kuvapinnalta

Kuvapinnalta is a Finnish term meaning “from the image plane.” It is formed from kuvapinta (image plane) plus the ablative suffix -lta, which marks origin. The phrase is used chiefly in technical Finnish to refer to viewpoints, references, or operations tied to the image plane rather than to the real three‑dimensional scene.

Typical contexts for kuvapinnalta include optics, photography, cinematography, and computer graphics. In these fields, the image plane is the surface where an image is formed, captured by a sensor or displayed. Therefore, kuvapinnalta describes actions performed with respect to that plane—such as projections, calibrations, sampling, or coordinate transformations in image space—or a viewpoint located on or relative to the image plane.

Because it is a specialized expression, kuvapinnalta seldom appears outside professional or academic texts. Its exact meaning depends on context: it can denote a geometric projection, a sensor/display plane, or a perceptual standpoint associated with the image plane. When encountered, readers should interpret the phrase from the surrounding technical discussion to determine whether the reference is to measurement, reconstruction, or perspective relative to the image plane.

Example: Kuvapinnalta katsottuna reuna näyttää vääristyneeltä. (From the image plane, the edge appears distorted.)
