Image processing apparatus, image processing method, and program

摘要

Provided is an image processing apparatus that reduces over recovery of image data by image recovery processing. An image processing unit selects an image recovery filter corresponding to an imaging condition and performs image recovery processing on captured image data using the image recovery filter. Further, the image processing unit limits a change amount of a pixel signal value of the image data by the image recovery processing based on a change amount limit value determined according to characteristics of a gamma correction processing that is applied after the image recovery processing.

1. An image processing apparatus comprising:
an image recovery processing unit configured to perform image recovery processing, on image data captured by an imaging unit, using an image recovery filter corresponding to an imaging condition in the imaging unit; and a limiting unit configured to, in a case where a difference between a post-image-recovery-processing signal value and a pre-image-recovery-processing signal value is greater than a limit value determined according to characteristics of a gamma correction processing that is applied after the image recovery processing, output a corrected signal value so that a difference between the corrected signal value and the pre-image-recovery-processing signal value is equal to or less than the limit value.
