Abstract
Light quantization of elemental areas of pictorial information by a plurality of contiguous light integrating tunnels, either with or without one of a group of different sampling-function array masks and/or printing-function array masks, is used to modify the original picture information for such purposes as subjectively providing a (1) more pleasing picture, (2) striking special display effects and (3) studying visual perception by the human visual system. Analog processor replaces expensive computer equipment which also required tedious programming, formerly required for producing similar modification of picture information.
Claims3
An analog optical processor for respectively quantizing the light of each elemental area of a light image manifesting pictorial information which is incident thereon, said analog optical processor comprising:
- a. a plurality of contiguous light integrating tunnels, each of which has substantially the same cross sectional dimensions and a length which is long relative to the cross sectional dimensions thereof and wherein each respective tunnel has reflective sides,
- b. a front diffuser covering the front surface of said plurality of contiguous light integrating tunnels through which said plurality of contiguous light integrating tunnels are illuminated by said incident light image,
- c. a rear diffuser covering the back surface of said plurality of contiguous light integrating tunnels through which light emerging from each of said contiguous light integrating tunnels passes,
- d. a printing-function array mask situated immediately behind said rear diffuser, said printing-function array mask including an individual element of said array corresponding to and in cooperative spaced relationship with each light integrating tunnel, all of said printing function array elements having a predetermined transmission characteristic, each said element comprising a point size hole, and
- e. a camera situated behind said printing-function array mask at a distance therefrom to be illuminated by light passing through the respective elements of said printing-function array mask, and means including a single input aperture situated in front of said camera, said camera including a lens for imaging the light passing through said input aperture in an image plane, and said camera incorporating a recording medium situated in a given plane spaced from said image plane by a given distance to derive an individual blur image of said input aperture on said recording medium for the light from each respective element of said printing-function array mask.
