Abstract
A focus adjusting device in which, when a detecting unit that detects an object image to be focused from a picked up image is capable of detecting the object image to be focused, a setting unit that sets a focus detection area when a focused state of an image pickup optical system is detected sets a second focus detection area after setting a first focus detection area and in accordance with the position of the first focus detection area, corresponding to the object image that is detected by the detecting unit and that is to be focused. Then, on the basis of signal outputs at the set focus detection area, the image pickup optical system is driven to perform focus adjustment.
