IMAGE SIGNAL CONTROL SYSTEM FOR PROCESSING MULTI-POINT SIGNALS

摘要

PURPOSE: An image signal control system is provided to reduce the hardware and prevent distortion of a control signal by receiving a multi-point external signals to directly control an image standard mode. CONSTITUTION: An image signal control system includes an interface control unit(130) for controlling an image standard mode signal processed in a decoder(100) by means of a plurality of serial signals and trigger signals. An A/D converter(160) converts a plurality of external control signals into digital data by means of sampling frequency. A memory(170) stores the quantized data from the A/D converter(160). An image data format unit(110) transforms the image standard mode signal from the decoder(100) via the interface control unit(130) into image frame data. A memory control unit(120) stores the image frame data through the data format unit(110) at the memory(170). A host bus(180) transmits the image data from the memory control unit(120) to the outside.
