Title:
TELEVISION CAMERA DEVICE
Document Type and Number:
Japanese Patent JP3461621
Kind Code:
B2
Abstract:
PURPOSE: To easily ensure the color reproducibility of all TV cameras which are interlocking to each other by performing the individual correction of R, G and B signals and also applying simultaneously the same correction value to these three signals when three primary color signals of TV cameras are corrected.
CONSTITUTION: A TV camera device is provided with a means which simultaneously applies the color correction signals produced by the masking circuits 4, 5 and 6 to the R, G and B signals in the same correction value, a variable resistor 30 which simultaneously controls the chroma saturation of the basic R, G and B, a buffer 29, and the switches 31 to 34. The changeover switches 31 to 33 are turned on by a chroma saturation simultaneous control ON/OFF switch 34. As a result, the voltage controlled by the resistor 30 is applied to the DC amplifiers 23 to 25. Thus the simultaneous control of chroma saturation is attained.
