Abstract: A data processing system has a first data processing apparatus and a second data processing apparatus. The first data processing apparatus has at least a camera sensor, a compressor and an output interface. The camera sensor generates first input multimedia data. The compressor compresses the first input multimedia data into compressed multimedia data. The output interface packs compressed multimedia data into a bitstream. The second data processing apparatus has at least an input interface, a data access circuit, and a de-compressor. The input interface un-packs the bitstream into second input multimedia data. The data access circuit stores second input multimedia data into a multimedia buffer and reads buffered multimedia data from the multimedia buffer. The de-compressor de-compresses buffered multimedia data. Alternatively, one of the compressor and the decompressor may be implemented in a third data processing apparatus coupled between the first data processing apparatus and the second data processing apparatus.

Abstract: A data processing apparatus at a transmitter end has an output interface and a camera controller. The output interface packs a compressed multimedia data into an output bitstream transmitted via a camera interface. The camera controller refers to a compression characteristic of the compressed multimedia data to configure a transmission setting of the output interface over the camera interface. A data processing apparatus at a receiver end has an input interface and a controller. The input interface un-packs an input bitstream received via the camera interface into a compressed multimedia data. The controller configures a reception setting of the input interface over the camera interface in response to a compression characteristic of the compressed multimedia data. In addition, the data processing apparatus at the transmitter end may selectively enable a compression mode by checking the de-compression capability of the data processing apparatus at the receiver end.

Abstract: A method and apparatus for SAO (sample adaptive offset) processing in a video decoder are disclosed. Embodiments according to the present invention reduce the required line buffer associated with the SAO processing. According to one embodiment, tri-level comparison results for one deblocked pixel row or column of the image unit are determined according to SAO type of the deblocked pixel row or column. The tri-level comparison results are stored in a buffer and the tri-level comparison results are read back from the buffer for SAO processing of the subsequent row or column from a subsequent image unit. The comparison results correspond to “larger”, “equal” and “smaller” states. The comparison results can be stored more efficiently.

Abstract: An image capture device has an image capture module and a controller. The image capture module is used for capturing a plurality of consecutive preview images under an automatic shot mode. In addition, the image capture module can be a multi-view image capture module, which is used to capture a plurality of multiple-angle preview images. The controller is used for analyzing the preview images to identify an image capture quality metric index, and determining if a target image capture condition is met by referring to at least the image capture quality metric index. A captured image for the automatic shot mode is stored when the controller determines that the target image capture condition is met.

Abstract: A data processing apparatus has a first compressor, a second compressor, a first output interface, and a second output interface. The first compressor generates first compressed display data by performing compression upon display data of a first partial region of a frame according to a first compression order. The second compressor generates second compressed display data by performing compression upon display data of a second partial region of the frame according to a second compression order. There is a boundary between the first partial region and the second partial region. In a horizontal direction, the first compression order on one side of the first boundary is opposite to the second compression order on another side of the first boundary. The first and second output interfaces output the first and second compressed display data via a first display port and a second display port of a display interface, respectively.
