Title:
IMAGING DEVICE AND METHOD FOR CONTROLLING THE SAME
Document Type and Number:
Japanese Patent JP2016045322
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To establish highly accurate focus detection and the suppression of deterioration in image quality in an imaging device using an imaging element having focus detection pixels.SOLUTION: The imaging device is configured to calculate a first correction value for correcting an image deviation amount between the output signals of focus detection pixels on the basis of a plurality of image deviation amounts to be obtained on the basis of the output signals of imaging pixels positioned at a periphery of the focus detection pixels, and to calculate the defocus amount of an imaging optical system on the basis of the image deviation amount corrected by the first correction value.SELECTED DRAWING: Figure 12
