Optical apparatus, image sensing device, and control methods thereof

An image sensing device including two optical systems arranged parallel at a predetermined spacing, comprising:

• two image sensing units;
• a cropping unit configured to generate images, having a predetermined size, cropped from two images obtained by said two image sensing units;
• a shake detection unit configured to detect a shake of said image sensing device, wherein said shake detection unit detects at least a rotational shake amount around an optical axis of said optical system;
• a displacement detection unit configured to detect a displacement amount in a plane perpendicular to the optical axis when rotation occurs around the optical axis of said optical system, for each of said two image sensing units;
• two correction units configured to correct image blur of optical images formed by said optical systems, based on the displacement amount detected by said displacement detection unit and the rotational shake amount detected by said shake detection unit;
• and
• a correction control unit configured to control such that in a plane perpendicular to the optical axis, two pixels having output centers of the images having the predetermined size on said two image sensors exist in the same position in a vertical direction, and a horizontal distance between said two image sensors is equal to the predetermined spacing.
