Abstract
The image pickup apparatus includes a memory storing first tracking data indicating a positional relationship of a magnification-varying lens and a correction lens and second tracking data indicating a positional relationship of the magnification-varying lens and an image sensor. A controller moves the correction lens and the image sensor using the first and second tracking data. An in-focus position detector detects an in-focus position using an output from the image sensor. A tracking adjuster obtains an adjustment value for adjusting the first tracking data, by using a difference between the detected in-focus position in a state where the magnification-varying lens is located at a first zoom position and the image sensor is located at a position in the second tracking data corresponding to the first zoom position and a position of the correction lens in the first tracking data corresponding to the first zoom position.
