Abstract
Abstract A blurring motion detection device and method to determine an improved blurring motion zero reference value. The device includes a storage unit to store averaged blurring motion data based on an average of successive blurring motion data, with new blurring motion data being more recent in time than old blurring motion data. A selection unit filters out anomalous blurring motion data by selecting the blurring motion data within a deviation range from an average of the stored blurring motion data. The deviation range may include a first deviation range for the old blurring data which is set to be smaller than a second deviation range for the new blurring motion data. The deviation range may also be defined by a decision function which gradually widens the deviation range for the new blurring motion data. A calculation unit calculates the blurring motion zero reference value based on the blurring motion data within the deviation range. The calculation of the average of the successive blurring motion data and the blurring motion zero reference value may use weighted blurring motion data in which the new blurring motion data has a greater weight than the old blurring motion data.
