When a blurring process is performed for an image, noise is reduced according to the characteristics of a blurring process filter in a target region of the blurring process. Accordingly, a difference occurs in noise amount with a non-target region of the blurring process. In view of such situations, an image processing apparatus according to an embodiment of the present invention adds noise to the blurring target region. Accordingly, the difference in noise amount can be reduced, and a blurring-emphasized image with a natural texture can be created. Furthermore, the image processing apparatus according to the embodiment of the present invention determines the noise amount according to the blurring amount by the blurring process filter while considering that, the larger the blurring amount is, the more greatly the noise is reduced by the blurring process, and adds the noise. |

1. An image processing apparatus, comprising:
a reference image acquisition device which acquires a reference image of a subject; a blurring amount setting device which sets a blurring amount for the reference image; a blurred image creating device which applies a blurring process filter to the acquired reference image by the set blurring amount to generate a blurred image, the blurred image being created whose noise is reduced depending on characteristics of the blurring process filter; a difference calculation device which calculates a difference value between the acquired reference image and the generated blurred image, for the acquired reference image; and a combined image generation device which weights and adds the reference image and the blurred image, according to the calculated difference value, to generate a combined image. |
