摘要： An apparatus for reproducing from a recording medium a frequency-modulated audio signal which has its carrier level in a specific period determined according to the kind of information and for producing the audio signal after processing the reproduced audio signal is arranged to control the signal processing action according to the output of a detecting circuit which detects the level of a difference between the carrier level of the frequency-modulated audio signal obtained in the specific period and the carrier level obtained in a period other than the specific period or detects changes taking place in the carrier level. This arrangement enables the apparatus to process the audio signal appositely to the kind of the frequency-modulated signal thereof without recourse to any additional reproducing circuit solely for this purpose. Further, the apparatus is arranged to prevent any faulty signal processing action by nullifying as necessary the output of the detecting circuit.

摘要： In an image signal recording system for recording on a recording medium an original image signal corresponding to an original picture which is comprised of a plurality of pixels, the original picture is divided into a plurality of pixel blocks each consisting of a predetermined number of pixels, and image signals each corresponding to the associated pixel block divided are recorded on the recording medium in accordance with a first recording mode and a second recording mode which are mutually different in a recording format. Either of the first and second recording modes is selected on each of the plurality of pixel blocks and a recording mode information signal corresponding to the selected recording mode is generated. There are recorded on the recording medium, the first image information signal or the second image information signal formed and the recording mode information signal generated, on a multiple basis. Thus, it is possible to provide the image signal recording system capable of efficiently recording image signals while suppressing a deterioration of the image quality.

摘要： A photographic optical system and a viewfinder are disposed above a recorder casing for recording a signal obtained by photography. The photographic optical system and the viewfinder are disposed so as not to overlap each other in a direction parallel to an optical axis of the photographic optical system and so that an optical path of the photographic optical system and an optical path of the viewfinder overlap each other as viewed on an extended line of the optical axis of the photographic optical system. In addition, the photographic optical system is disposed above the recorder casing, and the recorder casing is arranged to eject downward a recording medium for recording of a signal obtained by photography. A grip is disposed on one side of the aforesaid recorder casing, and an operating part for driving a mechanism for varying the magnification of the photographic optical system is provided at the rear of the photographic optical system.
