Abstract: A semiconductor for decoding coded image and audio data, which includes an audio processor that decodes coded audio data, and an image decoder that decodes image data. The image decoder removes coding distortion in pixels of two adjacent transform blocks which are motion-compensated, having a coded motion compensation error equal to zero, and are located inside a same macroblock. The image decoder includes a motion compensation block boundary detector that determines whether the motion compensation error of the two adjacent transform blocks located inside the macroblock is zero, and determines whether a boundary of two adjacent transform block is also a boundary of two adjacent motion-compensation blocks. The image decoder also includes a filter that removes coding distortion in pixels of the two adjacent transform blocks, and a selector that selects whether or not the filter removes the coding distortion based on the determination of the motion compensation block boundary detector.

Abstract: A method and apparatus for motion blur and ghosting prevention in imaging system is presented. A residue image is computed by performing spatial-temporal filter with a set of absolute image difference of image pairs from input images. A noise adaptive pixel threshold is computed for every pixel based on noise statistics of image sensor. The residue image and the noise adaptive pixel threshold are used to create a motion masking map. The motion masking map is used to represent motion and non-motion pixels in pixels merging. The pixels merging step is performed to generate an output image by considering the motion pixels where the motion pixels are performed separately. The resulting output image having no or less motion blur and ghosting artifacts can be obtained, even the input images having different degree of motion blur between each of the image, while the complexity is low. It is preferred that the current invention is applied in the Bayer raw domain.

Abstract: An LSI device for decoding a coded image segmented and coded in a plurality of blocks. The LSI device includes a section which receives a filter selection parameter that determines a threshold value for each quantization parameter, for changing between conducting and non-conducting a coding distortion removal by the use of a filter. A decoder, decodes a coded block to obtain a reproduced image. A remover, removes a coding distortion from a region including both sides of a block boundary between adjacent decoded blocks that form the reproduced image, in accordance with a comparison of a difference value of the pixels in adjacent decoded blocks with the threshold value determined based on the filter selection parameter, such that the coding distortion removal is not conducted when the difference value is greater than the threshold value. The coding distortion removal is conducted by the use of the filter when the difference value is smaller than the threshold value.

Abstract: A liquid crystal display includes a liquid crystal panel and a height adjustable base. The height adjustable base further includes a main base, a fixing frame and an elastic locating device. The main base provides at least a sliding rail, which has a stationary member attached to the main base and a movable member capable of sliding along the stationary member. The fixing frame is connected to the movable member for being mounted with the liquid crystal panel. The elastic locating device provides an acting end, which is disposed against the fixing frame for supplying an elastic ascending force to the fixing frame, and a joining end, which is detachably connected to the main base with an elastic coupling force for restoring the elastic ascending force automatically. Therefore, the liquid crystal display can be simply operated to release or restore the ascending elastic force needed at the time of height adjusting the liquid crystal panel.

Abstract: A quantization matrix used in inverse quantization is generated. A received bitstream includes a coded truncated quantization matrix. The coded truncated quantization matrix has first coded bits and second coded bits. The first coded bits include bits obtained by coding a transmitting part of quantization elements and the second coded bits includes bits obtained by coding an end code. The coded truncated quantization matrix is decoded until the second coded bits corresponding to the end code are read out, to obtain the transmitting part of quantization elements. At least one additional quantization element is obtained. A complete quantization matrix is generated, using the transmitting part of quantization elements and at least one additional quantization element, by ordering the transmitting part of quantization elements and at least one additional quantization element in a zig-zag scan.

Abstract: A liquid crystal display with a height adjustable base assembly includes a base, a main arm, which is provided with a pivotal connection with the base and has slide rails, a panel fixing frame, which is capable of ascending and descending along the slide rails of the main arm and has a lock rod. A plumbing stop block is pivotally connected to the main arm to correspond to the lock rod. When the main arm rotates a preset inclining angular position with respect to the base, the plumbing stop block is urged to rotate by the gravity thereof for the lock rod being pushed to engage with the locating groove of the plumbing stop groove such that the operation of lifting the panel fixing frame with respect to the main arm is locked. Hence, the liquid crystal panel bouncing outward suddenly during unpacked is avoided to secure the safety with convenient operations.

Abstract: Mosaic-shaped block noise occurs when a compressed video signal is reproduced. This block noise is removed, but removing block noise from every block using a deblocking filter imposes a significant load on the deblocking filter. This load is therefore reduced by determining whether coding distortion removal (deblocking) is necessary, and applying a deblocking filter only when needed.

The method removes a coding distortion in a block block which is included in a macroblock of a frame structure, and which is not adjacent to a boundary of a macroblock of field structure. A coding distortion in a block which is included in a macroblock of the field structure, and which is not adjacent to a boundary of a macroblock of the frame structure is then removed, and a coding distortion in a block which is adjacent to both a macroblock of the frame structure and a macroblock of the field structure is removed.
