Imaging apparatus, control method of imaging apparatus, interchangeable lens and lens-interchangeable type imaging apparatus body

摘要

An imaging apparatus includes: a lens-interchangeable type imaging apparatus body which includes a solid-state imaging device; and an interchangeable lens as defined herein; and the interchangeable lens is provided with a first storage portion which stores individual difference information about brightness of the interchangeable lens; and the lens-interchangeable type imaging apparatus body is provided with a second storage portion which stores information about a change of incident light sensitivity of the solid-state imaging device relative to each diaphragm value, and a control portion which uses the individual difference information about the brightness read from the first storage portion of the mounted interchangeable lens and the information about the change of the sensitivity in the second storage portion to thereby correct exposure at a time of imaging the photographic subject.

1. An imaging apparatus comprising: a lens-interchangeable type imaging apparatus body which comprises a solid-state imaging device; and an interchangeable lens which is detachably mounted on the lens-interchangeable type imaging apparatus body and which uses a diaphragm to adjust incident light from a photographic subject and uses a lens system to form an image of the incident light on a light receiving surface of the solid-state imaging device; wherein:
the interchangeable lens is provided with a first storage portion which stores individual difference information about brightness of the interchangeable lens, wherein said difference information indicates whether the brightness of the interchangeable lens is deviated from a design value; the lens-interchangeable type imaging apparatus body is provided with a second storage portion which stores information about a change of incident light sensitivity of the solid-state imaging device relative to each diaphragm value, and a control portion which uses the individual difference information about the brightness read from the first storage portion of the mounted interchangeable lens and the information about the change of the sensitivity in the second storage portion to thereby correct exposure at a time of imaging the photographic subject; and the individual difference information stored in the first storage portion is stored after classified into individual difference information when the diaphragm is driven to an open aperture side and individual difference information when the diaphragm is driven to a small aperture side.
