Abstract:
An apparatus for reproducing real colors in a video system, comprising:a video signal generating device for storing a first test video signal in which inherent RGB color sensitivity information thereof is included, and for providing the first test video signal as 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 based on a request of a user for display on a screen, for adjusting an amplitude degree of the first test video signal until color sensitivity of the first test video signal matches color sensitivity of the second test video signal, and for amplifying all video signals from the video signal generating 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.
