1. An image processing apparatus comprising: one or more processors configured to: correct a geometric mismatch of optical noise of a left eye image and a right eye image, wherein the geometric mismatch of a first striation and a first light ray occurring in the left eye image and a second striation and a second light ray occurring in the right eye image is corrected, the correction of the geometric mismatch comprising: performing a noise removal process remove separately generated optical noise on the left eye image and the right eye image, wherein the left eye image and the right eye image are captured by a two-lens type stereoscopic image capturing camera; detect a striation region comprising a light source, a striation and a light ray, and a striation background region adjacent to the detected striation region from each of the left eye image and the right eye image; and replace the striation region and the striation background region of one of the left eye image and the right eye image with the striation region and the striation background region of other of the left eye image and the right eye image.
