Abstract: An exemplary image processing method includes the following steps: receiving an image input composed of at least one source image; receiving algorithm selection information corresponding to each source image; checking corresponding algorithm selection information of each source image to determine a selected image processing algorithm from a plurality of different image processing algorithms; and performing an object oriented image processing operation upon the source image based on the selected image processing algorithm. The algorithm selection information indicates an image quality of each source image and is generated from one of an auxiliary sensor, an image processing module of an image capture apparatus, a processing circuit being one of a video decoder, a frame rate converter, and an audio/video synchronization (AV-Sync) module, or is a user-defined mode setting.

Abstract: A projection-based frame is generated according to an omnidirectional video frame and an octahedron projection layout. The projection-based frame has a 360-degree image content represented by triangular projection faces assembled in the octahedron projection layout. A 360-degree image content of a viewing sphere is mapped onto the triangular projection faces via an octahedron projection of the viewing sphere. One side of a first triangular projection face has contact with one side of a second triangular projection face, one side of a third triangular projection face has contact with another side of the second triangular projection face. One image content continuity boundary exists between one side of the first triangular projection face and one side of the second triangular projection face, and another image content continuity boundary exists between one side of the third triangular projection face and another side of the second triangular projection face.

Abstract: A data processing apparatus has a compression circuit and an output interface. The compression circuit has a pre-processor and a compressor. The pre-processor receives a first input display data in a first color domain, and performs a color format conversion upon the first input display data to generate a second input display data in a second color domain, wherein the second color domain is different from the first color domain. The compressor performs compression in the second color domain, wherein the compressor is arranged to compress the second input display data into a compressed display data in the second color domain. The output interface packs an output display data derived from the compressed display data into an output bitstream, and outputs the output bitstream via a display interface.
