged such that the plurality of cameras capture a portion of the screen via a respective one of the plurality of mirrors, wherein the plurality of cameras is arranged obliquely with respect to the screen.
Claims24
An image capturing apparatus, comprising:
- a screen;
- a plurality of mirrors;
- and
- a plurality of cameras;
- wherein the plurality of mirrors and the plurality of cameras are arranged such that the plurality of cameras each capture a portion of the screen via a respective one of the plurality of mirrors;
- and
- wherein the plurality of cameras is obliquely arranged with respect to the screen;
- wherein the plurality of cameras is arranged with respect to the screen such that angles between capturing directions of the plurality of cameras and a screen plane are between 5° and 85°;
- wherein the screen is a scintillator screen,
- wherein the capturing directions are perpendicular to objective planes of the plurality of cameras.
The image capturing apparatus according to 1, wherein at least one of the plurality of cameras is arranged behind the screen.
A method for capturing a screen, comprising:
- capturing the screen with a plurality of cameras via a plurality of mirrors;
- wherein the plurality of mirrors and the plurality of cameras are arranged such that the plurality of cameras each capture a portion of the screen via a respective one of the plurality of mirrors, respectively, and
- wherein the plurality of cameras is arranged obliquely with respect to the screen;
- wherein the multitude of cameras is arranged with respect to the screen such that angles between capturing directions of the plurality of cameras and a screen plane are between 5° and 85°;
- wherein the screen is a scintillator screen,
- wherein the capturing directions are perpendicular to objective planes of the plurality of cameras.
A non-transitory digital storage medium having a computer program stored thereon to perform the method for capturing a screen, comprising:
- capturing the screen with a plurality of cameras via a plurality of mirrors;
- wherein the plurality of mirrors and the plurality of cameras are arranged such that the plurality of cameras each capture a portion of the screen via a respective one of the plurality of mirrors, respectively, and
- wherein the plurality of cameras is arranged obliquely with respect to the screen;
- wherein the multitude of cameras is arranged with respect to the screen such that angles between capturing directions of the plurality of cameras and a screen plane are between 5° and 85°;
- wherein the screen is a scintillator screen,
- wherein the capturing directions are perpendicular to objective planes of the plurality of cameras,
- when said computer program is run by a computer.
