Title:
撮像装置及び合焦制御方法
Document Type and Number:
Japanese Patent JP5750550
Kind Code:
B2
Abstract:
An imaging device, includes: a sensor including first phase difference detecting pixels arranged in a row direction and second phase difference detecting pixels arranged in the row direction; a defocus amount calculating unit which calculates a correlated amount of a first output signal group and a second output signal group while shifting the first output signal group and the second output signal group in the row direction by an arbitrary amount to calculate a defocus amount from a first shift amount of the first output signal group and the second output signal group when the correlated amount is at a maximum. The defocus amount calculating unit changes an upper limit of a shift amount of the first output signal group and the second output signal group in accordance with at least one of an F value, a focal distance, and a position of a focus lens.
