Kuvataso

Kuvataso is a Finnish term that translates roughly to "image plane" or "picture plane" in English. It is used in optics, photography, and computer graphics to denote the two-dimensional surface on which an image is formed or recorded. In traditional optics and photography, the kuvataso corresponds to the film or sensor plane inside a camera, where light that has passed through the lens is captured to create a two-dimensional representation of the scene.

In geometrical optics and graphics, the kuvataso is the plane onto which three-dimensional points are projected in a perspective projection. Its position and orientation relative to the camera, together with the focal length and other intrinsic parameters, determine how a 3D scene is mapped to the 2D image. In computer graphics, the kuvataso is treated as the image plane used for rendering; the projection matrix converts coordinates from camera or world space to coordinates on this plane, which then become screen coordinates.

The term is common in Finnish discussions of optics, photography, and 3D rendering, and is often used interchangeably with image plane or sensor plane in technical contexts. Terminology can vary by field, and in image editing software Finnish speakers may refer to different concepts as layers (tasot) rather than kuvataso. Overall, kuvataso designates the fundamental surface where an image is captured or projected in both physical and digital imaging workflows.
