  • Publication number: 20190052809
    Abstract: An imaging apparatus includes an angular velocity sensor configured to detect shaking and a motion vector detection unit configured to detect movement in a captured image. A shift lens group constitutes a correction optical system configured to correct an image blur due to shaking exerted on the imaging apparatus. A position sensor detects a position of the shift lens group. A distance acquiring unit acquires distance information associated with the captured image. When an angular velocity of an object is calculated on the basis of a shaking detection signal, a movement vector, position information of the shift lens group, and the distance information, an object angular velocity calculating unit calculates an amount of movement of the object by adding position information of the shift lens group synchronized with a detection period of the movement vector to movement vector information and calculates an amount of shaking correction.

  • Publication number: 20180103207
    Abstract: An imaging device detects a shake detection signal and an amount of motion of an image within a photography screen when a panning assist mode that supports panning is set. A search range of a face detection position of a subject is set (S510), and a process of changing a calculation process of a subject vector (motion vector) is performed based on a face detection result. If the face detection position of the subject is acquired (Yes in S511 and S512), a first calculation process in which a subject vector is calculated from motion vectors within a first detection range based on the face detection position (S513) is performed. In addition, if the face detection position of the subject is not acquired (No in S511) and a subject vector can be detected (Yes in S514), a second calculation process in which a subject vector is calculated from the motion vectors within a second detection range based on a focus detection frame set within the photography screen is performed (S515).
