Classification: CPC G | IPC G

Claim 7:
8. An image processing method for generating a correction image in which brightness of a captured image acquired by capturing an object is changed, the image processing method comprising:
acquiring the captured image;
specifying a region including in at least part of the object in the captured image; and
generating the correction image in which brightness of at least part of the specified region in the captured image is changed using pixel values of pixels in the captured image,
wherein generating the correction image comprises generating the correction image so that a first region of the specified region in the correction image has stronger shade than a second region of the specified region in the correction image, the first region being different from the second region,
wherein a degree of change of brightness of a first pixel from the captured image to the correction image is different from a degree of change of brightness of a second pixel from the captured image to the correction image,
wherein the first pixel and the second pixel are included in the specified region, and
wherein a distance from an imaging device at the first pixel is equal to a distance from the imaging device at the second pixel, and a normal direction corresponding to the first pixel is different from a normal direction corresponding to the second pixel.
