Picture stand

from Wikipedia, the free encyclopedia

The steadiness (English: image steadiness, French: fixité d'image) is a term used in film technology and a measure of the picture quality, so how quiet the screen looks. A good image position is characterized by a high degree of accuracy of registration of successive individual images . If the image is poorly positioned, the moving image trembles, wobbles or dances.

The quality of the image is checked in still settings .

The image status of a film presentation is influenced by various components:

The image status is made up of the total sum of the inaccuracies (errors) of the components. The camera , the copier and the projector make the greatest contribution to the image quality .

The subtotal error film and camera is z. B. determined by the accuracy of how the transport holes of the film fit together with the camera mechanics. Normal film is transported with a group of four pairs of holes per stroke.

The aim is to minimize all individual errors and the partial sum errors so that the total image stability error on the cinema projector is in the range of a hundredth of a millimeter.
