Abstract:
An image blur correction apparatus includes an shooting state detecting portion that determines a shooting state of a first shooting state or a second shooting state based on an angular velocity signal, and a controller that performs an image blur correction using characteristics depending on a determination result of the shooting state determining portion, and the shooting state determining portion determines that the first shooting state has started when the angular velocity signal exceeds a first threshold value and exceeds a second threshold value having an opposite sign of the first threshold value within a predetermined time after exceeding the first threshold value, and determines that the first shooting state is continuously maintained when the angular velocity signal exceeds a third threshold value and exceeds a fourth threshold value that has an opposite sign of the third threshold value within the predetermined time after exceeding the third threshold value.
