摘要： An image stabilization control apparatus including a mechanism which causes a vibration when the mechanism moves is disclosed. The apparatus comprises a vibration correction unit configured to correct image shake occurring due to vibration applied to the image stabilization control apparatus. A correction value of an angular velocity of the vibration is calculated based on signals based on the angular velocity and an acceleration of the vibration, frequency bands of the signals are narrowed. During the mechanism is moving, the image shake is corrected by driving the vibration correction unit based on the angular velocity of the vibration which is corrected by the corrected value calculated before the mechanism moves.

摘要： An image capture apparatus and control method thereof that improve focus detection accuracy in scenes that have low luminance, contrast, and the like is disclosed. The image capture apparatus has a focus detection mode suited to scenes that have low luminance, contrast, and the like. In this focus detection mode, the focus detection is carried out on the basis of a frequency component extracted from an image signal to which a coefficient for correcting intensity differences between color components is not applied, or to which a coefficient having a lower difference among color components than the computed coefficient has been applied.
