Title: IMAGING DEVICE AND FOCUSING CONTROL METHOD
Abstract:
This imaging device and focusing control method are capable of improving the moving body prediction accuracy while reducing the amount of calculations in moving body prediction used when continuously focusing on a moving subject. A system control unit (11) predicts the subject distance in imaging processing of the third frame from information about the subject distance obtained in imaging processing of the first frame and imaging processing of the second frame, calculates the error with respect to the predicted subject distance from information about the maximum error with respect to the calculated focus lens position, and if the error in the subject distance is large, then the lens is driven on the basis of the predicted focus lens position and not on the basis of focusing control based on the predicted subject distance.
