Patent Summary

U.S. Patent Classes & Classifications Covered in this listing:

Class 715: Data Processing: Presentation Processing Of Document

This class provides for data processing means or steps wherein a) human perceptible elements of electronic information (i.e., text or graphics) are gathered, associated, created, formatted, edited, prepared, or otherwise processed in forming a unified collection of such information storable as a distinct entity, b) a users interaction with a computer system is used to control the presentation of display data; such interaction is interpreted and used by a data processor or computer architecture wherein system level elements of computation or data processing techniques are used prior to use with or in a specific display system, or c) a small program takes over a display screen if there are no keystrokes or mouse movements for a specified duration.

Class 386: Television Signal Processing For Dynamic Recording Or Reproducing

Apparatus and corresponding processes for processing a sequence of images, in which the light variation composing the images may change with time 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.

Subclass 515: Audio to video

Class 382: Image Analysis

This is the generic class for apparatus and corresponding methods for the automated analysis of an image or recognition of a pattern. Included herein are systems that transform an image for the purpose of (a) enhancing its visual quality prior to recognition, (b) locating and registering the image relative to a sensor or stored prototype, or reducing the amount of image data by discarding irrelevant data, and (c) measuring significant characteristics of the image.
