1. A scaler circuit comprising:
a first scaler configured to perform a first horizontal scaling operation after a first vertical scaling operation;
a second scaler configured to perform a second horizontal scaling operation after a second vertical scaling operation; and
a line memory which is shared by the first scaler and the second scaler,
wherein each of the first scaler and the second scaler generates each of a first image and a second image, respectively, having different resolutions from a single image using the line memory.
