IMAGE DATA PROCESSING OR GENERATION, IN GENERAL ( specially adapted for particular applications, see the relevant subclasses, e.g. G06K, G09G, H04N )
NOTE
-
This subclass covers:
- 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;
- arrangements for analysing the geometric attributes of an image of an object.

This subclass does not cover:
- reading or recognising printed or written characters or recognising patterns, e.g. fingerprints, which is covered by subclass G06K;
- modification of image data to allow display using multiple viewports, which is covered by subclass G09G;
- circuits for generating functions for visual indicators, which are covered by subclass G09G;
- scanning of documents or the like in pictorial communication, which is covered by subclass H04N.

The following IPC groups are not used in the CPC scheme. Subject matter covered by these groups is classified in the following CPC groups:
