In an image pickup apparatus in which image stabilization is performed based on two shake detection methods including shake sensor and movement vector obtaining method, an accurate blur correction can be carried out by the movement vector obtaining method since shake components that are difficult to be detected by a shake sensor can be detected by the movement vector obtaining method. However, in shooting with low frame rate, the image blur due to high frequency vibration such as vehicle vibration cannot be corrected by the movement vector since the detectable frequency band narrows in high frequency. Therefore, it is necessary to optimize the combination of blur information from the angular velocity sensor and from the movement vector, in accordance with the frequency band detectable by the movement vector depending on change in frame rate. The combination ratio of blur correction based on blur information from angular velocity sensor, acceleration sensor or the like and blur correction based on movement vector is determined in accordance with frequency detectable by the movement vector which inevitably changes depending on frame rate. |
