摘要： PROBLEM TO BE SOLVED: To suppress the increase of the number of switch circuits through the use of a VTR switch provide in a lens and a VTR switch provided in a camera body connected to the lens as switches having other functions, when the camera is not connected to the lens. SOLUTION: A CPU 5 checks a connection identification signal 5d such as a VTR, operates a logical OR of a signal 3a of a VTR switch 3 of a lends 1 and a signal 4a of a VTR switch 4 of a camera body 2, when it is decided that a camera is connected to the VTR, etc., and calculates and from the result outputs a start/stop signal 5a of the VTR, etc., to a subsequent stage. Or when it is decided that the camera is not connected to the VTR, etc., the CPU 5 inputs the signal 3a of the switch 3 of the lens 1 and outputs a switch signal 5b of a send back video output to the subsequent stage. Also, the CPU 5 inputs the signal 4a of the switch 4 of the body 2 and controls to output a call signal 5c in response to it.

摘要： PURPOSE:To enable adjustment to the best upper edge only with a test signal and to improve efficiency for adjustment by adding control data for correcting characteristics from an optical system to a preamplifier to basic control data due to the test signal, and performing the adjustment. CONSTITUTION:A control data file 9 for correction stores difference between an adjusting value 10, which adjusts a process amplifier 6 with a test signal 7a generated by a test signal generator 7, and an adjusting value 11 adjusting an optical system 2 and a preamplifier 4 with an object. At the time of camera operation, these control data for correction are supplied to a control signal output circuit 8 and the operation is controlled. Thus, the optical system or preamplifier of the television camera apparatus can be adjusted to the best state only by adjusting it with the test signal.

摘要： PROBLEM TO BE SOLVED: To provide a television camera device which controls the iris of an image pickup lens by outputting an iris control signal corresponding to a luminance signal constituting a video signal and a hue signal from a CPU to make the luminance of hue that is designated in a designated area constant and makes the luminance of an object constant even when the background illuminance of a prescribed object is changed. SOLUTION: A television camera device which keeps the output level of a video signal almost constant by controlling an iris has an area designating circuit 14 which outputs a video signal of a designated area, a hue adapting circuit 16 which outputs a hue signal that is compared and operated and a hue designating circuit 15 which outputs a video signal of a designated area and a designated hue when the video signal of the designated area coincides with a signal which is acquired by comparing the hue signal that is compared and operated and designated hue data and keeps the output level of a video signal almost constant by controlling an iris by means of an iris control signal corresponding to the level changes of the designated area and designated hue.

摘要： PURPOSE:To facilitate the confirmation method of an operator, to save the labor of the operator and to eliminate errors by simultaneously displaying the adjustment states of plural cameras at a display device. CONSTITUTION:The camera control signals 1a, 1b... of the plural cameras are connected to a camera control switching circuit 1. The control signal 12 of the camera selected by a camera selecting signal 11 is connected to a camera control signal input/output circuit 2 and the control of the selected camera becomes possible. The camera is selected by the operation of a camera selecting means 5 and the camera is adjusted by using a camera adjusting means 6. The state under adjustment is displayed at a state display means 7. At the state display means 7, by turning ON a state display selecting switch 5a, camera numbers for discriminating the plural cameras and the state display items and the information of the cameras are arrayed in rows and columns and are simultaneously displayed. Thus, the difference of the states among the cameras can be obviously compared.

摘要： PURPOSE:To know the time of occurrence and the types of troubles of a TV camera without monitoring the occurrence of troubles at all times by recording both the trouble information and the time information into a memory means and displaying collectively the past trouble information. CONSTITUTION:A CPU 2 fetches the trouble information outputted from a trouble detecting circuit 1 and the time information outputted from a timer 5, respectively. Then, the CPU 2 controls a character display circuit 3 to output the character information in response to a monitor 4. Furthermore, the CPU 2 records these obtained information into a nonvolatile memory 6. When an operation switch 7 is pushed, the past trouble information recorded in the memory 6 are displayed together with the time information in characters on the monitor 4 via the circuit 3. Thus, it is possible to display later even such a trouble that occurred in an instant with no constant monitoring because the past trouble information are recorded together with the time information.

摘要： PURPOSE:To set a display device at an optional area and to display accurately a diaphragm value, by detecting the diaphragm value in the form of an electric signal and performing a digital display according to the electric signal. CONSTITUTION:The diaphragm value detected in the form of an analog signal is converted into a digital signal through an analog-to-digital converter A/D and furthermore converted into a display signal of the diaphragm value by a code converter CC to be applied to a display device DP. Thus the diaphragm value is displayed in a digital form. Accordingly, the diaphragm value can be easily confirmed while operating a camera by setting the device DP within a viewfinder or at an area near the viewfinder. At the same time, an accurate display is always possible regardless of the correlation between potentiometers RV1 and RV2 for rough adjustment and fine adjustment, respectively since a display corresponding to the diaphragm value is carried out.

摘要： PURPOSE:To eliminate moire electrically without lowering a resolving power, by extracting selectively a signal in a frequency band that induces the moire from a luminance signal and then supplying the extracted signal as a blanking signal of a modulator circuit. CONSTITUTION:The signals R, G and B supplied from the input terminals 1, 2 and 3 each are converted into the signals R-Y, B-Y and Y through the matrix circuit 4. Then each color difference signal is compounded with the signal Y after modulated by the modulator circuits 5 and 6 to be delivered to the output terminal 8 in the form of a color composite video signal. The signal Y is supplied to the band pass filter 9 to extract selectively only the signal that has a frequency band where the moire is caused. The selected signal receives a waveform shaping through the waveform shaping circuit 10 to be supplied to the circuits 5 and 6 in the form of the blanking signal. At this moment, the circuits 5 and 6 cut off the color difference signal.
