Title: Synchronizing signal sampling circuit
Inventor: NARITA ATSUO
IPC: H04N5/08
Filed: 1986-12-22
Abstract: PURPOSE:To sample a synchronizing signal with high accuracy even from a video signal of adverse quality by applying pulse clamp except the 9-line vertical period where distortion is often caused easily thereby correcting leakage current caused during the 9-line vertical period. CONSTITUTION:A high frequency component is eliminated from an input video signal at first by an LPF, the result is fed to an amplifier 1, where the level is amplified and a built-in limiter eliminates the signal of the picture part above the slice level. A DC bias control circuit 2 to ensure the operation of the amplifier 1 is provided. The pedestal part in the output of the amplifier 1 is fixed in terms of DC to ensure the elimination of the signal of the picture part. The pedestal part of the output of the amplifier 1 is clamped to a ground level by using a clamp FETQ2. In such a case, since the synchronizing signal itself is often distorted during the 9-line vertical period, a leakage current correcting circuit 3 is provided to inhibit the DC bias control and clamping operation and to suppress the fluctuation of the DC level during this period.

Title: Recording method for still picture recording/reproducing device
Inventor: SATO YOSHIAKI
IPC: G11B27/029
Filed: 1990-11-14
Abstract: PURPOSE:To prevent the occurrence of inconvenience in a sound signal, which occurs at the time of video release by recording the sound signal collected before video release in correspondence with the video signal. CONSTITUTION:When a sound collection switch 52 is turned on and the desired sound signal is collected, the sound signal is stored in RAM 45 in the same way as the case of a normal mode. When a video release switch 36 is turned on and the video signal is stored, the video signal is recorded in the prescribed track of a magnetic disk 12 in the same way as the case of the normal mode. When the recording completes, a magnetic head 15 immediately moves to an inner track by one and the collected sound signal is recorded here. Thus, it can previously be prevented that noise occurring at the time of video release is mixed in the recorded sound signal and the occurrence of inconvenience on the sound signal such as the distortion of the sound signal accompanied by the deterioration of the voltage can previously be prevented.

IPC: A61B10/00
Filed: 1987-12-02
Abstract: PURPOSE:To process images in a short time after the change of a parameter by using either of stored raw image data or a processed intermediate result. CONSTITUTION:A memory means 1 stores the raw image data received from an external device 10 and a memory means 2 stores the intermediate processing result of the raw image data to be processed by a data processing means 9. Then information filtered by an N parameter is stored in the means 2. In case a beta parameter is newly changed, an image is obtained by applying a frequency emphasizing process to the raw image data of the means 1 via a frequency emphasizing part 6. Then the image processing is possible with no filtering process when the data of the means 2 is used to perform the frequency emphasizing process. Thus the image processing time can be shortened.

Title: Metastable state detection device
IPC: H03K3/037
Filed: 1992-10-21
Abstract: PURPOSE:To obtain a device which can detect the metastable state of a trigger effectively using a simple circuit configuration. CONSTITUTION:A microprocessor 14 determines a specified address value of an address generator 26 for determining a timing for accepting a trigger event. A trigger ready comparator 28 detects that the address of the address generator 26 reached the specified address value, thus generating a trigger ready signal. The trigger ready signal enables a trigger event signal to be generated. The current address value of an address generator 20 at the point when the trigger event is generated is stored in the trigger address latch 20. The difference between the current address value and a specified address value which is supplied to the trigger ready comparator 26 is obtained and then it is judged that there is a possibility that a metastable state may occur if the difference is within a specified range, thus eliminating the need for an additional hardware and detecting the metastable state.
