Image processing method, image processing apparatus, image pickup apparatus, and storage medium storing image processing program

摘要

The image processing method includes acquiring an input image produced by an image pickup system including at least one imaging optical system and causing light rays from a same point in an object space to respectively enter different image pickup pixels depending on light ray passing areas of a pupil through which the respective light rays pass, performing a shaping process including at least one of an image restoration process to restore a degraded image and a luminance estimation process to estimate a luminance of a saturated area, a reconstruction process to reconstruct a new image different from the input image, and performing a blur addition process to add an image blur component to an addition target image. The method performs the shaping process before the reconstruction process and the blur addition process.

1. An image processing method comprising:
acquiring an input image produced by an image pickup system including at least one imaging optical system and causing light rays from a same point in an object space to respectively enter different image pickup pixels depending on, of a pupil plane of the at least one imaging optical system, light ray passing areas through which the respective light rays pass; performing a shaping process including at least one of an image restoration process to restore a restoration target image on a basis of an optical transfer function of the image pickup system and a luminance estimation process to estimate a luminance value in a luminance saturated area in an estimation target image; performing a reconstruction process to reconstruct a new image different from the input image; and performing a blur addition process to add an image blur component to an addition target image, wherein the method performs the shaping process before the reconstruction process and the blur addition process.
