    摘要: An image processing device includes an image acquisition module, a memory module, and an image signal processing module, for performing an image enlargement and enhancement. The image acquisition module sequentially reads in an image block, including a unit pixel matrix and an exterior pixel matrix, wherein each pixel matrix includes a plurality of pixels and each pixel is associated with a parameter. The memory module stores a plurality of predefined edge patterns. The image signal processing module compares a loaded image block with predefined edge patterns, and determines if it is an edge block. Then, the image signal processing module further classifies its pixels into two groups, and calculates a continuous separating boundary between the two groups. Finally, the image signal processing module enlarges an edge block by placing new pixels inside its unit pixel matrix, wherein the new pixel parameters are extrapolated from the two classified pixel groups to maintain a sharp edge boundary. For those that are not edge blocks, interpolations are performed by the image signal processing module to derive smooth enlargements.

    摘要: A shift register including shift register units controlled by first and second clock signals for generating an output signal. For each unit, in an active period, the first driving device drives the first switch device to activate the output signal, and the second driving device provides a voltage signal according to the first clock signal to drive the first switch device to de-activate the output signal. When the first switch device de-activates the output signal, the second switch device provides the voltage signal to serve as the output signal according to the second clock signal. In the active period, the voltage signal has a low level, and the first and second clock signals are set as alternating-current signals and are opposite to each other. In a blanking period, the voltage signal has a high level, and each of the first and second clock signals is set as a direct-current signal.

    摘要: DDR_SDRAM chips running at 1.5 clock rate are used for transferring image data from an image data source to a source driver in a display panel. In general, P DDR_SDRAM chips running at a 1.5 clock rate are used to store frame data in N frames. If the frame date in each of the N frames is n bits and the memory space in the DDR_SDRAM chip is m, then P is a smallest integer equal to or greater than N multiplied by (n/m). In data transfer in a frame, a line period is partitioned into N segments and each DDR-SDRAM chip is separated into (N−1) parts such that the parts are used to read different data in the different frames. In order to share I/O pins when using a number of DDR_SDRAM chips, the read/write sequence for the all DDR_SDRAM chips follows the same command and address.
