9. An image processing method for an image processing apparatus comprising a probe with an illumination fiber and a detection fiber, and a controller with at least one memory and at least one processor, the illumination fiber being configured for optical communication with a light source, the image processing method comprising:
causing the controller to execute instructions to implement steps comprising:
receiving an input image based on image data;
executing noise reduction processing on the image data by using view angle and rotation angle data of the probe to calculate a value using reference pixels based on a first frequency range, and subtract a second value using pixels based on a second frequency range; and
output noise-reduced image data based on a result of the noise reduction processing,
wherein ghost noise is reduced in the image reconstruction process.
