Abstract: An image processing method applied to an image processing device is capable of implementing bitstream stitching technique after interrupting image processing process. The image processing method includes steps of processing the i-th slice of N slices in an image to generate a plurality of first processed data; storing the first processed data in a memory unit; once an interrupting request is generated according to a requested process, storing stitching information associated with the last first processed data after processing the i-th slice; stopping processing the image and executing the requested process according to the interrupting request; continuing to process the (i+1)-th slice of the N slices to generate a plurality of second processed data after the requested process is finished; and storing the second processed data after the last first processed data in the memory unit according to the stitching information.

Abstract: A compressing method is applicable to compress of an image at a fixed compression ratio, in which the image has a raw data. The compression method includes the steps of receiving the raw data with a predetermined length as a compression unit; compressing the compression unit into a compressed bit stream, wherein a total length of the compressed bit stream being not larger than a target bit stream length; when the total length of the compressed bit stream is smaller than the target bit stream length, appending a dummy code to the compressed bit stream, so that a bit stream length of the compressed bit stream with the dummy code is equal to the target bit stream length; and repeating steps until the raw data is compressed into an image bit stream.

Abstract: A mobile phone with a stepless motion function is provided and includes a mobile phone body, an upper cover which can be movably provided outside the mobile phone body, and a pushing device including a first end part and a second end part, wherein the first end part is fixedly provided at the upper cover, and the second end part is fixedly provided at the mobile phone body, whereby the upper cover can move at a constant velocity from a first position to a second position relatively to the mobile phone body. Therefore, the mobile phone with a stepless motion function of the invention enables the upper cover to move at a constant velocity at the mobile phone body to increase the tactile sensation of the mobile phone.

Abstract: An processing method is used for processing an image file of an image, in which the image is divided into a plurality of image blocks, and at least one row of the minimum coded units sequentially define the image as a plurality of bands. The processing method includes the following steps. An image file of an image is supplied, in which the image file includes a bit stream and exchangeable image file (EXIF) data. A band indicator of the EXIF data is read according to an expanded range. A segment in the bit stream corresponding to a band encompassed by the expanded range is decoded according to the read band indicator corresponding to the band of the expanded range, so as to obtain the band.

Abstract: The invention provides a video coding method. The method may include: receiving a set of video data for transmission; identifying at least two partitions from the video data, a first partition containing at least a portion of decoding information enabling a decoding of the video data, and a second partition containing at least a portion of information indicative of video content; encoding at least a portion of the first partition at an application layer of a system to generate partition protection information, the partition protection information allowing a recovery of first partition data when an error occurs to the first partition data; and transmitting the first partition, the partition protection information, and the second partition.

Abstract: This invention provides a method to speed up mode decision in video coding standards. It is based on the characteristics of mode distribution and the relationship among the modes of neighboring blocks. It compares the main steps of checking SKIP mode, checking if neighboring blocks have a same mode, checking the best mode, and checking each mode in all inter modes then selecting the best one of these modes. Compared to the H.264 reference software full search method, the simulation result shows that this method can save up to 66.81% of the total encoding time with a slight increase in bit rate and a negligible PSNR drop.

Abstract: A CORDIC method and a CORDIC architecture applied in vector rotation are disclosed. An elementary angles set is extended by representing the elementary angles as the arctangent of the sum of two single signed-power-of-two terms to an extended elementary angles set. A combination of elementary angles is found from the extended elementary angles set such that the residue angle error can be minimized. A quantized scaling factor is used to scale the combination of elementary angles after being micro-rotated.
