Abstract:
1. A video signal processing apparatus comprising: a processing unit configured to perform a decoding process to an inputted digital video signal to add a digital OSD signal, the digital OSD signal being set for display on a panel having the particular number of pixels; a conversion unit configured to digitize an inputted analog video signal; a scaling unit configured to selectively perform a first scaling process to the digital video signals outputted from the processing unit and the conversion unit while performing a second scaling process to the OSD signal, the scaling unit adding the OSD signal to which the second scaling process is performed to the digital video signal to which the first scaling process is performed outputted from the conversion unit; and a scaling data change unit configured to change display modes of the digital video signal and the OSD signal by causing pieces of scaling data to be variable based on a predetermined operation, the pieces of scaling data being supplied for the first and second scaling processes.
