Abstract:
1. An apparatus for converting multi-source input images, the apparatus comprising: an outside interface part comprising N outside interface units for pre-processing said input images; a format converting part comprising N format converters for converting formats and sizes of said pre-processed images as required by a display device, said pre-processing comprising at least one of processing each input image to have a fixed color format, processing each input image to have a fixed number of bits format, eliminating abnormal image data from each input image, and providing at least one of a size, frame rate, and scanning rate information of each input image to said format converting part; a memory part for interacting with each format converter and storing each pre-processed image or format-converted image; a switching part for switching said format-converted images according to a display mode; a multiplexer for multiplexing said switched images and generating a corresponding display image; and a display processor for processing said display image for said display device, wherein, depending on the display mode, when the converted format is to have an increased size with respect to size of said each pre-processed image, said format-converted images are output to said switching part by writing each pre-processed image to said memory part according to an input image clock and reading said written pre-processed image from said memory part according to the display image clock, and wherein, depending on the display mode, when the converted format is to have a decreased size with respect to the size of said each pre-processed image, said format-converted images are output to said switching part by writing to said memory part each format-converted image according to the input image clock and reading said written format-converted image from said memory part according to the display image clock.
