发明名称 Image pickup apparatus and control method therefor
摘要 The image pickup apparatus includes a first detector detecting a first in-focus position by a phase difference detection method using paired image signals, a controller controlling position of a focus lens a basis of the first in-focus position to perform focusing, a second detector detecting a second in-focus position by a contrast detection method, a calculating part calculating a correction value for correcting the first in-focus position in image capturing on a basis of difference between the first and second in-focus positions, and a determining part determining a level of reliability of the first in-focus position. The controller calculates the correction value when the level of reliability is a first level, and to restrict the calculation of the correction value when the level of reliability is a second level lower than the first level.
