DISPLAY METHOD FOR ULTRASONIC DIAGNOSING PICTURE

PURPOSE:To easily observe an ultrasonic diagnosing picture and to improve the ease of diagnosis by providing a look-up table in each diagnosing picture on a display picture and correcting each diagnosing picture with referring the correspondent look-up table. CONSTITUTION:The look-up tables to modes 1, 2 and 3 exist in memories 11, 12 and 13. When the data of the modes 1, 2 and 3 are assumed to be 256 gradations, the memories 11, 12 and 13 respectively have 0-255 addresses and luminance data are stored to the respective addresses. The data of the mode 1 are inputted to the address terminal of the memory 11 and correspondent data are read from the memory 11. The data of the mode 2 are inputted to the address terminal of the memory 12 and correspondent data are read from the memory 12. Then, the data of the mode 3 are inputted to the address terminal of the memory 13 and correspondent data are read from the memory 13. The data to be read from the memories 11, 12 and 13 are sent through an adder circuit 20 to a display part.
