Abstract: According to one embodiment, an image processing apparatus includes a display area selector and a display manager. The display area selector selects a display area in a frame of video image data based on motion of a video image in the frame and a size of an application image displayed in the display area. The display manager combines the video image data with the application image data to generate display image data in such a manner that the application image is displayed in the display image area.

Abstract: According to one embodiment, an image processing apparatus includes a feature based detector, an optimum area generator, and an output data generator. The feature based detector detects a feature portion of input image data and generates feature area information showing a position of a feature area comprising the detected feature portion. The optimum area generator generates optimum area information showing a position of an optimum area in accordance with a size of the feature area based on the feature area information. The output data generator extracts pixels of the optimum area among the input image data based on the optimum area information and generates output image data based on the extracted pixels.

Abstract: According to one embodiment, an inverse discrete cosine transforming apparatus includes an inverse scan module, an inverse quantization module, a coefficient selector and an inverse discrete cosine transform module. The inverse scan module arrays a plurality of coefficients constituting decoded variable length data generated from bit stream of coded data in a predetermined scan order to generate inverse scan data. An inverse quantization module performs an inverse quantization on the inverse scan data to generate a discrete cosine transform coefficient. The coefficient selector generates an extending signal for each scan data. The inverse discrete cosine transform module performs an inverse discrete cosine transform on the discrete cosine transform coefficient based on the extending signal to generate decoded image data.
