Image data output device and receiving device

摘要

Image data scaled by a scaling circuit (1) and then multiplied by a weighting factor by a weighting factor multiplier circuit (3) and an on-screen-display (OSD) data multiplied by a weighting factor by a weighting factor multiplier circuit (2) and then scaled by a scaling circuit (4) are combined together by a combining circuit (5) to generate composite image data and the resultant composite image data is accordingly reproduced.
