Method And Apparatus For Finding And Using Video Portions That Are Relevant To Adjacent Still Images

摘要

The invention relates to systems, methods, and computer readable media for responding to a user snapshot request by capturing anticipatory pre-snapshot image data as well as post-snapshot image data. The captured information may be used, depending upon the embodiment, to create archival image information and image presentation information that is both useful and pleasing to a user. The captured information may automatically be trimmed or edited to facilitate creating an enhanced image, such as a moving still image. Varying embodiments of the invention offer techniques for trimming and editing based upon the following: exposure, brightness, focus, white balance, detected motion of the camera, substantive image analysis, detected sound, image metadata, and/or any combination of the foregoing.

主权项

1) A method of producing an enhanced image comprising:
capturing an archive of image data comprising a plurality of image frames segmented as a pre-capture image sequence, a snapshot, and a post-capture image sequence, wherein the archival image data is captured by:
capturing the pre-capture image sequence,receiving a snapshot indication through a user interface, the snapshot indication received temporally after capturing at least a portion of the pre-capture image sequence,in response to the snapshot indication, capturing the snapshot image,capturing the post-capture image sequence, wherein at least a portion of the post-capture image sequence is captured temporally after receiving the snapshot indication, andcapturing contextual information associated with the pre-capture image sequence, the snapshot, and the post-capture image sequence, trimming or flagging the image frames of the pre-capture image sequence and the post-capture image sequence based upon an analysis of the contextual information and combined image frames of the archival image data, wherein the analysis comprises:
developing a target brightness level and an average brightness level,for each image frame, computing a ratio of the target brightness level with the average brightness level,trimming or flagging each pre-capture image frame and each post-capture image frame based upon a comparison of a ratio threshold to the image frame's ratio of target brightness level to average brightness level,determining a velocity or acceleration associated with each image frame,setting a threshold for velocity or acceleration based upon the velocity or acceleration of the snapshot image frame, andtrimming or flagging each pre-capture image frame based upon a comparison of its velocity or acceleration to the threshold for velocity or acceleration, and creating an enhanced image based upon the archival image data and the analysis.
