Publication number: 20220270264Abstract: An imaging device includes a subject detection unit that detects a subject with respect to an input image. The subject detection unit detects at least two parts within the image and determines a priority part among the detected parts. The subject detection unit performs a region extension process of extending the determined priority part to thereby extend a region from the priority part in a direction of another detected part. In detection of a plurality of parts, a part that cannot be detected is also handled as an extended region of a detection part. Thereby, if a user designates a region erroneously, the imaging device can determine that the user has designated the region when the designated region is included in the extended region.Type: ApplicationFiled: February 14, 2022Publication date: August 25, 2022Inventor: Yuta Kawamura

Patent number: 10447928Abstract: The present invention has an object to reduce occurrence of a state where a frame image with no visible subject has been generated during generation of a moving image with reduced variation in imaging trajectory. A camera trajectory estimating unit estimates an imaging trajectory during taking of a first moving image, from the first moving image. A camera trajectory correcting unit corrects a trajectory variation in the estimated imaging trajectory. An output image generating unit generates a second moving image corresponding to the corrected imaging trajectory, from the first moving image. Here, the camera trajectory correcting unit sets at least one reference point from the first moving image, and corrects the imaging trajectory so as to cause the reference point in frame images constituting the second moving image to have a position residing within a predetermined range in the frame image.Type: GrantFiled: May 30, 2017Date of Patent: October 15, 2019Assignee: CANON KABUSHIKI KAISHAInventor: Yuta Kawamura
