Classification: CPC G  H | IPC G

Claim 0:
1. A signal processing device comprising:
a frame buffer configured to store an input image and output an output image corresponding to the input image;
an output synchronization signal calculator configured to calculate an output synchronization signal based on an input synchronization signal and a size or a position of the output image in comparison with the input image; and
an output synchronization signal output interface configured to output a variable output synchronization signal of which a start timing changes based on a signal from the output synchronization signal calculator,
wherein a difference between a start timing of the input synchronization signal and a start timing of the output synchronization signal changes based on the size of the output image in comparison with the input image, and
wherein the difference between the start timing of the input synchronization signal and the start timing of the output synchronization signal changes based on the position of the output image in comparison with the input image.
