20080218593 | MULTI-STREAMING WEB CAMERA CONTROLLING SYSTEM AND CONTROLLING METHODOLOGY OF THE SAME - A multi-streaming web camera controlling system and controlling methodology are capable of providing an original video data stream and at least one compressed video data stream for displaying demands of local host and for requested video data format(s) by remote hosts, respectively. The host can selectively display the original video data stream and transmit the compressed video data stream(s) through the Internet directly in order to satisfy the video requirements of both the local host and remote hosts. The multi-streaming web camera controlling system and controlling methodology can reduce the consuming system resource of the host for processing a video data stream. Therefore, the multi-streaming web camera controlling system and controlling methodology are capable of decreasing the cost of the host and improving the performance for processing video data stream with improved quality. | 09-11-2008 |
20080288698 | CARD READER CONTROLLING APPARATUS BASED ON SECURE DIGITAL PROTOCOL - The proposed invention discloses a card reader controlling apparatus based on Secure Digital (SD) protocol, which comprises a high-speed bus interface, at least one SD host, at least one SD connection interface and SDIO connection interface (SD/SDIO interface), at least one bridge, and at least one other specific memory card connecting interface. The card reader controlling apparatus according to the proposed invention is capable of directly accessing data from/to an input/output device compatible with the SDIO connection interface (e.g. an SD card) or one other specific memory card via the high-speed bus interface. Thus, multiple format conversions performed by other peripheral bus interfaces (such as an USB interface) as the prior art can be by-passed or eliminated. | 11-20-2008 |

The flexible printed circuit board comprises a data-transmitting interface, a non-volatile memory controller and at least one non-volatile memory disposed thereon. Therefore, the paper-shaped non-volatile storage device features as both of traditional paper and traditional non-volatile storage devices, such as instantly writing, manually binding, and outwardly visible content as provided by the traditional paper sheets, and digital information storage, repeatable editing and rapid search capability as provided by the traditional non-volatile storage devices. | 03-05-2009 |
20100011276 | STORAGE DEVICE FOR REFRESHING DATA PAGES OF FLASH MEMORY BASED ON ERROR CORRECTION CODE AND METHOD FOR THE SAME - A storage device for refreshing pages of a flash memory comprises a flash memory, an ECC detector and a controller. The flash memory has a plurality of pages, and each page comprises a data area for storing data and a spare area for storing error correction code (ECC) corresponding to the data. The ECC detector is used to get the number of error bits of each page. The controller coupled to the ECC detector is used for storing data and ECC in a first page to a second page when a number of used bytes of the ECC stored in a spare area of the first page exceeds a first predetermined value. A number of used bytes of the ECC stored in a spare area of the second page is less than the first predetermined value. The second page is a blank page. | 01-14-2010 |

20100014579 | IMAGE PROCESSING APPARATUS, METHOD AND INTEGRATED CIRCUIT - An image processing method, and an apparatus and an integrated circuit for implementing the method are adapted for use in a liquid crystal display. The method includes the steps of: determining which blocks in a decoded current frame are noisy blocks; finding, in a processed reference frame, a most similar reference block for each noisy block and generating a block velocity for each noisy block; and processing pixels that are in the noisy blocks having block velocities smaller than a liquid crystal response rate of the liquid crystal display, and that are not covered by after-images. The present invention utilizes the characteristics of liquid crystals to increase processing speed. | 01-21-2010 |
20100021076 | METHOD, APPARATUS AND INTEGRATED CIRCUIT FOR IMPROVING IMAGE SHARPNESS - In a method, apparatus and integrated circuit for improving image sharpness, the method includes the following steps: (a) labeling each of pixels in an image as one of an edge/texture type and a non-edge/texture type; (b) classifying each of the pixels that are labeled as the edge/texture type into one of a border point type, a transition point type, and a peak point type; and (c) using a shrinking/expanding filter to filter the pixels of the border point type, and subsequently using a high boost filter to first filter the pixels of the peak point type and then filter the pixels of the transition point type to sharpen the image. | 01-28-2010 |
20100061649 | METHOD AND APPARATUS FOR REDUCING BLOCK NOISE - Block noises at block boundaries are removed, but when a contour line in the original image matches a block boundary, the degree of block noise removal is adjusted and image quality is improved. An adaptive filter has a step of calculating the weight of pixels near the block boundary by a high-pass filter, and a step of determining an adjusted value for the pixels near the block boundary based on the weight. The pixel values near the block boundary are adjusted and block noises are removed. A low-pass filter is applied to pixels near the block boundary to determine a filtered value. The adjusted values of the pixels near the block boundary are determined by obtaining a weighted sum of the original pixel value and the filtered value. Because the high-pass filter recognizes the definition of pixels near the block boundary, and the low-pass filter reduces the difference between pixels near the block boundary, the adaptive filter outputs the adjusted value, and this value removes block noise while retaining image definition. | 03-11-2010 |
