摘要： An image processing device includes a car navigation processing unit 12 for processing a WQVGA signal, a TV receiving processing unit 15 for processing an NTSC signal, and an image resolution converting unit 17 which carries out an image resolution conversion of the NTSC signal from the TV receiving processing unit 15 to a WQVGA signal. The TV receiving processing unit 15 includes a pixel aspect ratio converting unit 104 for carrying out a pixel aspect ratio conversion of character data acquired from a WQVGA-ready character-font set 2, and a graphics/TV image compositing unit 106 for compositing an output from the pixel aspect ratio converting unit 104 with the NTSC signal, and for outputting a composite signal to the image resolution converting unit 17.
