    摘要: A bit rate control circuit for image compression includes a compression unit, a R-value calculation unit, a linear quantization factor (LQF) calculation unit. The compression unit is used to performs a first quantization process on an image based on a default LQF (LQFini) to obtain an initial bits per pixel (bbpini) with an initial number of zero coefficients (Rini). The R-value calculation unit calculates out a target R value (Rtarget) based on the initial bits per pixel (bbpini), the initial number zero coefficients (Rini), and a target bpp (bbptarget). The LQF calculation unit calculates a target LQF (LQFtarget) based on the target R value Rtarget. The LQFtarget can be used to perform a second compression on the image to obtain a compressed image corresponding to the target bpp (bpptarget).

    摘要: A resin composition consists of a resin mixture, a light diffusing agent and a fluorescent-whitening agent. The resin mixture consists of 50˜99.9 wt % of polystyrene (PS) and 0.1˜50 wt % of polycarbonate (PC). The light diffusing agent is 0.1˜20 wt % of the resin mixture. The fluorescent-whitening agent is 0.00001˜0.02 wt % of the resin mixture. Therefore, the present invention has low cost because of PS and also possesses high thermal resistance and high impact resistance because of PC. Resin plates made from the resin composition, such as diffusion plates, have improved thermal and impact resistances.

    摘要: A method for performing a load flow test among a number of IEEE 1394 controllers is provided. The IEEE 1394 controllers are disposed on a number of interface cards individually while the interface cards are placed in a host or several hosts. The method includes the following steps: The interface cards are first initialized. Then, the master interface card starts to perform the load flow test. After that, the status of every interface cards is checked for confirming whether an error occurs or not. If the error occurs, debugging is performed. If not, the slave interface cards checks the result of the load flow test. The invention can fully control the buffer and monitor the memory since the test method is not performed under the driver structure in the WINDOWS operating system. It is therefore convenient to test in a load flow environment by using this method.

    摘要: Disclosed is an apparatus and method for generating a real-time stereoscopic image from depth map. According to the depth information of the image, a depth-image-based rendering (DIBR) algorithm is used to shift (or move) the position of the object in the image to generate the stereoscopic image with parallax. When the object is shifted (or moved) away from its original position, a hole will occur in the original position. Therefore an image inpainting algorithm is developed to fill the hole. In order to achieve the real-time application, a hardware architecture and method have been developed to accomplish the DIBR and image inpainting algorithm.
