Patent Overview — US 7,589,852 B2

Title: Image capture apparatus and control method

Patent number: US 7,589,852 B2 (application US 11/000,485; publication US 2005/0141039 A1)

Inventor: Mitsuo Niida

Assignee: Canon Inc. (assigned to Canon Kabushiki Kaisha)

Key dates: Priority date 2003-12-03; filing date 2004-11-29; granted/publication date 2009-09-15. Listed legal status: "Expired – Fee Related," with an adjusted expiration of 2027-01-27 (the listing itself states this is an assumption, not a legal conclusion).

Purpose: Video captured by a camcorder is typically a collection of relatively short clips, so finding a desired clip to confirm content or edit afterwards requires searching. The stated object is to overcome drawbacks of prior arrangements and to let a user search for a desired clip (moving image) with a simple operation.

Plain-language scope: The apparatus has a first recording unit that records a moving image on a first recording medium, and a second recording unit that records, on a second recording medium, related information including information needed for searching for the moving image. A controlling unit transmits that related information, reproduced from the second recording medium, to a controller connected to the image capture apparatus, and searches for the moving image in response to a command transmitted from the controller. The disclosure also describes a corresponding control method for such an apparatus. The background discusses prior indexing approaches (indexes recorded on a separate medium or in an area next to the image area; recording times, contents, and titles in a semiconductor memory such as a flash memory inside a tape cassette; index images collectively recorded on tape with area information stored in the cassette memory) and cites Japanese Patent Laid-Open Nos. 7-154731, 7-154740, and 9-200674.

What the excerpt does not establish: The supplied text is a partial excerpt; it does not include the full claims, the complete detailed description, drawing content, or the full list of references. It therefore does not establish the precise claim scope, claim count, or any interpretation of claim terms beyond the summarized description above.

Assignment history

Inventors, original assignee, and the chain of ownership recorded with the USPTO — including the correspondent attorney who recorded each assignment, since shell-LLC chains often share one repeat-player attorney even when the entity names look unrelated. Surfaces NPE / patent-troll patterns: shell-entity transfers, known asserters in the chain, repeat correspondent fingerprints, pre-litigation assignments, and bankruptcy fire-sales.
