Abstract
An imaging apparatus includes an image sensor configured to photoelectrically convert an object image formed by an imaging optical system in at least three states in which positions of light sources configured to emit light are different from each other, and to output at least three image data, and a luminance distribution acquirer configured to acquire information on a plurality of luminance distributions of the image data based on common information on a common light amount distribution regarding the at least three states.
Claims19
An imaging apparatus comprising:
- an image sensor configured to photoelectrically convert an object image formed by an imaging optical system in at least three states in which positions of light sources configured to emit light are different from each other, and to output at least three image data;
- and
- a luminance distribution acquirer configured to acquire information on a plurality of luminance distributions of the image data based on common information on a common light amount distribution regarding the at least three states.
An accessory attachable to and detachable from an imaging apparatus comprising:
- a light emitter configured to individually emit light at least three different light source positions;
- and
- a communicator configured to transmit (a) common information on a common light amount distribution for the light source positions of the light emitter or (b) information that enables to acquiring the common information.
A processing apparatus comprising:
- a light amount distribution information acquirer configured to acquire common information on a common light amount distribution for at least three different light source positions;
- and
- a luminance distribution acquirer configured to acquire, based on the common information, information on the luminance distribution of at least three image data obtained by imaging in at least three states in which a position of a light source that emits light is different from each other.
A processing method comprising the steps of:
- acquiring common information on a common light amount distribution for at least three different light source positions;
- and
- acquiring, based on the common information, information on the luminance distribution of at least three image data obtained by imaging in at least three states in which a position of a light source that emits light is different from each other.
A storage medium storing a program that causes a computer to execute a processing method,
- wherein the processing method includes the steps of:
- acquiring common information on a common light amount distribution for at least three different light source positions;
- and
- acquiring, based on the common information, information on the luminance distribution of at least three image data obtained by imaging in at least three states in which a position of a light source that emits light is different from each other.
