Click here for a printable version of this file

SECTION I - CLASS DEFINITION

This class deals with apparatus and corresponding processes for processing a sequence of images, in which the light variation composing the images may change with time (e.g., natural "live" scenes) for dynamic recording or reproducing of the sequence of images.

The processing involves the following steps: (a) Receiving a sequence of images from a local (e.g., camera, etc.) or remote source (e.g. broadcasting station, satellite, cable, etc.); (b) Converting the received sequence of images into a form suitable for dynamic storage, which form may or may not be reproduced later; or (c) Converting retrieved information from a dynamic storage medium into a sequence of images.

This class also deals with apparatus or processes for recording a single still or frame video using a dynamic recording device having relative movement between a transducer and a medium.

(1) This class includes apparatus and corresponding processes for making copies or editing of a recorded sequence of images falling within the above definition.
