Problems solved by technology

Also, unlike speech recognition, various complications can arise when performing automatic visual recognition of segments of media content
The orientation of the image and extraneous images within the field of view can complicate efforts to capture an image or video segment through the viewfinder of a portable personal computing device

Embodiment Construction

[0028] There are occasions when media content (eg, text, images, video) being viewed needs to be identified and communicated by another device. The user is thereby able to use media content in a convenient manner. For example, a user can read media content, such as text-based news or entertainment articles contained in a printed periodical or displayed on a computer monitor. Similarly, media content may be graphical, such as schematic drawings or photographs. As another example, a user may watch a scene in which visual media content is being displayed. To quickly capture what is being viewed for later retrieval, users can conveniently use the camera function. To quickly capture and later query the full content of text-based or graphic articles or visual media content, users can use camera-enabled mobile devices (e.g., smartphones, portable game consoles, personal digital assistants, etc.) .

[0029] Various aspects will now be described with reference to the accompanying d...

Abstract

Automatic identification of media content is at least partially based upon visually capturing a still or video image of media content being presented to a user via another device. The media content can be further refined by determining location of the user, capturing an audio portion of the media content, date and time of the capture, or profile / behavioral characteristics of the user. Identifying the media content can require (1) distinguishing a rectangular illumination the corresponds to a video display; (2) decoding a watermark presented within the displayed image / video; (3) characterizing the presentation sufficiently for determining a particular time stamp or portion of a program; and (4) determining user setting preferences for viewing the program (e.g., close captioning, aspect ratio, language). Thus identified, the media content appropriately formatted can be received for continued presentation on a user interface of the mobile device.

Description

technical field [0001] The present invention relates to mobile operating environments, and more particularly, to visually identifying visual media content captured by a camera-enabled mobile device. Background technique [0002] For decades, the development of digital image processing has attempted to automate certain visual abilities, such as image recognition. Computer vision has attempted to identify obstacles for autonomous navigation. Optical character recognition relies on techniques such as detecting skew in images and performing character shape association. Surveillance systems attempt to recognize biometric data such as faces in order to maintain security. [0003] One example of image processing is generating a digital key signature for each known segment of a video broadcast program, which can then be matched by a digital key signature generated for an unknown segment. This technique is used by broadcast advertisers to automatically track to see what commercial...
