摘要
Disclosed is a multi-channel image combination output device for combining input image signals input through each of a plurality of input channels and outputting an integrated image to a display. The disclosed multi-channel image combination output device synchronizes input image signals and performs resolution. A first scaler group 110 for equally adjusting the values, line buffer pairs 120 for alternately storing odd line data and even line data, a second scaler group for reducing and scaling input image signals, and synchronization A first frame buffer to store the input image signals reduced and scaled by the second scalers in the second scaler group and the sync generator 170 that provides a reference image signal and a reference resolution when adjusting the resolution. And a frame buffer unit 140 including a second frame buffer, a first memory M1 and a second memory M2 for storing frames stored in the frame buffer unit, and frames stored in the frame buffer unit The control unit 151 and the frames stored in the first memory and the second memory are written to the first memory and the second memory, read frames stored in the first memory and the second memory, and provide them to the following image synthesis unit. It includes an image synthesizing unit 160 for generating an integrated image by synthesizing the image and outputting the integrated image to a display.
