IMAGING DEVICE, IMAGING DEVICE BODY, AND LENS BARREL

摘要

An imaging device includes an APD filter. A first program diagram is selected in a case in which the APD filter is not disposed, and a second program diagram is selected in a case in which the APD filter is disposed. A set of an imaging diaphragm value AV and an imaging shutter speed TV is determined on the basis of an exposure value obtained from a photometric value obtained from a photometric unit. The first program diagram is a multiple-stage diaphragm type program diagram. In the first program diagram, diaphragm values AV take discrete values at an interval of a first value. In the second program diagram, a part of corrected diaphragm values, which are obtained by correcting diaphragm values of the first program diagram on the basis of optical characteristics of the APD filter, are thinned out so that each interval has at least a second value.

主权项

1. An imaging device comprising:
an imaging element that photoelectrically converts an incident ray and outputs an imaging signal; a diaphragm that adjusts the amount of the incident ray; a photometric unit that performs photometry on the basis of the imaging signal; an apodization filter that is disposed on a light path of the incident ray; a program diagram storage unit that stores a first program diagram in which diaphragm values take discrete values at an interval of a first value, and a second program diagram in which a part of corrected diaphragm values, which are obtained by correcting the diaphragm values of the first program diagram on the basis of optical characteristics of the apodization filter, are thinned out so that each interval has at least a second value; an imaging exposure determining unit that selects the first program diagram in a case in which the apodization filter is not disposed, selects the second program diagram in a case in which the apodization filter is disposed, and determines a set of an imaging diaphragm value and an imaging shutter speed on the basis of an exposure value obtained from a photometric value obtained from the photometric unit; and an imaging exposure setting unit that sets an imaging exposure on the basis of the imaging diaphragm value and the imaging shutter speed determined by the imaging exposure determining unit.
