Abstract
본 발명은 비디오 검사 신호 발생기에 있어서 특히 프로그래머를 컬러-바 발생기에 관한 것으로서, 전체회로의 제어 및 동작을 운영하는 범용 마이크로 프로세서와, 인터페이스 회로에 의해 상기 마이크로 프로세서와 연결되는 컴퓨터 시템과, 디지탈화한 화상 데이타를 기억하는 리프레쉬메모리부와, 상기 마이크로프로세서에서 출력되는 어드레스 신호, 또는 데이터신호를 받아서 상기 메모리부에 입력되는 어드레스 신호와 데이터 신호를 전환하는 콘트롤 조직부와 상기 마이크로 프로세서로부터 신호를 전달받고, 상기 콘트롤 조직부의 선택에 따라 동작하는 데이터버스중재기 및 어드레스 버스중재기와 클락발생기로부터 클락신호를 받아서 귀선소거시간 계산 및 동기신호를 발생시키는 화소클락발생기와, 상기 화소 클락발생기의 출력신호를 카운트하여 메모리부의 어드레스를 만드는 어드레스 카운터부와, 상기 화소클락발생기로부터 동기신호 및 상기 어드레스 카운터에 의한 어드레스 신호에 대응하는 메모리부의 데이타를 읽어들여, 이를 아날로그 신호로 변한시키는 디지탈-아날로그 변환기와, 상기 디지탈-아날로그 변환기에 의하그런데 아날로그 신호로부터 비디오 신호를 발생시키는 비디오 변조기를 구비하여, 사용목적에 라 컬러-바 ㅅ니호 및 패턴을 용이하게 변경하여 발생시키며, 그 발생된 신호를 나타내는 표시부와 일체로 구현하는 것이 가능한 프로그래머블 컬러-바 발생기를 제공한다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a color-bar generator, in particular a video inspection signal generator, comprising a general purpose microprocessor for controlling and operating the entire circuit, a computer system connected to the microprocessor by an interface circuit, and A refresh memory unit for storing image data, an address signal output from the microprocessor, a control organization unit for receiving an address signal or a data signal and converting an address signal and a data signal input to the memory unit, and receiving a signal from the microprocessor, A pixel clock generator which receives a clock signal from a data bus mediator and an address bus mediator and a clock generator that operates according to the selection of the control organization unit, and calculates a blanking time and generates a synchronization signal, and outputs the output signal of the pixel clock generator. An address counter unit for mounting an address of the memory unit, a digital-to-analog converter for reading data of the memory unit corresponding to the synchronization signal and the address signal by the address counter from the pixel clock generator, and converting the data into an analog signal; A digital to analog converter is provided with a video modulator for generating a video signal from an analog signal, and is easily generated by changing a color-bar signal and a pattern according to the purpose of use, and integrally with a display unit indicating the generated signal. Provides a programmable color-bar generator that can be implemented.
