摘要： PURPOSE:To always and appropriately execute white balance adjustment and to eliminate an optical color temperature correction filter at the time of a change in the color temperature of an illumination light by adding correction data to control data for white balance adjustment. CONSTITUTION:The operator of a camera switches color temperature switching signal S in accordance with the color temperature of the illumination light of a subject. A selection switch circuit 23 selects a color temperature data file 20 when the color temperature is 4700 deg.K in accordance with the switching. Thus, color temperature data corresponding to the color temperature of 4700 deg.K is inputted to an adder 24, is added to a control data from a file 9 and supplied to respective signal processing devices 6-8, whereby white balance adjustment of output video signals (r), (g) and (b) corresponds to the color temperature of 4700 deg.K and it comes to an optimum state. If color temperature similarly changes to other temperature, the signal S is switched, whereby either files 21 or 22 is selected, correction data is added to control data and optimum white balance adjustment can be obtained.

摘要： PURPOSE:To make it possible to correct the distortion of a picture image with high accuracy with a small scale circuit by merging distortion correction waveforms generated fro two distortion correction waveform generating circuits and correcting the distortion of a picture image. CONSTITUTION:Each corrected output from a low grade deflected distortion correction waveform generating circuit 30, a four cornors independent correction waveform generating circuit 31 and a digital system correction waveform generating circuit 32 are inputted to a deflecting circuit 33 in a red color channel horizontal direction. This corrected waveform is piled up on a horizontal saw tooth waveform 34 and after converted to current, it is outputted to a deflecting coil 35 and a deflecting distortion is corrected. So that it is possible to suppress the deflecting distortion of a picture under 0.6% when a low grade deflection correction waveform and a four cornors independent correction waveform are merged, the corrected waveform by a digital system does not change so much and the generation of shading is prevented and also,the memory size of the digital system correction waveform generating circuit 32 is restrained less than normal and it is constituted with a small scale circuit because a correcting capacitance in the digital system is enough with a six bits length. Thereby, it is possible to obtain a picture image distortion correction with high accuracy.

摘要： PURPOSE:To eliminate hindrance to the automatic setup operation of all TV camera even if a fault occurs to any of camera regulators (ASU), by monitoring operation states of plural ASUs through a switching device. CONSTITUTION:A data transmitter and receiver 5 monitoring voltages EA and EB from cables 11A and 11B through a time-division switch 8B and when they are present, a switching signal is supplied to a switch control circuit 4 to connect ASUs 1A and 1B to TV cameras 2A-2C. If a fault occurs to the power circuit of the ASU1A while the ASU1A is put in operation to connect with the TV camera 2A, the voltage EA is ceased, so the data transmitter and receiver 5 judges that the ASU1A is faulty, and then sends a signal to the switch control circuit 4 to change contacts of a selection switch 7A. Consequently, the TV camera 2A is disconnected from the ASU1A and switching to automatic setup operation by the other ASU1B is performed at need.

摘要： PURPOSE:To enable effective self-diagnosis of a camera by displaying an error value obtained by comparing each color channel output of a color television camera and signals of each part with the reference values on a vedeo monitor. CONSTITUTION:Outputs R.G.B of each color channel of a color television camera are selected by a selector SEL1 and given to an input of a differential amplifier DA through a selector SEL2. Only the output G is applied to other input of DA through a selector SEL3. Output levels L1-Ln of each part of the camera, voltages V1-Vn and a control pulse P are connected to an SEL2, an SEL3 through an SEL4. Each error signal that uses as G a reference value is obtained from DA. This is AD-converted and applied to a CPU. The CPU stores the error value in an RAM basing on a program from an ROM. The contents of the RAM are converted to character signals by a character generator CG, and mixed with video signals Sv in a mixer MIX, and displayed on a video monitor VM.

摘要： PURPOSE:To stabilize the generating position of an error-detecting pulse by positioning horizontal and vertical positions of screen in equal intervals and by generating an error-detecting pulse fully digitally by a pattern generating memory. CONSTITUTION:In the generating circuit for the error detecting pulse of a video signal, microcomputer 21 assings the position for error detection in an equally divided screen and the data of the position assignment and the data for assigning the kind of its error detection pulse are supplied to digital memory 25. Address counter 24 generates pulses, assigning respective horizontal and vertical positions to be divided, by pulses from frequency multiplying circuit 23 and digital memory 25 is then scanned to read the existence of the error detection pulse, and is sent to pattern-generating digital memory 26 to be output. At a position predetermined by memory 26, a pattern signal linear in the screen vertical direction is generated for pulse shaping 27. Consequently, the generating position of error-detecting pulse 28 is stabilized.

摘要： PURPOSE:To prevent erroneous control by detecting whether lamps of a pattern projector are disconnected or not and interrupting execution of auto-setup to display this state if they are disconnected. CONSTITUTION:Individual color lights of R, G, and B from light source lamps 3, 4, and 5 are condensed by a condenser 6 and are applied to a pattern projector 7. These optical information are separated to individual optical information of R, G, and B by a color separating optical system 9, and they are converted photoelectrically by image pickup tubes 10, 11, and 12. Signals from image pickup tubes 10, 11, and 12 are supplied to video processing circuits 13, 14, and 15. Video signals from these video signal processing circuits are supplied to an auto-setup 16 with a CPU as the center and are so operated that color balance information are equal to one another, and they are fed back to video signal processing circuits 13-15. If disconnection of projector lamps 3-5 is detected, the operation of the auto-setup circuit is interrupted by a signal from a detecting circuit 8, and abnormality is displayed on an error display device 17.
