  • Publication number: 20180020164
    Abstract: A difference between a movement represented by a signal representing a movement of an image capture apparatus and each of motion vectors detected between images is calculated. Then, a motion vector determined to have a temporal variation in the difference smaller than a preset threshold value is determined as a background area motion vector. Also, from among motion vectors other than the background area motion vector, a subject area motion vector is determined. Then, image stabilization is controlled based on the subject area motion vector. It is thereby possible to enhance the accuracy of distinguishing motion vectors.

  • Patent number: RE45692
    Abstract: An automatic focusing apparatus performs focusing using a first automatic focusing method in which lens drive control is performed based on a focus signal so that a focus lens is moved to an in-focus point, and a second automatic focusing method in which lens drive control is performed based on information corresponding to an object distance so that the focus lens is moved to an in-focus point. The direction in which the focus lens is moved to the in-focus point according to the second automatic focusing method is compared with the direction in which the focus lens is moved to the in-focus point according to the first automatic focusing method. Based on the result, it is determined whether to perform the lens drive control according to the second automatic focusing method.
