Abstract:
In a focus control apparatus, an acquisition unit periodically acquires a pair of focus detection signals, a focus detection unit detects a focus state of a first area using a phase difference and, in a case where the focus state of the first area is not within a first range, detects a focus state using a phase difference in a second area arranged in a periphery of the first area, and a control unit controls to perform focus control. The focus control is performed based on the focus state of the second area if it is within a second range and, if a subject exists on a near side, focus control is performed based on the focus state of the first area regardless of the focus state of the second area being detected or not.

Claim (Index 17):
A focus control method comprising:\n periodically acquiring image signals from an image sensor so as to be able to obtain a pair of focus detection signals having parallax; detecting a focus state of a predetermined first area using a phase difference between the pair of focus detection signals; in a case where the focus state of the first area is not within a predetermined first range, detecting a focus state using a phase difference between the pair of focus detection signals obtained from a second area arranged in a periphery of the first area; controlling to perform focus control based on the focus state of the second area in a case where the focus state of the second area is within a predetermined second range; and in a case where it is determined that a subject exists on a near side based on the focus state of the first area, controlling to perform focus control based on the focus state of the first area regardless of the focus state of the second area being detected or not.
