  • Patent number: 7606440
    Abstract: In a linear image sensing device with image matching function, a linear sensors array senses a finger, which is moving over it, to obtain fragment image analog signals, which are amplified, by a programmable gain amplifier, into amplified signals. An analog-to-digital converter sequentially converts the amplified signals into digital image signals. An image matching module sequentially receives and processes adjacent two of the digital image signals, and outputs continuous non-overlapped fragment images through an input/output interface. A control logic controls operations and communications of the above-mentioned components. A terminal system receives the non-overlapped fragment images and assembles the non-overlapped fragment images into a complete fingerprint image in a manner of stacking the images side by side.

  • Patent number: 6151409
    Abstract: We discloses an efficient method for compressing a color image, visual block pattern truncation coding (VBPTC), in which the conventional block truncation coding (BTC) serves to encode an original image. This method defines the edge block according to human visual perception. If the difference between the two quantized values of BTC in a block is larger than a threshold which is defined by visual characteristics, the block will be identified as an edge block. In an edge block, the bitmap is adapted to compute block gradient orientation and to match the block pattern.

  • Patent number: 6118901
    Abstract: The invention discloses a 9-cell array architecture with data-rings for 3-step hierarchical search (3SHS) block-matching algorithm. With the efficient data-rings and memory organization, the regular raster-scanned data flow and comparator tree-like structure can be used to simply internal I/O controller and reduce latency. In addition, we can utilize techniques to reduce external memory accesses and interconnections. The results demonstrate that the array architecture with the data-rings is low in terms of latency, memory bandwidth and costs and a high performance solution for the 3 SHS.
