Abstract
An imaging apparatus includes an imaging device, an optical member that adjusts an amount of light of an object image incident on the imaging device, at least one memory storing a program, and at least one processor that when executing the program is configured to adjust transmittance of the optical member, amplify an image signal output when an image of an object is captured using the imaging device, and control exposure by changing an exposure condition including an exposure index.
Claims13
An imaging apparatus, comprising:
- an imaging device;
- an optical member configured to adjust an amount of light of an object image incident on the imaging device;
- at least one memory storing a program;
- and
- at least one processor that when executing the program is configured to:
- adjust transmittance of the optical member;
- amplify an image signal output when an image of an object is captured using the imaging device;
- and
- control exposure by changing an exposure condition including an exposure index,
- wherein a value of the exposure index is settable by a user from predetermined discrete values,
- wherein the exposure condition includes an aperture value and an accumulation time which are different from the exposure index, and
- wherein a combination of an amplification factor of the image signal to be used in amplifying the image signal and the transmittance of the optical member is predetermined for each exposure index settable by the user.
A method of controlling an imaging apparatus that includes an imaging device and an optical member configured to adjust an amount of light of an object image incident on the imaging device, the method comprising:
- adjusting transmittance of the optical member;
- amplifying an image signal output when an image of an object is captured with use of the imaging device;
- and
- controlling exposure by changing an exposure condition including an exposure index,
- wherein a value of the exposure index is settable by a user from predetermined discrete values,
- wherein the exposure condition includes an aperture value and an accumulation time which are different from the exposure index, and
- wherein a combination of an amplification factor of the image signal and the transmittance of the optical member is predetermined for each exposure index settable by the user.
A non-transitory computer-readable recording medium storing a program for causing a processor to execute a method of controlling an imaging apparatus that includes an imaging device and an optical member configured to adjust an amount of light of an object image incident on the imaging device, the control method comprising:
- adjusting transmittance of the optical member;
- amplifying an image signal output when an image of an object is captured with use of the imaging device;
- and
- controlling exposure by changing an exposure condition including an exposure index,
- wherein a value of the exposure index is settable by a user from predetermined discrete values,
- wherein the exposure condition includes an aperture value and an accumulation time which are different from the exposure index, and
- wherein a combination of an amplification factor of the image signal and the transmittance of the optical member is predetermined for each exposure index settable by the user.
