    Abstract: A video decoding apparatus and method for enhancing video quality of lower resolution than the resolution of a display of a terminal is provided. The video decoding apparatus includes a quality enhancer and a controller. The quality enhancer includes a resizer and quality enhancement filters, each configured to perform a different video quality enhancement operation, and to perform a quality enhancement process on a decoded video with at least one selected enhancement filter from among the quality enhancement filters and perform upscaling with the resizer. The controller selects at least one of the quality enhancement filters to be involved in the quality enhancement and sets up a processing sequence of the resizer and the at least one selected quality enhancement filter.

    Abstract: An image processing apparatus and an image processing method processing a graphic image are provided. An image processing apparatus including: a display unit; a first image output unit which outputs a first image signal; a second image output unit which outputs a second image signal and a transparency information with respect to the second image signal; an image mixing unit which outputs a third image signal mixing the first image signal and the second image signal by using the transparency information; an image processing unit which processes the third image signal to output to the display unit; and a control unit which extracts the transparency information from the second image output unit, and outputs a position information about which the second image signal is displayed in the display unit based on the extracted transparency information to the image processing unit.
