Abstract: PURPOSE:To accurately reproduce the image of roentgenoscopy because a roentgenoparent image is effectively stored and kept with a roentgenographic image by recording and displaying the roentgenoparent image with the roentgenographic image. CONSTITUTION:Usually, the roentgenoparent image is used for monitoring and continuously recorded in a digital VTR 10. At the time of generating the roentgenographic image, said image is recorded in the VTR 10 instead of the roentgenoparent image in the same system as a moving picture after performing buffering and dividing into blocks by an input image buffer 8 in order to adjust the roentgenographic image to the recording system of the VTR 10. At such a time, an identification code is added with a retrieval ID.

IPC: H04N7/24
Filed: 1979-03-12
Abstract: PURPOSE:To compress data efficiency by inserting a function discrimination code right before a code indicating unit area at a random point of a pattern. CONSTITUTION:When a function discrimination code is inserted from conductor 11 and coded input data is supplied to decoder 12, the function discrimination code for the screen start is detected in original data by an all-bit-''0'' unit area. Then, when oscillator 14 is turned ON via conductor 13 and the function discrimination code for the screen end is detected afterward, oscillator 14 is turned OFF via conductor 15. On the other hand, an original pattern decoded by decoder 12 and the output of oscillator 14 are OR-ed by OR gate 18 and print with screen effect is possible. Therefore, a pattern inferior in data compressibility such as a screen can be data-compressed with efficiency by only two function discrimination codes for the screen start and screen end.
