Abstract:
1. An image processing method comprising: obtaining an input image generated by an image pickup system; generating a first image through restoration processing of an amplitude component and a phase component of the input image, the restoration processing being performed to reduce an amplitude degradation component and a phase degradation component, which are generated by degradation of the amplitude and phase components due to aberration of the image pickup system, by using an image restoration filter generated based on an optical transfer function of the image pickup system, the phase degradation component being an asymmetric image component corresponding to an asymmetric point spread function of the image pickup system, the reduction of the phase degradation component increasing symmetry of the phase degradation component, and the restoration processing being performed by convolution of the image restoration filter on the input image; generating a second image that has an equal state of the phase component to that of the first image and a different state of the amplitude component from that of the first image through the restoration processing of the phase component without the restoration processing of the amplitude component of the input image; obtaining difference information between the first image and the second image; setting a restoration level adjustment factor to be used to adjust a restoration degree in the restoration processing; and generating a restoration adjusted image by composing the difference information with the second image according to the restoration level adjustment factor.
