PURPOSE:To eliminate the lapse of time in an image and to exactly display an image of a quick motion such as the heart, etc., by displaying an image obtained by bringing some line image data of the present frame, and the same line image data of the frame being preceding to an averaged same time phase. CONSTITUTION:By an arithmetic part 2, etc., some line image data of the present frame, and the same line image data of the frame being preceding by one which read out of an auxiliary memory 1 are brought to an averaged same time phase. By the line image data brought to the time phase averaged, an image is displayed. In this case, the image data of the present frame is written in the auxiliary memory 1, and used at the time of the averaged same time phase averaging the next time. Accordingly, by displaying the image obtained by bringing some line image data of the present frame, and the line image data of the frame being preceding to the averaged same time phase and by the adding, a lapse of time in an image in one screen is eliminated, and an image of a quick motion such as the motion of heart, etc., can be exactly displayed. |
