IMAGE DATA PROCESSING OR GENERATION, IN GENERAL (specially adapted for particular applications, see the relevant subclasses, e.g. G 06 K, G 09 G, H 04 N
) [6]
Notes
(1)
This subclass covers: [6]
-
arrangements for geometrically modelling objects, whether the final model is used for display of an image of the object or for some other purpose, such as manufacture of a corresponding object; [6]
-
arrangements for analysing the geometric attributes of an image of an object. [6]
(2)
This subclass does not cover: [6]
-
reading or recognising printed or written characters or recognising patterns, e.g. fingerprints, which is covered by subclass
G 06 K; [6]
-
modification of image data to allow display using multiple viewports, which is covered by subclass G 09 G; [6]
-
circuits for generating functions for visual indicators, which are covered by subclass G 09 G; [6]
-
scanning of documents or the like in pictorial communication, which is covered by subclass H 04 N. [6]
