Image data transmission unit 23: image input and the dateout of pretreatment unit or the dateout of digitized video compression unit are transferred to storing media, network or image display module.
The image data of commonly using is that whole image is transferred to the internet when transmission, but the pixel of digital camera is more and more high, image for same size, its data volume of the image of high pixel relatively also can increase a lot, difficulty when this will cause transfer of data, in order to transmit the image of high pixel, use the volume/decoder of more expensive high compression ratio possibly, could finish the transmission of image data smoothly.Thus, the cost of volume/decoding hardware will greatly promote.
Therefore, how conceiving one can effectively transmit its image data in response to high pixel video camera, and can not increase the digital image data transmission design of coding and decoding hardware cost, is concern person of the present invention.
Summary of the invention
The objective of the invention is to propose be combined into a plural number picture a kind of can cutting apart, each picture is the device of transmission after different compression standards are handled again, as this class video image monitoring products such as IP-CAM, Video Server, DVR, use the image data that transmits high pixel with the hardware of low compression ratio.Simultaneously can be at the picture that splits, transmission separately increases transmission speed.
For reaching above-mentioned purpose, the present invention proposes the circuit design that a kind of digitized video cutting compression is handled, and comprises:
One image input unit is used the numerical data that a digitized video is provided;
One digitized video cutting combinatorial logic unit electrically connects with this image input unit, uses the some of the numerical data of choosing this digitized video, and cuts and export the numerical data of this part;
One image compression unit electrically connects with this digitized video cutting combinatorial logic unit, uses the numerical data of this part of compression and exports;
One digitized video transmission unit electrically connects with this digitized video cutting combinatorial logic unit and this image compression unit, uses the numerical data numerical data of the part of this cutting maybe of this part of this compression of transmission.
The circuit design that described digitized video cutting compression is handled is to be applied to JPEG, Motion-JPEG, JPEG2000, MPEG1, MPEG2, MPEG4, H.264 to wait among the image transmission.
The circuit design that described digitized video cutting compression is handled, wherein this image compression unit is JPEG, Motion-JPEG, JPEG2000, MPEG1, MPEG2, MPEG4, H.264 waits encoder.
The circuit design that described digitized video cutting compression is handled, wherein this digitized video transmission unit system sees through digital data transfer to a storage device, a webserver or the display unit that the numerical data of being somebody's turn to do part that network should compression maybe is somebody's turn to do the part of cutting.
The circuit design that described digitized video cutting compression is handled, wherein this digitized video cutting combinatorial logic unit system can be divided into the numerical data of this digitized video complex digital partly, after utilizing this digitized video transmission unit to transfer to a receiving element, again by this receiving element should the plural number part the numerical data of digitized video make up back original complete image.
The present invention need not use the circuit of compressible one whole image when the image data of the high pixel of transmission, cost can greatly reduce, and the user also can choose desired compression coding mode by demand; Also optionally transmit the data of selected imaged frame in addition, reduce the transmission of image data.
