Image processing apparatus and image processing method

An image processing method, comprising:

• a step to acquire a plurality of tomographic luminance images obtained by photographing an object at different times, and a plurality of polarization-sensitive tomographic images corresponding to the plurality of tomographic luminance images;
• a step to position the acquired plurality of polarization-sensitive tomographic images, by at least deforming at least one of the acquired plurality of polarization-sensitive tomographic images so that correlation of the acquired plurality of tomographic luminance images is greater than a threshold value;
• and
• a step to generate a new polarization-sensitive tomographic image, using the plurality of polarization-sensitive tomographic images which are positioned.

A non-transitory computer-readable storage medium storing a program for causing a computer to execute an image processing method, the image processing method comprising:

• a step to acquire a plurality of tomographic luminance images obtained by photographing an object at different times, and a plurality of polarization-sensitive tomographic images corresponding to the plurality of tomographic luminance images;
• a step to position the acquired plurality of polarization-sensitive tomographic images, by at least deforming at least one of the acquired plurality of polarization-sensitive tomographic images so that correlation of the acquired plurality of tomographic luminance images is greater than a threshold value;
• and
• a step to generate a new polarization-sensitive tomographic image, using the plurality of polarization-sensitive tomographic images which are positioned.

An image processing apparatus, comprising:
