IMAGING DEVICE, IMAGING DEVICE BODY, AND LENS BARREL

摘要

An imaging device includes an APD filter. In a case in which the APD filter is disposed on a light path of an incident ray, an imaging exposure is determined using a corrected diaphragm value (T number) obtained by correcting a diaphragm value on the basis of optical characteristics of the APD filter and an imaging diaphragm, which is determined during the determination of the imaging exposure, is set. After that, a search interval SD is determined using a diaphragm value (F number), which is not yet corrected, in a first range in which the diaphragm value is larger than a specific value EF, without using the corrected diaphragm value (T number), and the search interval SD is determined by using the specific value as the diaphragm value in a second range in which the diaphragm value is equal to or smaller than the specific value EF.

主权项

1. An imaging device comprising:
a focus lens; an imaging element that photoelectrically converts an incident ray entering through the focus lens and outputs an imaging signal; a diaphragm that changes 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; an imaging exposure determining unit that determines an imaging exposure on the basis of a photometric value obtained from the photometric unit and determines the imaging exposure by using a corrected diaphragm value which is obtained by correcting a diaphragm value on the basis of optical characteristics of the apodization filter; a focus position detecting unit that moves the focus lens by search intervals and detects a focus position by calculating a focusing evaluation value for each search interval on the basis of the imaging signal; and a search interval determining unit that determines the search interval on the basis of a depth of focus depending on the diaphragm value, determines the search interval by using a diaphragm value, which is not yet corrected, in a first range in which the diaphragm value is larger than a specific value, and determines the search interval by using the specific value as the diaphragm value in a second range in which the diaphragm value is equal to or smaller than the specific value.
