<P>PROBLEM TO BE SOLVED: To provide a direct print adapter for directly outputting a high-quality image to a printer by inputting a video signal or a digital image signal. <P>SOLUTION: In a video mode, each picture signal of video apparatuses 4 and 5 is divided into a color-difference signal and a synchronization signal by a video signal processing part 10; the color-difference signal is digitized by a signal conversion part 15; a switch of a data transfer direction changeover part 30 is changed over by control of an input/output control part 60; and image data of one frame portion is transferred to a memory 52. In a digital camera mode, image data from a digital camera 2 are introduced into the memory 52. In display time, the switch of the data transfer direction changeover part 30 is changed over; and image data from the memory 52 are transferred to a video signal decoding part 40, synthesized as signals for video output and displayed. In printing, image data on the memory are converted to data for color printing by a data processing part 50 and transmitted to the printer 7. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
