Most preferred embodiment
Below in conjunction with drawings and Examples the present invention 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.IMAQ compression unit of the present invention, 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), (m≤n) original image coded data (stream) adopts two or more different image Compression mode (method) to compress processing to wherein optional m simultaneously, for example: different Standard of image compression (JEPG and MEPG), or different image resolution ratio (720 * 576 and 352 * 288), or different packed data code stream (4 Mbps and 1.15 Mbps), 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 memory device stores 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 device 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 Digital Image Processing recording method embodiment one of the present invention 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 (m≤n) individual original image vision signal is carried out two compression processing to appointing m.
Example 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 resolution ratios, or unit 25 frame/seconds of 102 usefulness and the compression frame per second of 6 frame/seconds of unit 103 usefulness ... Deng), handle through image Compression unit 102 and 103, make same original image information, formed two kinds of different packed datas (stream), then transported to Main Processor Unit and carry out stores processor by data/address bus 105.
When handling as above-mentioned two compressions, its acquisition process unit example 101 can be after carrying out digital coding via an analog-to-digital conversion and digital coding circuit, to be further divided into two identical data (stream) and to send into image Compression unit 102 and 103 respectively; Also receive original image vision signal 1 simultaneously, and after carrying out digital coding respectively, send into corresponding image Compression unit 102,103 again with two identical analog-to-digital conversion and digital coding circuit.
The rest may be inferred as stated above in all the other original images processing.
The Main Processor Unit 200 of present embodiment, each image compression data (stream) to data bus 105, carry out Classification Management and processing, and by data/address bus 201 such data (stream) are sent to unit records storage, the two kinds of image compression datas (stream) that will handle through different compress modes (method) wherein a kind of or partly image compression data (stream) be sent to write down in external memory or other system through data-interface (example: IDE, SCSI, IEEE1394, USB, SerialATA, LAN etc.) and store.
The memory cell 300 of present embodiment, form by one or more similar or dissimilar storage devices, (example: hard disk, data tape machine, CD writer, flash memory device etc.), memory cell 300 will write down image compression data (stream) respectively by the requirement of Main Processor Unit and store or read.
The Auxiliary Control Element 400 of present embodiment is made up of auxiliary signal unit 401 and supplementary command unit 402.Auxiliary signal unit 401 can will come from outside signal (example: the switching value signal) send Main Processor Unit after treatment to; Supplementary and command unit, can receive the information (data) and the instruction of outside input, and send Main Processor Unit to after handling, carry out system's control and data processing (example: the supplementary insertion processing in the selected control of compress mode or the packed data (stream) with auxiliary Main Processor Unit ... Deng).
The demonstration output unit 500 of present embodiment is with the view data (stream) through decompressing, or the original image through suitably handling reproduces and output (example: with AV or VGA mode).
Shown in accompanying drawing 3, Fig. 3 is an embodiment with computer rigid structure or similar structures.The picture in picture picture is gathered compression processing unit 100, Main Processor Unit 200, and memory cell 300, Auxiliary Control Element 400, image reproduction unit 500, these several partial functions are similar to previous embodiment.
The IMAQ compression processing unit 100 of preceding embodiment is that the image processing compressing card with computer bus (as pci bus) mode is formed in the present embodiment.
Preceding embodiment Main Processor Unit 200, in this enforcement, partly form by basic computer, comprise mainboard, CPU, internal memory, ide interface, pci bus etc., the decompression of image compression data (stream) in the present embodiment is to be finished and to handle with software mode by CPU element 202, and by display adapter unit 500 outputs.
