| 摘要 |
The invention relates to a device including a colour separation prism, comprising at least two image sensors (12, 13, 14) whose sensor surfaces are substantially of the shape of a rectangular parallelogram, and a colour separation prism (1) whose front surface (2) of a functional part is planar and substantially of the shape of a rectangular parallelogram, whereby the front surface of the functional part of the colour separation prism has a first side length (l1) and a second side length (l 2) perpendicular thereto. In the device of the invention, the first side length (l1) of the front surface of the functional part of the colour separation prism is substantial ly shorter than the second side length (l2).
