PROBLEM TO BE SOLVED: To provide a focal point adjustment device, camera system, and focal point adjustment method with which a conversion factor can be corrected to be accurate in individual focal point adjustment devices.SOLUTION: A focal point detection unit 205 calculates an interval value between two images (image phase difference information) on the basis of image data from a focal point detection pixel of an imaging element 201, and a CPU in a main body control unit 203 calculates a defocus amount y (S5), calculates a lens drive amount, and performs lens drive (S7). The main body control unit 203 corrects a conversion factor for calculating the defocus amount with a learning algorithm (S9). |
