Abstract
There is provided an image processing apparatus. An estimation unit estimates a color difference component of noise included in a captured image that has undergone white balance correction. A determination unit determines a strength of color suppression processing based on a size of the color difference component of the noise. A processing unit applies the color suppression processing to the captured image at the determined strength.
Claims11
An image processing apparatus comprising:
- at least one processor;
- a memory coupled to the at least one processor storing instructions that, when executed by the at least one processor, cause the at least one processor to function as:
- an estimation unit configured to estimate a color difference component of noise included in a captured image that has undergone white balance correction, based on a white balance gain determined for each color;
- a determination unit configured to determine a strength of color suppression processing based on a size of the color difference component of the noise;
- and
- a processing unit configured to apply the color suppression processing to the captured image at the determined strength.
An image processing method executed by an image processing apparatus, comprising:
- estimating a color difference component of noise included in a captured image that has undergone white balance correction based on a white balance gain determined for each color;
- determining a strength of color suppression processing based on a size of the color difference component of the noise;
- and
- applying the color suppression processing to the captured image at the determined strength.
A non-transitory computer-readable storage medium which stores a program for causing a computer to execute an image processing method comprising:
- estimating a color difference component of noise included in a captured image that has undergone white balance correction based on a white balance gain determined for each color;
- determining a strength of color suppression processing based on a size of the color difference component of the noise;
- and
- applying the color suppression processing to the captured image at the determined strength.
