Title:
CONTROL DEVICE, IMAGING APPARATUS, CONTROL METHOD, AND PROGRAM
Document Type and Number:
Japanese Patent JP2021076777
Kind Code:
A
Abstract:
To provide a control device capable of swiftly and precisely performing focus control even when the imaging surface is raised.SOLUTION: A control device (100) includes: acquisition means (115) that acquires optical information; tilt control means (116) that controls the tilt angle; and calculation means (112) that calculates the amount of image shift calculated by the phase difference detection method based on a signal from the imaging element and calculates the defocus amount based on the image shift amount and conversion coefficient. The calculation means changes at least one of signal correction amount and conversion factor based on the optical information and the tilt angle.SELECTED DRAWING: Figure 1
