In tracing a tape with a signal recording head to form tracks having digital data recorded thereon, a plurality of tracks provide each of blocks, and a usual playback data area NA and trick playback areas TH and TL are arranged on each of the tracks included in each block. The trick playback areas are enlarged to provide increment areas TA with a decrease in the bit rate of usual playback data. In recording image data as to a plurality of programs on a tape conjointly, signal recording tracks are formed on the tape, and a usual playback data area and a trick playback data area are formed on each of the tracks or on one track per plurality of tracks, as arranged longitudinally of the track, whereby the image data as to programs A to D is conjointly recorded on the same tape. In this method, a number of tracks in accordance with the number of speed multiplication for trick playback provide one TP frame, the same trick playback data is repeatedly recorded from track to track in the trick playback data areas of the tracks within the same TP frame, and the image data as to the programs A to D is cyclically recorded in such respective TP frames, each for one program.

Method of recording image data

In the event of recording a picture signal for left eye and a picture signal for right eye, a picture signal for one of right and left eyes limited in band by a low pass filter as being an additional signal and a picture signal for the other eye as being a primary signal, and the additional signal together with the primary signal are recorded on recording medium.

Method for recording at least two picture signals and method of

In processing a video signal reproduced from a track of a magnetic disc (10), if the reproduction video signal, from one track of the frame recorded on two adjacent tracks, is stored in a memory (34), then the control circuit (20) determines whether the memory (34) should be used as a field memory or a frame memory based on a field/frame discriminating signal reproduced from the reproduced track. Therefore, error which occurs when only one of the two tracks is erased, can be prevented.

Still picture processing apparatus for a still camera

A beam-indexing color picture tube includes a gun for producing an electron beam that scans across a screen of the tube and a plurality of index phosphor stripes provided on the screen for emitting near-ultraviolet index lights. The near-ultraviolet index lights are transmitted through a window formed in the tube to a detector. The detector is formed by a planar fluorescent collector doped with fluorescent material for absorbing the near-ultraviolet index lights, and at the same time, generating secondary index lights having different wavelength than that of the near-ultraviolet index lights. A silicon p-i-n photodiode is mounted on the planar fluorescent collector for detecting the secondary index lights and for generating electrical signal representing the near-ultraviolet index lights.
