PURPOSE:To equally record by either one of a skip scanning system or a sequential scanning system by storing an output signal from a TV camera in a picture memory as a digital by an A/D converter and carrying out the reading and the writing of a picture memory by respectively individually shifting the phase of an address. CONSTITUTION:When the output signal of the TV camera of the sequential scanning system is recorded on a video tape recorder, the writing to the picture memory is successively carried out to the scanning. The reading of data is attained by reading an odd number line and then reading an even number line. The output signal of the X ray TV camera 1 is converted into the digital signal in the A/D converting part 2, passed through a selection circuit 3, guided to an arithmetic control circuit 4 and stored in the picture memory 5. The output of the picture memory 5 is guided to a data converting part 8, converted into a signal for recording, thereafter, supplied to the video tape recorder 9. A reproduced signal from the video tape recorder 9 is converted into an original picture by the data converting part 8, passed through the selection circuit 3 and guided to the arithmetic control circuit 4. |
