Abstract
A capturing parameter and a capturing image are obtained by an image capturing device which uses the capturing parameter. Correction data, which corresponds to an optical transfer function of the image capturing device derived from the capturing parameter, and a noise amount of the capturing image dependent on the capturing parameter, is acquired to correct a blur of the capturing image. A first degree of correction by the correction data for a high noise amount is less than a second degree of correction by the correction data for a low noise amount.
Claims12
An image processing apparatus comprising:
- a first acquisition section configured to acquire a capturing parameter and a capturing image obtained by an image capturing device which uses the capturing parameter;
- a holding unit configured to hold a plurality of correction data in accordance with noise amounts;
- and
- a second acquisition section configured to acquire, corresponding to (a) an optical transfer function of the image capturing device derived from the capturing parameter and (b) an ISO sensitivity included in the capturing parameter, correction data among the plurality of correction data to correct a blur of the capturing image.
An image processing method performed by a processor, the method comprising:
- using the processor to perform the steps of:
- acquiring a capturing parameter and a capturing image obtained by an image capturing device which uses the capturing parameter;
- holding a plurality of correction data in accordance with noise amounts;
- and
- acquiring correction data, corresponding to (a) an optical transfer function of the image capturing device derived from the capturing parameter and (b) an ISO sensitivity included in the capturing parameter, among the plurality of correction data to correct a blur of the capturing image.
A non-transitory computer-readable medium storing a computer-executable program for causing a computer to perform an image processing method, the method comprising the steps of:
- acquiring a capturing parameter and a capturing image obtained by an image capturing device which uses the capturing parameter;
- holding a plurality of correction data in accordance with noise amounts;
- and
- acquiring correction data, corresponding to (a) an optical transfer function of the image capturing device derived from the capturing parameter and (b) an ISO sensitivity included in the capturing parameter, among the plurality of correction data to correct a blur of the capturing image.
