By changing the quality of a display image, according to (a) the generation amount of the acoustic line data per unit time or (b) the number of display frames of an image, a resource control including the selection of the optimum drawing process algorithm is realized. Specifically, the two-dimensional drawing module (25) (i) periodically reads acoustic line data (S401), (ii) checks a scanning method of a physical structure of a probe and acoustic line data, and (iii) selects the optimum coordinate conversion algorithm (S402). After that, the two-dimensional drawing module (25) (i) selects an interpolation algorithm, based on a display rate (S403), (ii) generates display data by performing a two-dimensional DSC process using the selected coordinate conversion algorithm and the like (S404a, 404b or 404c), (iii) performs a persistence process for the display data (S405), a frame interpolating process for a "B mode" image data (S406) and a display color conversion process (S407), and (iv) transmits the display data after such processes as described above to the display unit (14) (S408). <IMAGE> |
