Abstract
Disclosed is an apparatus that executes, on second image data obtained by executing demosaic processing on first image data, adjustment processing using a first correction value to obtain third image data, wherein the first correction value is not dependent on the second image data. The apparatus estimates, based on the third image data, information relating to an ambient illuminant of a capturing scene of the first image data. The apparatus obtains, based on the estimated information relating to the ambient illuminant and on the second image data, a second correction value to be used for execution of adjustment processing on the second image data.
Claims19
An apparatus comprising one or more processors that execute a program stored in a memory and thereby cause the one or more processors to:
- execute, on second image data obtained by executing demosaic processing on first image data, adjustment processing using a first correction value to obtain third image data, wherein the first correction value is not dependent on the second image data;
- estimate, based on the third image data, information relating to an ambient illuminant of a capturing scene of the first image data;
- and
- obtain, based on the estimated information relating to the ambient illuminant and on the second image data, a second correction value to be used for execution of adjustment processing on the second image data.
An apparatus comprising:
- an image sensor;
- and
- an apparatus comprising one or more processors that execute a program stored in a memory and thereby cause the one or more processors to:
- execute, on second image data obtained by executing demosaic processing on first image data, adjustment processing using a first correction value to obtain third image data, wherein the first correction value is not dependent on the second image data;
- estimate, based on the third image data, information relating to an ambient illuminant of a capturing scene of the first image data;
- and
- obtain, based on the estimated information relating to the ambient illuminant and on the second image data, a second correction value to be used for execution of adjustment processing on the second image data,
- wherein after demosaic processing is executed on the first image data captured using the image sensor, adjustment processing is executed on the first image data using the second correction value obtained by the apparatus.
A method to be executed by an apparatus, the method comprising:
- executing, on second image data obtained by executing demosaic processing on first image data, adjustment processing using a first correction value to obtain third image data, wherein the first correction value to obtain third image data, wherein the first correction value is not dependent on the second image data;
- estimating, based on the third image data, information relating to an ambient illuminant of a capturing scene of the first image data;
- and
- obtaining, based on the estimated information relating to the ambient illuminant and on the second image data, a second correction value to be used for execution of adjustment processing on the second image data.
A non-transitory computer-readable medium storing a program for causing a computer to execute a method comprising:
- executing, on second image data obtained by executing demosaic processing on first image data, adjustment processing using a first correction value to obtain third image data, wherein the first correction value to obtain third image data, wherein the first correction value is not dependent on the second image data;
- estimating, based on the third image data, information relating to an ambient illuminant of a capturing scene of the first image data;
- and
- obtaining, based on the estimated information relating to the ambient illuminant and on the second image data, a second correction value to be used for execution of adjustment processing on the second image data.
