Title: Reproducing device
Inventor: SAKAKIBARA MANABU
IPC: H04N5/93
Filed: 1988-07-08
Abstract: PURPOSE:To perform demodulation and reproduction with superior S/Ns by providing an equalizer circuit for video signals with different frequency bands and an equalizer circuit for audio, and using the equalizer circuit corresponding to a signal based on whether it is a High-Band video signal, a Low-Band video signal, or an audio signal. CONSTITUTION:H/L discrimination is performed by comparing the level of the carrier frequency band of Low-Band with that of High-Band by a comparator 54. A system controller 20 switches the equalizer circuit to an H.B-EQ7, an L.-EQ8, or an A-EQ9 by a change-over switch 13 corresponding to whether the signal is the High-Band video signal, the Low-Band video signal, or the audio signal. Thus, since the optimum compensation of the output of a reproducing head can be performed by providing plural equalizer circuits for each signal and selecting the equalizer circuit corresponding to the signal to be reproduced, it is possible to improve the S/N by the reduction of reversal and the improvement of a C/N.

IPC: H04N5/765
Filed: 1991-06-13
Abstract: PURPOSE:To prepare an electronic still camera easy to operate by switching the operating mode to the recording mode by means of release switch operation. CONSTITUTION:Mode controller 41 discriminates whether the still camera is executing regeneration or not, and if the regeneration is on, the mode controller 41 displays various types of information on a display section 43. Then, the mode controller 41 stops the regenerating action, executes release processing, takes picture of field, and stores the picture in a vacant track on a magnetic disk. If the still camera is not executing regeneration (non-regeneration), the mode controller 41 checks whether or not a release switch 31 is pressed. Then, if the release switch 31 is pressed, the controller 41 executes release processing, and terminates the re-mode interrupt processing. According to this constitution, the electronic still camera 10, even when recorded image from the magnetic disk is under regeneration, only by pressing the release switch 31 the operation mode can be switched to the recording mode. Without taking a troublesome operation, the still camera can start to take picture.

Title: Video tape recorder
Inventor: NOCHIDA KAORU
IPC: G11B5/027
Filed: 1990-06-26
Abstract: PURPOSE:To prevent the distortion of a reproduced picture at the time of a high-speed search by outputting a prescribed correction signal instead of a reproduced video signal until a synchronizing signal is successively reproduced after the signal level of a regenerative signal falls to less than a prescribed value. CONSTITUTION:A regenerative signal SRF is applied to a drop-out detecting circuit 6. At that time, when the signal level of the signal SRF falls to less than the prescribed value, a drop-out detecting signal DO is prepared. The detecting signal DO as mentioned above and a guard-band processing signal SCON are outputted through a selecting circuit 1 3 to a time base correcting circuit 15. Thus, a video signal SV is grey-muted based on the signal DO when the signal SV is operated for the high-speed search at less than +30 time speed. On the other hand, the signal SV is grey-muted based on the-signal SCON when the signal S is operated for the high-speed search at more than +30 time speed. Thus, a display picture in which there is not any distortion can be obtained at the time of high-speed search.
