Image pickup apparatus, method for controlling the same, and storage medium

摘要

An image pickup apparatus includes an imaging unit configured to sequentially acquire an imaging signal while a focus lens is moving, a generation unit configured to generate a focus signal by using the imaging signal, and a control unit configured to control movement of the focus lens. The control unit performs a first operation for driving the focus lens in one direction in a range including a first area and a second area which is farther from a peak position of the focus signal than the first area. In the first operation, the control unit sets a focusing speed to a first speed when the focus lens is in the first area. When a predetermined condition is satisfied in the first operation, the control unit sets a focusing speed to a second speed faster than the first speed when the focus lens is in the second area.

1. An image pickup apparatus comprising:
an imaging unit configured to sequentially acquire an imaging signal while a focus lens is moving; a generation unit configured to generate a focus signal by using a high frequency component of the imaging signal; and a control unit configured to control movement of the focus lens based on the focus signal; wherein the control unit performs a first operation for driving the focus lens in one direction in a range including a first area and a second area which is farther from a peak position of the focus signal than the first area, wherein, in the first operation, the control unit sets a driving speed of the focus lens to a first speed when the focus lens is in the first area, wherein, when a predetermined condition is satisfied in the first operation, the control unit sets a driving speed of the focus lens to a second speed faster than the first speed when the focus lens is in the second area, and wherein, when a gradient of the focus signal with respect to a position of the focus lens exceeds a first predetermined value while driving the focus lens at the second speed, the control unit changes the driving speed of the focus lens to the first speed.
