  • Patent number: 10848675
    Abstract: There is provided an image blur correction apparatus including a communication device configured to communicate with a correction amount determination apparatus that determines a second correction amount for correcting image blur of an image capturing apparatus based on shake occurring in the image capturing apparatus. A reception unit receives the second correction amount from the correction amount determination apparatus via the communication device. Based on the second correction amount, a control unit controls a second correction member configured to correct the image blur. An acquisition unit acquires a correction error of the second correction member caused by a communication delay of the second correction amount in the communication device. Based on the correction error, a third correction unit corrects the image blur by image processing to reduce the correction error.
