Image capturing apparatus and image processing method

摘要

An image processing apparatus includes a geometric converter configured to perform a geometric conversion process to a first frame image among frame images that are sequentially generated through imaging, based on motion information obtained by using a motion detector sensor, a motion vector detector configured to detect a motion vector between a geometric conversion image obtained through the geometric conversion process and a second frame image that has not undergone the geometric conversion process, an image stabilization parameter calculator configured to calculate an image stabilization parameter for different motions by using the motion information and the motion vector, and a stabilized image generator configured to generate a stabilized image through a deformation process to the second frame image or a frame image generated subsequent to the second frame image by utilizing the image stabilization parameter.

1. An image capturing apparatus comprising:
an image sensor configured to sequentially generate frame images; a first shake detector configured to detect rotational motion amount in a pitch direction and a yaw direction of the image capturing apparatus; a second shake detector configured to detect a motion vector based on the frame images; and a geometric deformation processing unit configured to sequentially generate output images by calculating a rotational motion around an optical axis and a motion amount in a translation direction based on the motion vector and performing a geometric deformation process for the frame images for each motion component of a motion of the image capturing apparatus based on the rotational motion around the optical axis, the motion amount in the translation direction, and the rotational motion amount in the pitch direction and the yaw direction, wherein the geometric deformation processing unit sequentially generates the output images by generating, as an initial image among the output images that have been sequentially generated, an image where the geometric deformation process has been performed based on the rotational motion amount in the pitch direction and the yaw direction and generating, as images generated subsequent to the initial image among the output images that have been sequentially generated, images where the geometric deformation process has been performed based on the rotational motion around the optical axis and the motion amount in the translation direction and the rotational motion amount in the pitch direction and the yaw direction.
