Provided are an apparatus and method that obtain a numerical value for an evaluation value of an appearance of noise in a plurality of videos and that coordinate the appearance of noise based on the evaluation value. In an image processing apparatus that coordinates an appearance of noise among a plurality of videos, noise properties are obtained from the videos, and a noise evaluation value is calculated based on the noise properties. Based on the calculated noise evaluation value, noise to be added to the videos is calculated, and the added noise is then added to the videos.
