Abstract

PURPOSE: To miniaturize a system and to attain easy moving by executing subtraction concerning two pieces of picture data, inputted to an arithmetic circuit, with the control of a control circuit.
CONSTITUTION: A frame memory 6, an arithmetic circuit 8 and a control circuit 7 are integrated into the internal part of a digital VTR 1 and identifying information are recorded to a recording medium such as a magnetic tape, etc., together with the picture data in order to identify which kind of pictures the picture data are. At the time of reproducing, the two pieces of the suitable picture data are recorded and held to the frame memory 6 according to the identifying information and transferred to the arithmetic circuit 8. Then, the subtraction is executed and the data can be outputted. Thus, the picture processing unit in the picture in a digital subtraction angiography DSA device is eliminated. Then, the system can be miniaturized and the moving can be easily executed.
