Abstract

PURPOSE:To attain inexpensive long time video recording by recording a still picture signal stored tentatively in a storage circuit on an audio tape recorder for a prescribed time, repeating the said operation intermittently and reproducing plural still pictures continuously. CONSTITUTION:A video signal from a CCD element 1 is stored tentatively in a storage circuit 4 via an amplifier 2 and an analog/digital converter 3 in the setting of the video recording mode. Then the signal is again converted into an analog signal by a digital/analog converter 5 and recorded on a tape via a head drive circuit 6 and a fixed head 7. Then a still picture signal reproduced by the fixed head 7 from the tape in the setting of the reproduction mode is displayed on a display device 10 from the digital/analog converter 9 via a reproducing amplifier 8. Moreover, the video recording is able to be repeated and after one still picture signal is recorded for a prescribed time, the succeeding still picture signal is recorded.
