发明名称 Imaging device detecting motion vector
摘要 An imaging device includes a first detection unit, a vector correction unit, and a second detection unit. The first detection unit is configured to detect a motion vector based on reference image data and input image data after aberration of a lens is corrected. The vector correction unit is configured to correct an error component included in the motion vector detected by the first detection unit according to an aberration characteristic of the lens. The error component is produced by aberration correction. The second detection unit is configured to set a search area of the motion vector based on the motion vector corrected by the vector correction unit and detect the motion vector in the search area.

主权项 1. An imaging apparatus comprising: an imaging unit that generates image data corresponding to an image captured through a lens unit; a processing unit that processes the image data and reference image data using aberration characteristic information indicating an aberration characteristic of the lens unit; a first detecting unit that uses the processed image data and the processed reference image data to detect a first motion vector; a modification unit that modifies the detected first motion vector using the aberration characteristic information to generate a second motion vector different from the first motion vector; a second detecting unit that uses the second motion vector, the image data, and the reference image data to detect a third motion vector; and an encoding unit that encodes the image data using the detected third motion vector instead of the first motion vector and the second motion vector.
