Embodiment

Below in conjunction with drawings and Examples the utility model is further described.

Shown in seeing figures.1.and.2, present embodiment comprises five unit: the IMAQ compression processing unit, and Main Processor Unit, memory cell, Auxiliary Control Element shows output unit.The utility model IMAQ compression unit, n (n is a natural number) original image vision signal importing this unit carried out digital coding (example: adopt CCIR601, the CCIR656 standard), and the n behind the digital coding original image coded data (stream) carried out image Compression (example: press the MPEG series of ISO/IEC and the Standard of image compression that H.263 waits of ITU-T, also available WAVELET or other efficient coding, compress technique), simultaneously to wherein optional m (m≤n), original image coded data (stream) adopts two or more different image Compression mode (method), for example: different Standard of image compression (JEPG and MEPG), or different image pixel structure (720 * 576 and 352 * 288), or different packed data code stream (4Mbps and 1.15Mbps), or different digital frame per second (25 frame/seconds and 6 frame/seconds).

Main Processor Unit will be compressed the various image compression datas (stream) after the processing, carry out stores processor (example: classification, adding sign etc.) respectively, and select the mode and the storage device of storage.

Various image compression datas (stream) are recorded in the one or more similar of memory cell, or on the record carrier of inhomogeneous device (these install example: hard disk, data tape machine, CD writer, flash memory device etc.); A kind of image compression data (stream) can be recorded in this said memory cells in addition, another kind of image compression data (stream) is sent to external memory by data-interface (example: IDE, SCSI, IEEE1394, USB, SerialATA, LAN etc.), or stores in other system.

Auxiliary Control Element can offer Main Processor Unit with signal, instruction, the data that received where necessary, carries out system's control and data processing with auxiliary its.

The demonstration output unit will be exported by the image signal reproduction of Main Processor Unit decompress(ion), or directly will be properly handled back original image signal reproduction output.

Compress after the utility model Digital Image Processing tape deck embodiment one adopts two kinds of different compress modes (method) to an original image collection and handle and store respectively or transmit processing, and operation is controlled to be by programme controlled automatic or semi-automatic carrying out.IMAQ compression processing unit 100, can receive n (n is a natural number) real-time original image vision signal simultaneously, and each original image vision signal (routine original image 1) is sent into two

image Compression unit

102 and 103 respectively after image acquisition and processing unit 101 carries out analog-to-digital conversion and digital coding.Handle by different compression processing mode (method) that (example: unit 102 adopts MPEG-1 and unit 103 adopts the JPEG compression standards, or unit 102 with 352 * 288 unit 103 with 720 * 576 image pixel structures, or unit 25 frame/seconds of 102 usefulness and the compression frame per second of 6 frame/seconds of unit 103 usefulness ...
