摘要： PROBLEM TO BE SOLVED: To control an amplifier, obtaining constant output amplitude according to the amplifier of an input signal by detecting and smoothing the output signal of a voltage control amplification circuit and feeding back the gain control signal of an amplification circuit. SOLUTION: The amplitude of the input signal is detected in a level detection circuit 106 from the output of a voltage control amplification circuit 105 and is smoothed. Then, it is supplied to the control terminal (a) of the circuit 105. Thus, the gain of the circuit 105 is controlled according to the amplitude of the input signal and it is amplified, so that the amplitude of the output signal becomes almost uniform. When the amplitude of the input signal is large. For example, the amplitude of the output sound signal of the circuit 105 becomes large. Thus, the circuit 106 detects it and controls a control signal level supplied to the terminal (a) of the circuit 105, so that the gain becomes small and the gain of the circuit 105 is reduced. Thus, the amplitude of the output sound signal is reduced, and the output sound signal is made uniform. Therefore, a circuit operates as an amplitude restriction circuit.

摘要： PROBLEM TO BE SOLVED: To display an image with a same field angle as that of an image caught by a still zoom lens and a video zoom lens on a liquid crystal display panel. SOLUTION: A finder image caught by an electronic view finder section 21 is displayed on a liquid crystal display panel 12 and a zoom lens 21a of the electronic view finder section 21 is driven so as to have a zoom magnification of a video zoom lens 22 in the case of video image pickup and driven so as to have a zoom magnification of a still zoom lens 11 in the case of still image pickup. In the case that the video and still image pickup are both conducted simultaneously, the zoom lens 21a of the electronic view finder section 21 is driven so as to have a zoom magnification of the video zoom lens 22 or the still zoom lens in the wide angle mode. A wide angle image is displayed on the liquid crystal display panel 12 and the image at the telescopic position is displayed as a slave image pattern.

摘要： PURPOSE: To highly faithful extraction of synchronization signals containing jitters by improving the S/N of synchronization signal components. CONSTITUTION: Frequency demodulating means 60-64 demodulate the frequency components corresponding to the synchronization signal components of frequency-modulated luminance signals reproduced from a recording medium. An amplifying means 65 amplifies the luminance signals obtained by means of the modulating means 60-64, so that the sink chip level of the luminance signals may become a prescribed level by changing its gain. A clamping means 66 clamps the luminance signals outputted from the amplifying means 65, so that the pedestal level of the signals becomes a prescribed level. An extracting means 67 extracts synchronization signals by comparing the synchronization signal of the luminance signals outputted form the clamping means 66, with a level roughly set at the middle of the sink chip level of the amplifying means 65 and the pedestal level of the clamping means 66.

摘要： PURPOSE: To provide a chrominance component modulation circuit which can reduce the vertical roughness of the monitor picture of videos from a camera at recording and, in addition, the vertical spread of colors in the picture at reproducing. CONSTITUTION: A first modulator 43 modulates line sequential chrominance components and a first delay circuit 46 delays the modulated chrominance components outputted from the modulator 43 by one horizontal scanning period. A first mixer 45 generates interpolation type sequential simultaneous modulated chrominance components for recording on a magnetic tape by mixing the modulated chrominance components outputted from the modulator 43 with the modulated chrominance components delayed at the delay circuit 46. Comb line filters 46 and 47 generate average type sequential simultaneous modulated chrominance components for monitoring from the modulated chrominance components for recording outputted from the mixer 45.

A control circuit 23 generates and supplies the drive control signal in the capstan motor drive circuit 21 and the drum motor drive circuit 22, on the basis of the signal detected by the DET 6. Thus, the control circuit 23 controls the capstan motor drive circuit 21 and the drum motor drive circuit 22 and synchronizes the signal recorded on the magnetic tape 7 by a prescribed recording pattern.

摘要： PROBLEM TO BE SOLVED: To increase the quantity of information of the still camera without missing dynamic image information by recording the information of the still camera in the case of shutter release onto a magnetic tape as additional information. SOLUTION: When a shutter release button is depressed, a control section 24 allows a camera signal processing circuit 21 to write image data to a memory 22 and generates a control signal denoting a corresponding squelch number, shutter release information and date and time and a control signal denoting required information such as an aperture and a shutter speed and provides the control signals to a recording reproduction processing circuit 14. AUX information generated according to the control signals is recorded on a magnetic tape 18. Then an operation section 23 is used to enter a still number to indicate reproduction of a still image, then the signal processing circuit 21 reads the instructed image data from the memory 22 and gives the data to a character insert circuit 19 and also applies high speed search to the magnetic tape 18 so as to detect a recording track coincident with the still image and the AUX information is mixed with the image by the character insert circuit 19 and the mixed signal is displayed.

摘要： PROBLEM TO BE SOLVED: To prevent unpleasant noise at zoom lens drive from being recorded onto a magnetic tape by attenuating an audio signal in interlocking with the operation of the zoom lens controlling a field angle of an image formed onto a film. SOLUTION: A video camera section 3 reaches a recording state by an operation of a video camera operation section 6a. When the camera section 33 reaches the recording state, the attenuation of an audio control circuit 13a is maximized to record no audio signal onto a magnetic tape. The attenuation of the audio control circuit 13 is decreased in a prescribed time and the audio recording by the video camera section 3 restores to the normal state. In the case of the recording state of the video camera 3, when a zoom lens operation section 6c of an operation section 6 is operated, the attenuation of the audio control circuit 13a is maximized to record no audio signal onto the magnetic tape 2. Thus, unpleasant zoom lens operation noise is not recorded onto the magnetic tape 2. When a stop button of the operation section 6a is operated, the attenuation of the audio control circuit 13a is increased and the camera section 3 is stopped with the maximum attenuation.

摘要： PROBLEM TO BE SOLVED: To allow a field angle of a still camera to be confirmed on a liquid crystal display panel when a video camera is used for picking up an image of an object. SOLUTION: An image picked up by an electronic view finder section 21 or a video camera section 34 is displayed on a liquid crystal display panel 12. A zoom magnification of a zoom lens 21a of the electronic view finder section 21 is controlled in tracking with a zoom magnification of a zoom lens 22 of a still camera section 32 and in the case of still image pickup, an image picked up by the electronic view finder section 21 is displayed on the liquid crystal display panel 12 in matching with a video image caught by the still camera section 32. In the case of conducting both the video image pickup and the still image pickup simultaneously, either of the image picked up by the electronic view finder section 21 and the image picked up by the video camera section 34 is selected to be a master image and the other is to be a slave image and displayed on the liquid crystal display panel 12 depending on the operation of the screen changeover switch 34.
