    摘要: In an image compressor, a color space converting unit separates an image data into a luminance data and a chrominance data. An image block-dividing unit block-divides each of the luminance and chrominance data separated by the color space converting unit into a plurality of blocks each of which includes adjacent pixels. A luminance threshold value determining unit determines a threshold value for binarizing the luminance data. A luminance binarizing unit binarizes the luminance data using the determined threshold value. A typical value forming unit forms two typical values for each of the block-divided luminance and chrominance data in accordance with the luminance data. A binarized luminance compressing unit encodes the binarized luminance data using dictionaries whose number is smaller than the number of all combinations of the luminance data.

    摘要: A recording and/or reproducing system has a recording and/or reproducing section and an interfacing unit. The recording and/or reproducing section records and/or reproduces digital data or digital signals on or from a loaded recording medium, such as a magnetic tape. The interfacing unit has a first input/output section for exchanging data and/or signals with an external equipment and a second input/output section for exchanging data and/or signals with the recording and/or reproducing section. The interfacing unit converts data and/or signals supplied from the recording/reproducing section through the second input/output section and sends the converted data and/or signals through the first input/output section to the external information equipment piece, while converting data and/or signals supplied through the first input/output section from the external information equipment piece and sending the converted data and/or signals through the second input/output section to the recording and/or reproducing section.
