Fig. 2 is according to a preferred embodiment of the present invention, and it illustrates the breakout box communication to each other of a principal computer and Fig. 1.
Embodiment
Fig. 1 is according to the analog or digital dynamic image video camera 10 of one embodiment of the invention or the breakout box 300 of a still image video camera 20.By diagram, breakout box 300 is small sizes and is included in the casing that this casing is also littler than dynamic image video camera 10 employed volumes.More preferably, the casing of breakout box 300 can be designed to directly be installed on the casing of dynamic image video camera 10.Yet in one embodiment, breakout box 300 is to be designed to and can be connected with size with the shape of various dynamic image video cameras 10, and it does not need to be directly connected on the casing of dynamic image video camera 10.Breakout box 300 also can be installed among the casing design of suitable dynamic image video camera 10.
As shown in the figure, a composite picture signal, as NTSC, PAL, specifications such as S-video are exported from a simulation dynamic image video camera 10, and are inputed to an image decoder 305 via the first image input end 301 on the breakout box 300.Typical composite picture signal comprises a digital color image signal, and it comprises I and the Q colour component signal that is overlapped on the monochrome signal M.Monochrome signal M comprises analoging brightness (luminance) signal between the level of being scattered in and vertical marker pulse signal.Image decoder (video decoder) 305 be signal M, I, and Q separates from composite picture signal.Image decoder 305 is from signal M, I, and Q replys brightness signal Y and chrominance signal C rWith C bOr signal R, G, B, but can remove control signal, as level and vertical marker pulse signal.By sampling analysis etc., the signal that receives is produced data image signal.In brief, image decoder 305 is with digital form, and produces the answer portrait signal (removing carrier signal and control signal) of a sequence.
In the present embodiment, breakout box 300 also has traffic pilot 310.Wherein, second input end 302 is in order to receiving a numeral portrait signal from a digital camera 20, and traffic pilot 310 then receives numeral that this numeral portrait signal and image decoder 305 produced and draws a portrait signal.Then, traffic pilot 310 is selected signal according to one again, selects a conduct output in two inputs.In the present embodiment, the selection signal may be from a peripheral operation switch or from image processor (videoprocessor) 330.
Traffic pilot 310, via image bus or title V-BUS, the composite picture signal that output is selected is to image processor 330.Illustrated image processor 330, it can be served as reasons and be positioned at the magnificent nation system experimentation chamber in holy He west, California TMThe W9962 of manufacturing TMThe image compression/decompression processor.This image processor 330 receives from the composite picture signal of traffic pilot 310 outputs.Select signal according to one, it can be produced (as the keyswitch on the breakout box 300 or the principal computer 120 that is connected) by the outside or be produced by the image processor 330 of inside, and image processor 330 is selected portrait from composite picture signal acquisition one.By diagram, this selects portrait to be stored in frame buffer 350, and frame buffer 350 can be made of DRAM.This can be finished by following method.Composite picture signal outputs to image processor 330 from traffic pilot 310.By diagram, this composite picture signal also outputs to a LCD display 30, or outputs to a television screen 35 (hereinafter having more detailed explanation) via an image encoder 370.When each image of composite picture signal was received by image processor 330, image processor 330 was via the DRAM bus or claim that D-BUS outputs to frame buffer 350 with image.Catch when getting that wherein a dynamic image is as still image (for example correctly to defocused, the image that is presented on LCD display 30 or the television screen 35 is formed) when user decision, the user produces one and selects signal.According to the selection signal that the outside produces, the image in the image processor 330 instant condensed frame impact dampers 350, and the image transfer that will compress is to non-volatile impact damper 360.
Image processor 330 is processors of a programmable, according to various static state and moving image format, provides various compression of images and decompression, and this type of form comprises JPEG, MPEG, and MPEG-2, H.263 etc.Hereinafter have more detailed explanation.Special compressed format can and can be uploaded to image processor 330 by principal computer 120 or from non-volatile impact damper (nonvolatile buffer) 360 by user's selection.The image that compressed can lower the capacity of storage.For example, suppose that original image is 525 * 352 pixel sizes.This image can convert 640 * 480 pixel sizes to by image encoder 305 (using removal method and extrapolation), with 3/pixel, and the pattern of RGB.Store this type of image and need 921,600 bytes (bytes is called for short B).Memory space can greatly reduce (view picture and various selection parameter and decide) when using JPEG compressed format.For example, in jpeg format, the preferable image image quality is recently reached with 20: 1 compression usually, and therefore reducing memory space is 46KB, and the memory space of using higher ratio of compression 10-25KB also is to reach.
Image processor 330 can be selected portrait from optionally non-volatile impact damper 360 storages one, and non-volatile impact damper 360 can be made of the flash memory of position on removable flash memory card (removable flash card).By diagram, for saving storage space, image will compress earlier before storage.In addition, the portrait of the selection after the compression also can export a radio-frequency module (RFmodule) 355 to from image processor 330.Radio-frequency module 355 modulations are at a carrier signal epigraph signal, and modulating signal is reached a far-end receiver (remote receiver).This radio-frequency module 355 can be used on image teletype conference system.For example, receiver can be the part of image meeting, is used for receiving the picture signal that transmits and this picture signal is sent to a far-end platform via telephone network.At the far-end platform, picture signal is decoded and be presented on the far-end video screen.Therefore, breakout box 300, in the application of teletype conference for video camera provides bigger activity space, because video camera does not link together with other equipment of teletype conference.In like manner, before exporting radio-frequency module 355 to, be favourable with compression of images to saving the communication frequency range earlier.
The image of acquisition also can export an external device (ED) to via interface 340, as the principal computer 120 of Fig. 2.By diagram, interface 340 is a kind of universal serial maincenter (Universal Series Bus hub is to call USB hub in the following text).Basically, USB hub 340 is a kind of bi-directional serial interfaces, in order under the low rate that is provided at 1.2Mbit/sec or the data under 12Mbit/sec speed faster transmit.Multiple USBhub can connect into a tree structure.After the image of one 1024 * 768 resolutions compresses with a ratio of compression at 20: 1, can finish in speed download via USB interface 340 less than 0.1 second.
The advantage of USB hub 340 is that it can provide two-way transmission.Therefore, image can be downloaded, be handled by principal computer 120, and can be uploaded to image processor 330 afterwards.Image processor 330 can will be uploaded image decompressor.The image of uploading can be stored in the non-volatile impact damper 360, is stored in the mass storage device, and via after radio-frequency module 355 decompressions, outputs to image decoder 370 via V-bus, or directly output to LCD display.Same, change the command/instruction of compression or, can be uploaded from principal computer 120 in order to image processor 330 via USB hub in order to the orders and instructions of the circuit of control breakout box 300.Being sent to the data of uploading (as portrait or command/instruction) of image processor 330 from principal computer 120, is to be sent to the data download of principal computer 120 (as compressing portrait) from image processor 330 via USB hub.
Except that above-mentioned still image catch get with compress, image processor 330 also has the catching of dynamic image of execution and gets, and according to as H.261, H.262, H.263, MPEG, MPEG-2, motion JPEG etc. are one group of ability that the compression standard specification is compressed immediately wherein.By diagram, can by through USB hub from principal computer 120 or from the received order of non-volatile impact damper 360, select or the encoding compression standard parameter under it or extra coding techniques.Above-mentioned still image program is revised via many images of acquisition and compression one sequence.If image processor 330 can't with the full frame speed of input dynamic menu signal compress with and/or export a compression dynamic menu signal, it also might be opened compressed image from a sequence N and only captures one and come out, wherein N is the integer greater than 1.The dynamic menu signal of output can output to identical device as still image, that is outputs to image decoder 370 (after decompression), frame buffer 350, non-volatile impact damper 360, radio-frequency module 355, and USB hub 340.If compression dynamic image picture signal outputs to principal computer 120 via USB hub 340, principal computer 120 can transmit command/instruction and compress the dynamic image picture signal, and handle at principal computer 120, very similar with the tupe of still image basically.
To dynamic menu compression, as according to MPEG, H.263 MPEG-2 waits the storage demand amount to increase dramatically, particularly to entire image chip or many dynamic images of a sequence.The compression dynamic image can as scsi port 380, output to a high frequency range and mass storage device 60 from image processor 330 via interface.For the example of high frequency range and mass storage device 60, can be hard disk (harddisk), read-write CD (read-writable compact disk, CD-R), and read-write video disc (writable digital video disk) etc.Well known, scsi port 380 provides bidirectional information to transmit, therefore compression dynamically (or static) portrait and (or) instructions/commands also can get back to image processor 330 through scsi port 380 from mass storage device 60.
Image decoder 370 receives from the dynamic image of traffic pilot 310 outputs or from the decompression of image processor 330 outputs and draws a portrait.Image decoder 370 comprises a digital analog converter, becomes analog form in order to converting digital portrait signal.Simulation portrait signal is converted into appropriate signals M, Q, and I and appropriate control signals (as level and vertical marker marker signal) are inserted among the signal M.Signal M combines after the Q, I and produces a composite picture signal, and it can be NTSC, the form of specifications such as PAL.
