ABSTRACT:
The input and output signal converter with a simple construction selects a voluntary internal video signal out of a plurality of internal video signals generated at an image processing unit for external output in addition to outputting a normal video signal. A selection unit 8 selects a plurality of internal video signals S7 generated at the image processing unit 3 and/or a plurality of external image input signals S1. A small-sized selection unit 15, which receives a plurality of internal video signals S7, selects the voluntary internal video signal S7 for output. With this invention, the voluntary video signal S7 can be selected out of the plurality of internal video signals S7 for output with a simple construction. Thus, the invention does not need to resort to a large number of switches which would, otherwise, require that the plurality of external input video signals S1 be selected in the first selection unit 2.
