Abstract
A scaler circuit is provided. The scaler circuit includes 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. Each of the first scaler and the second scaler generates a first image and a second image, respectively, having different resolutions from a single image using the line memory.
Claims21
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;
