IMAGE CAPTURING APPARATUS

摘要

An image capturing apparatus includes a main image capturing system configured to capture an object image formed by a main optical system that can vary a magnification, a first sub capturing system configured to capture an object image formed by a first sub optical system having an angle of view equal to or wider than that at a wide-angle end of the main optical system, and a second sub capturing system configured to capture an object image formed by a second sub optical system having an angle of view narrower than that at a wide-angle end and equal to or wider than that at a telephoto end of the main optical system. An optical barrel configured to hold the main optical system can be retracted relative to a body of the image capturing apparatus. A predetermined condition is satisfied.

1. An image capturing apparatus comprising:
a main image capturing system configured to capture an object image formed by a main optical system that can vary a magnification; a first sub capturing system configured to capture an object image formed by a first sub optical system having an angle of view equal to or wider than that at a wide-angle end of the main optical system; and a second sub capturing system configured to capture an object image formed by a second sub optical system having an angle of view narrower than that at the wide-angle end of the main optical system and equal to or wider than that at a telephoto end of the main optical system, wherein an optical barrel configured to hold the main optical system is retractable relative to a body of the image capturing apparatus, and the first sub optical system and the second sub optical system are provided to the body, wherein where an i-th denotes first or second, and an i-th inter-axis direction is a direction in which an optical axis of the main optical system is separated from one of an optical axis of the first sub optical system and an optical axis of the second sub optical system, and wherein20≥LijMjtanω1≥130≥NfttanΩtare satisfied, where Ωt is a half angle of view in a second inter-axis direction at the telephoto end of the main optical system, ft is a focal length at the telephoto end of the main optical system, N is an inter-axis distance between the main optical system and the second sub optical system, and ωi is a half angle of view in the i-th inter-axis direction of the i-th sub optical system among the first sub optical system and the second sub optical system, Lij is a distance between the optical axis of the i-th sub optical system and an outer circumferential surface of a j-th barrel segment from the body in the optical barrel in the i-th inter-axis direction, and Mj is an extension amount of the j-th barrel segment relative to an optical surface closest to an object side in the first sub optical system and the second sub optical system.
