Abstract
The present disclosure relates to an image processing apparatus and an image processing method capable of suppressing a deterioration in image quality. The image processing apparatus includes a threshold value setting unit which sets a threshold value for identifying a feature of neighboring pixels of a current block in an intra prediction process in encoding of image data according to a bit depth of the image data and a filtering processing unit which performs a filtering process on the neighboring pixels by using a filter according to the feature of the neighboring pixels identified by using the threshold value set by the threshold value setting unit. The present disclosure may be applied to, for example, an image processing apparatus.
Claims9
An image processing apparatus comprising:
- a threshold value setting unit which sets a threshold value which is compared with a value calculated by using a sample of neighboring pixels in order to identify a feature of the neighboring pixels of a current block in an intra prediction process in encoding of image data according to a bit depth of the image data;
- and
- a filtering process unit which performs a filtering process on the neighboring pixels by using a bi-linear interpolation filter in the case where the value calculated by using the sample of the neighboring pixels is lower than the threshold value set by the threshold value setting unit.
