<P>PROBLEM TO BE SOLVED: To improve image quality of an ultrasonic image by enhancing the density thereof. <P>SOLUTION: In a frame 202, a first pixel array 204, a second pixel array 206, and a third pixel array 208 are defined. For each pixel of interest on the first pixel array 204, a pattern matching process is applied between the first pixel array 204 and the second pixel array 206, to calculate the mapping address on the second pixel array 206 for the pixel of interest. In addition, for each pixel of interest on the third pixel array 208, a pattern matching process is applied between the third pixel array 208 and the second pixel array 206, to calculate the mapping address on the second pixel array 206 for each pixel of interest. The second pixel array 206 is re-constructed into a high-density pixel array using pixel values and mapping addresses of a plurality of pixels of interest. A re-constructed frame is formed by a plurality of high-density pixel arrays. <P>COPYRIGHT: (C)2012,JPO&INPIT |
