A stereo camera comprising: a first imaging unit including a first imaging optical system including a wide angle optical system and a telephoto optical system having optical axes matching each other and disposed in different regions, and a first directivity sensor having a plurality of pixels that pupil-divide and selectively receive a light beam incident via the wide angle optical system and the telephoto optical system; a second imaging unit including a second imaging optical system having the same configuration as the first imaging optical system and a second directivity sensor having the same configuration as the first directivity sensor, the second imaging unit being disposed to be spaced from the first imaging unit by a baseline length; an image acquisition unit that acquires a first wide angle image and a second wide angle image, and a first telephoto image and a second telephoto image from the first directivity sensor and the second directivity sensor; a pan and tilt mechanism that rotationally moves the first imaging unit and the second imaging unit in a horizontal direction and a vertical direction; a pan and tilt control unit that controls the pan and tilt mechanism on the basis of the first wide angle image and the second wide angle image acquired by the image acquisition unit so that a main subject is captured on the respective optical axes of the first imaging optical system and the second imaging optical system; a distance information calculation unit that calculates at least distance information of the main subject on the basis of the first telephoto image and the second telephoto image acquired by the image acquisition unit, and a first focus adjustment unit that performs focus adjustment of the respective telephoto optical systems of the first imaging optical system and the second imaging optical system, wherein the first focus adjustment unit acquires distance information of the main subject on the basis of the amount of parallax in the first directivity sensor and the second directivity sensor of the main subject included in the first wide angle image and the second wide angle image acquired by the image acquisition unit, the baseline length, the optical axis directions of the first imaging optical system and the second imaging optical system, and a focal length of the wide angle optical system, and performs focus adjustment of the respective telephoto optical systems of the first imaging optical system and the second imaging optical system on the basis of the acquired distance information. a first imaging unit including a first imaging optical system including a wide angle optical system and a telephoto optical system having optical axes matching each other and disposed in different regions, and a first directivity sensor having a plurality of pixels that pupil-divide and selectively receive a light beam incident via the wide angle optical system and the telephoto optical system;
