US Patent:

8438590, May 7, 2013

Filed:

Sep 22, 2010

Appl. No.:

12/887571

Inventors:

James E. Crenshaw - Burbank CA, US

Assignee:

General Instrument Corporation - Horsham PA

International Classification:

H04N 60/33

US Classification:

725 10, 725 12

Abstract:

A system and method of measuring audience reaction to media content includes obtaining images or other information of each individual of the audience as the individual views the content and analyzing the images or other information with software to generate emotional response source data for each individual. The emotional response source data identifies the emotion or emotions or change of emotions of the individual as interpreted by the software. The emotional response source data of the individuals is aggregated to identify a set of primary emotions of the audience, and thereafter, the emotional response source data is re-evaluated in view of the primary emotions to refine and more accurately classify the emotional responses of each individual of the audience.

Abstract:

In image processing system comprises an input configured to receive an image signal, the image signal including a plurality of frames of image data; and a processor configured to automatically determine an image classification based on at least one frame of the plurality of frames, and dynamically generate a mapping metadata based on the image classification. The processor includes determination circuitry configured to determine a content type for the image signal; segmentation circuitry configured to segment the image data into a plurality of feature item regions, based on the content type; extraction circuitry configured to extract at least one image aspect value for respective ones of the plurality of feature item regions.

H04N 7/01
H04N 19/46
H04N 19/157
H04N 5/14

Abstract:

Methods and systems for controlling judder are disclosed. Judder can be introduced locally within a picture, to restore a judder feeling which is normally expected in films. Judder metadata can be generated based on the input frames. The judder metadata includes base frame rate, judder control rate and display parameters, and can be used to control judder for different applications.

International Classification:

H04N 13/00

Abstract:

Methods and systems for enhancing motion estimation are disclosed for stereoscopic video sequences. The motion vector parameters and disparity values for consecutive frames may be calculated to estimate motion in a coherent manner between two channels, such as a left channel and a right channel in stereoscopic images. Occlusion handling is also applied to improve the estimation.

International Classification:

H04N 1/60
G06T 5/00
G06T 5/50

Abstract:

Video data with enhanced dynamic range are color graded for a first and a second reference display with different dynamic range characteristics to generate a first color-graded output, a second color graded output, and associated first and second sets of metadata. The first color-graded output and the two sets of metadata are transmitted from an encoder to a decoder to be displayed on a target display which may be different than the second reference display. At the receiver, a decoder interpolates between the first and second set of metadata to generate a third set of metadata which drives the display management process for displaying the received video data onto the target display. The second set of metadata of metadata may be represented as delta metadata values from the first set of metadata values.
