    摘要: A stereophonic image may be enhanced by splitting the left and right input audio signals into a plurality of left and right output signals in a plurality of audio frequency bands and then generating left and right output audio signals from the left and right output signals based on the magnitude of the differences between corresponding left and right output signals and also based upon the absolute magnitude of the left and right input audio signals themselves. In particular, a stereophonic image enhancement device according to the invention processes a left input signal and a right input signal using a first spectrum analyzer and a second spectrum analyzer which output a plurality of left output signals and right output signals corresponding to a plurality of frequency bands in response to the corresponding left input signal and right input signal. A table lookup signal is responsive to the plurality of left output signals and to the plurality of right output signals to output a plurality of left output signal pairs and a plurality of right output signal pairs. A first and second adder are responsive to the plurality of left output signal pairs and right output signal pairs respectively to add the output signal pairs and produce final left output signals and right output signals respectively.

    摘要: In the scanning conversion apparatus, interlaced-to-progressive scanning is performed according to one of at least two different techniques. The technique used depends on the interlaced scan data being converted. As examples, a spatial interpolation technique, a spatial/temporal interpolation technique, or other technique may be selected.

    摘要: A joint photographic expert group (JPEG) Huffman table decoder and a method thereof based on a binary search technique. The JPEG Huffman table decoder performs symbol matching based on the binary search and calculates an address of the matched symbol in code book data. Comparison time and an amount of memory required for searching the symbols are reduced.
