摘要:
Disclosed herein is a digital broadcasting receiving apparatus that can offer high-definition images with appropriate image quality correction by setting the quantity of image quality correction with reference to encoding information and image information in pixel blocks. The apparatus includes an image processing unit for performing image processing on decoded image signals. This image processing unit has a noise detection unit for detecting noise information for each pixel block based on encoding information of images included in digital broadcasting signals, a setting unit for setting the quantity of image quality correction based on noise information detected by the noise detection unit and image information for each pixel block of the decoded image signals, and a unit for performing image quality correction on each pixel block of the decoded image signals with the quantity of image quality correction set by the image quality setting unit.
