焦点検出装置および撮像装置
Document Type and Number:
Japanese Patent JP7014255
Kind Code:
B2
Abstract:
To suppress occurrence of drive sound and vibration caused by driving a focus lens during focus detection processing in a hill-climbing contrast method.SOLUTION: A focus lens 210 is driven in a predetermined direction to perform hill-climbing operation of focus evaluation values of contrast AF. When a peak of the focus evaluation values is detected, image plane displacement caused by overshoot of the focus lens 210 is corrected by driving a wobbling lens 220 and an imaging element in an optical axis direction.SELECTED DRAWING: Figure 1
