1. An electronic apparatus comprising: circuitry configured to: calculate a weighted average image from a first image, a second image and a third image, by using a weight based on a first difference between the first image and the second image and a second difference between the first image and the third image; and apply, based on the weight, an image quality process of a first intensity to a first position in the weighted average image, apply, based on the weight, an image quality process of a second intensity to a second position in the weighted average image, the second intensity weaker than the first intensity, and apply, based on the weight, an image quality process of a third intensity to a third position in the weighted average image, the third intensity weaker than the second intensity.
