Abstract: An optical fingerprint recognition system has a finger board. The finger board has a plurality of micro-structures, and a plate face of the finger board is to be in contact with a finger, and the other plate face of the finger board has an image capturing element and at least one light emitting element disposed thereon. The image capturing element and the light emitting element are separated from the finger board for a distance. When the light emitting element emits a light ray towards the finger board, the light ray is guided by the plurality of micro-structures to be uniformly distributed in the finger board, so as to facilitate the image capturing element to capture the light ray applied on the finger, thus improving the recognition rate of the fingerprint.

Abstract: An image coding system includes an image encoder and a predictive image decoder. The image encoder encodes an input image to obtain encoded data, compares the input image with a reference image, generates error information identifying parts of the input image that are changed with respect to the reference image, and outputs the encoded data and the error information. The predictive image decoder predicts the image, using a simplified prediction method for parts of the image identified by the error information as not being changed, and decodes the encoded data and the predicted data to obtain decoded image data. Use of the simplified prediction method in unchanged parts of the image reduces the prediction processing load without significant loss of prediction accuracy.

Abstract: The invention relates to a method and a device for coding video levels of pixels of a color component of a picture to be displayed on a display device into code words. The invention is more particularly applicable to Plasma Display Panels (PDP) to improve the picture quality (grayscale enhancement, dynamic false contour reduction). The main idea of the invention is to automatically change the floor and ceiling levels used classically for dithering each pixel value depending on the neighboring pixels of the same color component. The size of the window determining the neighboring pixels is dependent on the definition of the wanted flat field size.

Abstract: In MPEG, most video frames are encoded in inter mode. Every now and than a video frame is encoded in intra mode in order to limit error propagation and to enable access points for starting decoding of the video sequence. According to the invention, however, it is sufficient to encode in an intra frame only those pixel blocks in intra mode of which at least one pixel is used for predicting some future picture content information, whereas the other blocks can be encoded in inter mode. In order to check which blocks in the intra frame can be encoded in inter mode, a motion compensation pre-analysis of the following P-frame is performed, in order to find those blocks that need not be encoded in intra mode because no pixel in such blocks is used for the prediction of that following P-picture.
