PROBLEM TO BE SOLVED: To improve display quality of each image with different display contents on a display device having a fixed display frequency. SOLUTION: An ultrasonic photographing portion 1 and a personal computer 2 are interconnected and constituted through a bus line 3, a CPU 6 and a graphics controller 11 simultaneously display and control respective images in an M-mode and a B-mode formed by an image reconstituting portion 5 onto respective display regions of a monitor device 12. The CPU 6 and the graphics controller 11 update and display the image in the M-mode every one field (60 Hz), and update and display the image in the B-mode every one frame (30 Hz). Since this allows display and control according to display contents of each image, even on a display device having a fixed display frequency, an image with high display quality can be displayed. |
