Abstract

본 발명은 칼라 비데오 프린터에 관한 것으로, 일반적으로 사용되고 있는 칼라 프린터에서의 프린팅 모니터 회로는 단순히 R.G.B 신호를 합성하여 만든 휘도 및 칼라 신호중에서 칼라 신호가 모니터에 점차적으로 나타나 칼라 색상이 점점 제 색상을 찾아가도록 동작시키고 있으나 이것만으로는 현재 프린트되는 색이 황색, 진분홍색, 청색중 어느 색인지를 알 수가 없게 됨으로써 사용자가 프린트의 진행 상황을 정확히 알 수 없는 결함을 가지고 있다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a color video printer. In general, a printing monitor circuit in a color printer is a color signal gradually appearing on a monitor among luminance and color signals obtained by simply synthesizing an RGB signal, and color color gradually finds a color. But this alone does not know whether the color of the current printing color of yellow, pink, blue, the user has a defect that does not know exactly the progress of the print.

이에 따라 본 발명의 목적은 상기와 같은 종래의 칼라 프린터의 프린트 지행표시회로의 결함을 해결하고자, 현재 프린트되고 있는 색상을 모니터로 표시함과 아울러 프린팅의 진행정도도 같이 표시하여 사용자가 프린팅의 진행상황을 시각적으로 확인할 수 있도록 하는 프린트 진행과정 표시회로를 제공하는데 있다.Accordingly, it is an object of the present invention to solve the defects of the printing process display circuit of the conventional color printer as described above, by displaying the color being printed on the monitor as well as the progress of printing with the user to proceed with printing It is to provide a print progress display circuit to visually check the situation.

Claims

Memory means for storing RGB image data input from the medium in color order, first switching means for receiving a color selection control signal from the outside and outputting data selected from RGB data stored in the memory means through an internal switching operation; And D / A converting means for converting the output digital data of the switching means into analog data, encoder means for inputting RGB data obtained from the D / A converting means and converting the result into luminance and color signals, and the brightness and color. Mixing means for mixing the signal to create a screen image signal and output to the monitor, and the second switching to input the switching control signal from the outside to the mixing means in accordance with the degree of printing proceeds from the encoder means Means, the first switching means and the second switching means A memory control gate array means, and the print process, characterized in that the display circuit configured by system 57 for generating a reference signal to the memory control gate array means for controlling its switching action.

The method of claim 1, wherein the D / A conversion means is coupled to the front end or the rear end of the first switching means.
