Signal processing apparatus and control method thereof |
摘要 |
There are provided a signal processing apparatus and a control method thereof. The signal processing apparatus includes: 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 video signal having a level within a predetermined reference range; and a control unit which adjusts the reference range of the coring unit corresponding to the detected signal-to-noise ratio and controls the coring unit to core the video signal based on the adjusted reference range. |

1. A signal processing apparatus comprising:
a storage which stores a plurality of reference ranges corresponding to a plurality of signal-to-noise ratios; a noise detector which detects a signal-to-noise ratio of an input video signal; a coring device which performs coring to remove a component of the input video signal having a level within a reference range; and a controller which, by referring to the stored reference ranges, 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; wherein the controller adjusts the reference range based on a change in the signal-to-noise ratio; wherein if the change in the signal-to-noise ratio is an increase, the controller adjusts the reference range to be narrower; and wherein if the change in the signal-to-noise ratio is a decrease, the controller adjusts the reference range to be wider.
