えることを特徴とする静止画再生装置。[Claims for Utility Model Registration] An in-line thin film head having two playback heads for respectively playing back video signals of different fields recorded on adjacent tracks of a magnetic disk, and demodulating the playback output of each of the playback heads. first and second demodulation circuits that delay and output the output of each demodulation circuit by 0.5H (H is a horizontal scanning period); and a mode designation signal that designates the playback mode. Based on this, in the field regeneration mode, the output of the first demodulation circuit and the first
The output of the delay circuit is alternately switched and outputted for each field, and the output of the second demodulation circuit and the second delay circuit is alternately switched and outputted for each field. A still image reproducing apparatus characterized by comprising: switching means for alternately switching and outputting the output of each of the demodulation circuits for each field in response.
