Imaging device and control method therefor using shift direction calculation

A control method of an imaging device including

• an imaging optical system,
• a processor configured to perform a focus adjustment operation of the imaging optical system,
• an imaging element that generates a normal image by performing photoelectric conversion on a subject image from the imaging optical system, and generates first and second imaging signals by performing photoelectric conversion on each of first and second rays which are formed by performing pupil division on the subject image,
• the processor further configured to:
• generate a defocus image, which indicates an amount of defocus of the imaging optical system, on the basis of the first and second imaging signals, and
• a finder section, including a finder objecting window, that is configured to be capable of observing the subject image or the normal image in an observation area,
• the control method comprising:
• an eye position detection step of detecting a position of an eye of a photographer who is in contact with the finder section;
• a shift direction calculation step of calculating a direction of shift of the position of the eye with respect to a specific position in the observation area, on the basis of the position of the eye detected by the eye position detection step;
• and
• a finder display control step of displaying the defocus image in an area, which is opposed to the direction of shift with respect to the specific position in the observation area, in the observation area.
