Patent ID: 8855479

Claim:
An imaging apparatus comprising: a focus state detection unit provided in an imaging element and detecting a phase difference; a signal processing unit for generating a focus adjustment signal based on the imaging signal outputted by the imaging element; and a control unit that acquires an in-focus lens position in accordance with a focus lens based on a focus deviation amount, the focus deviation amount calculated from a detection result of the focus state detection unit, calculates distance information related to the in-focus distance on the image screen, and controls the driving of the focus lens based on the distance information and the focus adjustment signal; wherein, when a difference between the in-focus lens position and the position of the focus lens at the current time exceeds a threshold, the control unit drives the focus lens to the in-focus lens position, and when the difference between the in-focus lens position and the position of the focus lens at the current time is less than or equal to the threshold, the control unit executes the in-focus control based on the focus adjustment signal, wherein the control unit sets a detection frame for executing the in-focus control based on the focus adjustment signal, the detection frame being set based on the distance information so that the proportion of the area within a predetermined depth of field is greater than the proportion of the area outside the predetermined depth of field, and wherein the focus adjustment signal is generated based on the imaging signal in the detection frame.
