Abstract
An input processing section reduces the content of an input video signal according to reduction ratio data, and the reduced video signal is stored in field memories. A display processing section reads a reduced video signal from the field memories to execute window display processing thereto according to video size SIZ data and video position data (X, Y). In this event, an input video clock generator, controlling a writing operation to the field memories, computes video size SIZ data from the reduction ratio data, and writes the SIZ data as a header, along with the reduced video signal, into the field memories via the input processing section. The SIZ data is read to be output to the display processing section and a display video clock generator for controlling reading.
