Abstract: A photographic processing apparatus comprising two or more chambers having baths for processing photographic material and having at least one immersion roller in each bath for immersing and conveying the photographic material. The immersion roller may be driven by a magnetic coupling arrangement.

Abstract: A low volume photographic material processing apparatus that utilizes a narrow horizontal processing channel with an upturned entrance and exit to contain processing solution within the channel. The apparatus accurately maintains the processing solution level by keeping the upper surface of the processing solution below the high impingement devices solution exit.

Abstract: Selecting of particular image lines for composition of range image such that a composition and evaluation of range image is possible in real time actually corresponds to the imaging of a TV or video camera. The image field is scanned column by column and the contents of the column (all lines) are read in parallel. After digitizing the content of the column, a selection logic selects a particular imaging dot within each of the columns. Using the principles of triangulation, the line position of the dot selected is identified by a multibit binary data word is vertical position in representation of the distance from the camera or the light strip source.
