Zusammenfassung:	An analog/digital color video apparatus for adjusting attributes of a color image contained in an analog video signal and a digital video signal and visually displaying an attribute-adjusted color image on a display is provided. When an attribute of an analog video signal having a relatively lower definition is adjusted, the analog/digital color video apparatus converts the analog video signal into a digital signal and adjusts the attribute of the digitized video signal. When an attribute of the digital video signal having a relatively higher definition is adjusted, an attribute of a color image contained in the digital video signal is adjusted without a supplementary signal conversion process such as A/D conversion and D/A conversion. Thus, the analog/digital TV prevents quantization noise which can be occurred in the process of adjusting attributes of the color image.
