Embodiment Construction

[0046]In the present invention, a serial digital signal (hereinafter, referred to as an SDI (Serial Digital Interface) signal in this specification) of a TV camera device (master) serving as a reference for color signal adjustment is directly input to another computer for color signal adjustment. camera (hereinafter referred to as "slave" in this manual), and automatically adjust the image level of each channel of the slave device, so that the image level of the image signal of each channel of the master device is the same as the image level of each channel of the slave device. The image level of the signal is the same.

[0047] In addition, in the present invention, when a TV camera device and a camera control device (hereinafter referred to as a CCU (Camera Control Unit) in this specification) are used in combination, the video signal of the TV camera device is sent back from the CCU (hereinafter referred to as a CCU in this specification). It is called RET signal in the ins...

Abstract

Provided is a television camera using a solid-state imaging device, wherein color signal adjustment between TV cameras can be performed easily and quickly without relying on the level of skill of an operator. The serial digital signal of a TV camera (a master) acting as the standard for color signal adjustment is directly input into another TV camera (a slave) that adjusts the color signal, and the image level of each channel of the slave is automatically adjusted in a manner such that the image level of each channel of the master corresponds with that of the slave.

Description

technical field [0001] The invention relates to a method for adjusting color signals between television camera devices. Background technique [0002] In a studio such as a broadcasting station, a plurality of TV camera devices (hereinafter referred to as TV camera devices in this specification) are used simultaneously when producing one broadcast TV program. Here, when a plurality of TV camera devices are used, it is important to mention that there is no color difference among the TV camera devices. [0003] This is because, for example, when there is a color difference between TV camera device A and TV camera device B, when switching from the video captured by TV camera device A to the video captured by TV camera device B, the color tone of the video being broadcast will be different. Changes that make viewers feel uncoordinated. [0004] In order to solve the above-mentioned color deviation among the TV camera devices, when a plurality of TV camera devices are used at th...
