PURPOSE: An analog interface device of a digital image processor is provided to directly connect a digital video processor with a display by generating an output signal of an analog interface format loading a video signal with synchronous signal information. CONSTITUTION: A first mapping table(10) converts a pure video signal passed through a video processor into a digital value within an upper 0.7V region. A second mapping table(20) converts a synchronous signal into a designated value by using a digital signal processing method of two bits. A mixer(30) mixes the video signal processed in the first mapping table with the synchronous signal processed in the second mapping table. A DAC(Digital-to-Analog Converter)(40) converts a digital channel value mixed by the mixer into an analog channel value for outputting the analog signal to a monitor(50). |
