Image processing apparatus and image processing method

An image processing method comprising:

• acquiring a plurality of image data captured using different exposures;
• selecting an image data on which flicker noise detection is to be performed among the plurality of image data;
• applying flicker noise detection processing to image data selected in the selecting;
• computing, if flicker noise is detected in the detecting, a correction value for suppressing the flicker noise;
• and
• applying the correction value to image data of the same type as the image data selected in the selecting,
• wherein in the selecting, image data being captured with a shutter speed not having a predetermined value is selected from among the plurality of image data.

A non-transitory computer-readable medium storing a program for causing a computer to function as an image processing apparatus, comprising:

• an acquisition unit configured to acquire a plurality of image data captured using different exposures;
• a selection unit configured to select an image data on which flicker noise detection is to be performed among the plurality of image data;
• a detection unit configured to apply flicker noise detection processing to the image data selected by the selection unit;
• a computation unit configured to, if flicker noise is detected by the detection unit, compute a correction value for suppressing the flicker noise;
• and
• a correction unit configured to apply the correction value to image data of the same type as the image data selected by the selection unit,
• wherein the selection unit selects image data being captured with a shutter speed not having a predetermined value, from among the plurality of image data.
