Abstract

There is provided a video camera monitor that is capable of turning on a tally lamp without troublesome wiring even when a video camera does not have a tally signal output terminal. The present invention provides a video camera monitor that includes a camera video input unit and a tally display controller. The camera video input unit receives a camera video signal including a REC RUN time code, and the tally display controller controls tally display. The tally display controller controls the tally display based on whether the REC RUN time code is being advanced.

Claims

1. A video camera monitor comprising:

a camera video input unit that receives a camera video signal including a REC RUN time code; and

a tally display controller that controls tally display, wherein

the camera video signal does not include a tally signal, and

the tally display controller controls the tally display based on whether the REC RUN time code is being advanced.

2. The video camera monitor according to claim 1, wherein the camera video signal is an SDI signal.

3. The video camera monitor according to claim 1, further comprising:

a video display adjustor that adjusts a peaking level, a brightness level, and a contrast level;

a storage unit that stores an operational state adjusted by the video display adjustor; and

a video display setting switcher that switches an operation between the state stored in the storage unit and an initial state.

4. The video camera monitor according to claim 1, wherein:

the camera video signal includes an embedded audio digital signal; and

the video camera monitor further comprising;

an audio signal separator that separates the embedded audio digital signal from the camera video signal;

a DA converter that converts the digital signal separated by the separator into an analog signal; and

an analog audio output unit that outputs the converted analog signal.
