摘要：

PROBLEM TO BE SOLVED: To provide an image processing apparatus and an ultrasonic diagnostic apparatus generating a naturally-looking image.

SOLUTION: An original image is acquired by ultrasonic scanning of a subject and an interpolation pixel is determined on the original image. Four original pixels near the interpolation pixel is then selected and different random components rand(1+j+f+d)%Sw-Sw/2, rand(2+j+f+d)%Sw-Sw/2, rand(3+j+f+d)%Sw-Sw/2 and rand(4+j+f+d)%Sw-Sw/2 are added respectively to pixel values p1, p2, p3 and p4 of the four original pixels to acquire random processed original pixel values. After that, the four random processed original pixel values are subjected to weighted addition and an acquired pixel value is designated as a pixel value Rk of the interpolation pixel. As a result, the degree of freedom of added random components becomes 4, so that a natural-looking degree is improved.
