Abstract:
1. An imaging device comprising: imaging means for obtaining an image signal relating to a subject; driving means for driving a focus lens; first detecting means for performing focus detection based on a contrast detection method to detect an in-focus position of the focus lens; second detecting means for performing focus detection based on a phase difference detection method, while the focus lens is being driven by the driving means toward the in-focus position, to execute a provisional position detection process of detecting a provisional in-focus position of the focus lens; and in-focus control means for controlling the driving means to drive the focus lens to pass through the provisional in-focus position and then return to the in-focus position, wherein the first detecting means includes wherein the in-focus control means includes the focus information obtaining process and the provisional position detection process are performed in parallel, and the focus information obtaining process is started before the provisional in-focus position is detected in the provisional position detection process.
