Abstract
An image processing device and an image processing method are used for processing a video data that includes a first bitstream and a second bitstream. The image processing method includes the following steps: decoding the first bitstream to generate a first frame; generating an intermediate image based on at least the first frame; and mixing the intermediate image and a buffered image according to a reference data to generate a pre-mixed image. The buffered image includes a second frame and a third frame which correspond to the second bitstream and the first bitstream, respectively.
Claims16
An image processing device, wherein the image processing device is coupled to a storage circuit and configured to receive a video data, and the video data comprises a first bitstream and a second bitstream, the image processing device comprising:
- a decoding circuit configured to decode the first bitstream to generate a first frame;
- a computing circuit coupled to the decoding circuit and configured to generate a reference data;
- a frame composer coupled to the decoding circuit and configured to generate an intermediate image based on at least the first frame and to store the intermediate image in the storage circuit;
- and
- an image pre-mixer coupled to the storage circuit and configured to mix the intermediate image and a buffered image according to the reference data to generate a pre-mixed image, wherein the buffered image includes a second frame corresponding to the second bitstream.
