Filed: 2000-08-23
Abstract: PROBLEM TO BE SOLVED: To provide an automatic focusing device capable of rapidly performing focusing even in the case of using such a photographing lens that a conversion coefficient for calculating the number of pulses from defocus amount is changed according to a photographing distance. SOLUTION: The number of updated pulses obtained by overlapping integration in the midst of driving a focusing lens is corrected according to relation between the moving amount of an image surface and the real moving amount of the lens. When the moving amount of the image surface is smaller than the real moving amount of the lens, the number of updated pulses is corrected to be large, so that the focusing lens is prevented from advancing insufficiently. When the moving amount of the image surface is larger than the real moving amount of the lens, the number of updated pulses is corrected to be small, so that the focusing lens is prevented from advancing excessively. The corrected number of updated pulses is replaced as the number of remaining pulses, and the driving of the focusing lens is continued.
