Abstract
Abstract An ultrasonic image output apparatus has a frame memory for storing image data for each frame of ultrasonic images. The image data stored in the frame memory is read out in a time-division manner to be transferred to a display and a scanning/recording device to be displayed and recorded. For the time-divisional data transfer to the display, data is read out from the frame memory by, for example, scanning in accordance with the standard television format. Data is read out and transferred to the scanning/recording device during a blanking period of the scanning operation by the standard television format. The time-divisional data read operation is controlled by a timing circuit synchronously with display scanning of the display.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
144 words
An ultrasonic image output apparatus comprising: generating means for generating a frame of ultrasonic image data; memory means connected to said generating means for storing the ultrasonic image data at pixel storage locations which are arranged in columns and rows; display means connected to said memory means for reading the ultrasonic image data from said memory means by accessing said pixel storage locations, and displaying the ultrasonic image represented by said data in a television format; and line scan recording means connected to said memory means for reading the ultrasonic image data from said memory means by accessing at least one of the pixel storage locations of a line in column direction or row direction during each blanking period of said television format, and recording the line of the ultrasonic image formed of the pixels corresponding to the storaged locations which have been accessed.
Claim 2
Dependent Claim
144 words
An ultrasonic image output apparatus comprising: generating means for generating a frame of ultrasonic image data; memory means connected to said generating means for storing the ultrasonic image data at pixel storage locations which are arranged in columns and rows; display means connected to said memory means for reading the ultrasonic image data from said memory means by accessing said pixel storage locations, and displaying the ultrasonic image represented by said data in a television format; and line scan recording means connected to said memory means for reading the ultrasonic image data from said memory means by accessing at least one of the pixel storage locations of a line in column direction or row direction during each blanking period of said television format, and recording the line of the ultrasonic image formed of the pixels corresponding to the storaged locations which have been accessed.
Claim 3
Dependent Claim
42 words
