Apparatus and method for reproducing real colors in a video system

In a video system having a video signal display device for amplifying a certain video signal inputted from a video signal generating unit for display on a screen based on a set amplitude degree, a method for reproducing real colors of the video system, said method comprising steps of:

• outputting a control command when the video signal display device receives an input from a menu key operated by a user;
• outputting to the video signal display device a first test video signal, in which inherent RGB color sensitivity information of the video signal display device is included, based on the outputted control command;
• reading from an internal memory a second test video signal, in which inherent RGB color sensitivity information of the video signal display device is included, based on the outputted control command;
• synthesizing the first test video signal and the second test video signal for display on a screen in the video signal display device;
• adjusting an amplitude degree in accordance with an input from an up/down key when the up/down key is operated by the user during the display of the synthesizing step;
• and
• amplifying all video signals from the video signal generating device based on the adjusted amplitude degree for display on the screen.

An apparatus for reproducing real colors of a video system, comprising:

• a photographing device for detecting an RGB color sensitivity from a photographed video signal, for producing a first test video signal based on the detected RGB color sensitivity, and for synthesizing the photographed video signal and the first test video signal for an output;
• and
• a video signal display device for storing a second test video signal in which inherent RGB color sensitivity information thereof is included, for synthesizing the first test video signal and the second test video signal for display on a screen based on a request of a user, for adjusting an amplitude degree of the first test video signal until a color sensitivity of the first test video signal is the same as a color sensitivity of the second test video signal, and for amplifying all video signals from the photographing device based on the adjusted amplitude degree for display on the screen;
• wherein said video signal display device includes:
• a key input unit operable by the user;
• a display controller for outputting first and second control signals based on inputs from said key input unit;
• an OSD signal generator for storing the second test video signal in which the inherent RGB color sensitivity is included, and for outputting the second test video signal based on the first control signal;
• and
• a video signal processing unit for synthesizing the first and second test video signals for display on the screen based on the first control signal, for adjusting the amplitude degree based on the second control signal, and for amplifying all video signals from the video signal generating device based on the adjusted amplitude degree for displaying on the screen.

A method for reproducing real colors of a video system, comprising the steps of:

• detecting an RGB color sensitivity from a photographed video signal, producing a first test video signal based on the detected RGB color sensitivity, and synthesizing the photographed video signal and the first test video signal to produce a video signal for storage frame by frame in a photographing device;
• converting the video signal stored in the photographing device, and transmitting the converted video signal to a public network through a transmitting antenna in a television transmitter;
• receiving the converted video signal from the public network through a receiving antenna, separating the photographed video signal and the first test video signal from the received converted video signal, amplifying the photographed video signal for display on a screen based on a set amplitude degree, and storing the first test video signal in a video signal display device;
• when a menu key is operated by a user, reading a second test video signal, in which inherent RGB color sensitivity information of the video signal display device is included, and the first test video signal stored in the video signal display device, and synthesizing the first test video signal and the second test video signal for display on the screen;
• and
• when an up/down key is operated by the user, adjusting the amplitude degree based on an input from the up/down key, and amplifying all video signals received through the public network based on the adjusted amplitude degree for display on the screen in the video signal display device.
