Document Type and Number:
Japanese Patent JP5554453
Kind Code:
B2
Abstract:
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.
