1. A signal processing apparatus comprising:
- a noise detecting unit which detects a signal-to-noise ratio of an input video signal;
a coring unit which performs coring to remove a component of the input video signal having a level within a reference range; and
a control unit which adjusts the reference range of the coring unit according to the detected signal-to-noise ratio and controls the coring unit to core the video signal based on the adjusted reference range.
