SECTION I - CLASS DEFINITION

This class deals with generating, processing, transmitting or transiently displaying a sequence of images, either locally or remotely, in which the local light variations composing the images may change with time (e.g., natural "live" scenes) by methods involving the following steps:

Step 1. The scanning of an object or a scene by partitioning the object or scene into subareas of image information (e.g., pels or pixels) and generating therefrom an electrical signal representative of an image.

Step 2. The transient display of an object or a scene image by converting an electrical signal representative of the object image (i.e., video signal) into a visible image of the object.

In this class, the sequence of images is intended to portray motion with exception of special television type systems that produce a sequence of still images from a conventional television system (e.g., videophone, slow scan, film retrieval, and security systems). These special television systems normally select an image from a sequence of images of a conventional television system and normally use a transient display (e.g., CRT or liquid crystal).

Facsimile images are normally of a fixed scene (e.g., document) that do not form a sequence, cannot portray motion, and normally the display is fixed (e.g., hard copy). (See References to Other Classes, below.) In television recording, the sequence of images are dynamically recorded for later reproduction.

SUBCOMBINATIONS OF TELEVISION SYSTEMS

This class includes circuits specially designed for dealing with a peculiar component of the television signal (e.g., sync or chrominance), as distinct from merely signals of a particular frequency range.

Electrical circuits that are not specific to television which may constitute subcombinations of such apparatus are classified in the appropriate class for such circuits.

For a video camera or television receiver having a static storage device as subcombination, see Subclass References to the Current Class, below.

SECTION II - LINES WITH OTHER CLASSES AND WITHIN THIS CLASS

COMBINATIONS OF OTHER APPARATUS WHICH INCLUDE APPARATUS OF THIS CLASS

This class does not include the following subject matter:

1. Systems in which legible alphanumeric or like character forms are analyzed according to step 1 above to derive an electric signal from which the character is recognized by comparison with stored information are classified elsewhere. (See References to Other Classes, below.)

2. Systems for the direct photographic copying of an original picture in which an electric signal representative of a characteristic of the picture is derived and employed to modify the operation of the system are classified elsewhere. (See References to Other Classes, below.)

3. Systems for the reproduction, according to step 2, of images comprising alphanumeric or computer generated graphics and systems for the conversion of a computer generated signal into a television signal are classified elsewhere. (See References to Other Classes, below.)

4. Systems for the dynamic recording, or reproducing, of black and white television using a nonmagnetic medium, systems for the dynamic recording or reproducing of color television, and systems for photographing displayed images are classified elsewhere. (See References to Other Classes, below.)

5. Systems for the dynamic recording or reproducing of black and white images from magnetic media (e.g., magnetic tape) are classified elsewhere. (See References to Other Classes, below.)
