Projector device and projector system using the same

A projector device comprising:

• an operation unit which selects a projection mode for designating the number of split screens forming a projection frame, the location of each split screen, the size of each split screen, the orientation of each split screen, and graphical signal data that is to be displayed in each split screen;
• a plurality of input connectors respectively connected to a plurality of external graphical signal generators;
• a plurality of input units which each perform input signal processing on the graphical signal data provided to a corresponding one of the plurality of input connectors from a corresponding one of the plurality of external graphical signal generators to generate processed graphical signal data;
• a plurality of graphical signal processing circuits which each perform data conversion and adjustment in accordance with the projection mode selected by the operation unit on the processed graphical signal data generated by one of the plurality of input units to generate adjusted graphical signal data conforming to the size, location, and orientation of a corresponding one of the split screens;
• a synthesizer which combines the adjusted graphical signal data provided from the plurality of graphical signal processing circuits to generate combined graphical signal data;
• and
• a projection unit which projects the combined graphical signal data as a single projection frame.
