<p>PURPOSE:To reduce the total amount of hardware by writing and reading alternately two frame memories which are stored with information as much as one picture in a display television screen. CONSTITUTION:The frame memories 1 and 2 connecting with input data 10 from an ultrasonic diagnostic device (not shown in a figure) are connected to a display television (unshown), and the memories 1 and 2 are connected to a write address generating circuit 3 and a read address generating circuit 4 respectively. In this case, image information from the ultrasonic diagnostic device is written in, for example, the memory 2 with a write address signal 30 generated by the circuit 3 repeatedly until one picture is constituted, and the memory 1, on the other hand, is read with a read address signal generated by the circuit 4. The memories 1 and 2 are replaced with each other after one picture is constituted. Thus, line buffer memory etc., are reduced greatly.</p> |
