摘要： An automatic focusing apparatus repetitively detects a defocus amount of a photographing lens, discriminates whether or not an object is moving, and calculates a pursuit correction amount for a moving object on the basis of present and previous defocus amounts. When a non-moving object is discriminated, a drive amount of the lens is calculated on the basis of the present defocus amount, and when a moving object is discriminated the drive amount is calculated on the basis of a pursuit drive amount as a sum of the present defocus amount and the pursuit correction amount. A pursuit enable/disable determining device determines whether the drive amount is calculated on the basis of the discrimination result or on the basis of the present defocus amount. When a drive direction of the lens is reversed, the pursuit enable/disable determining device causes calculation of the drive amount of the photographing lens on the basis of the present defocus amount for driving the lens in a predetermined number of drive operations after the reversal.
