Abstract

PURPOSE:To convert the data from an ultrasonic reflected wave to image data at a high speed, by providing a weighting circuit for performing predetermined weighting to the digital data read from a memory means and an image data forming means for successively converting the weighted data to the image data. CONSTITUTION:A data output means 1 outputs the digital data obtained from an ultrasonic reflected wave. The digital data obtained from the ultrasonic reflected wave is written in a memory means 2 composed of the addresses of a 2Xn system and constituted of (n<2>) memory banks. Therefore, digital data necessary for performing predetermined weighting can be simultaneously read on the basis of the addresses of the 2Xn system and the digital data subjected to predetermined weighting by weighting circuits 31-3m (m=n<2>) are obtained at a high speed and successively receive processing such as addition by an image data forming means 4 to be converted to image data for display and said image data is displayed on a display means 5.
