Embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done further explain.
Embodiment one
Present embodiment provides a kind of intelligent digital high-definition camera, and this video camera adopts dual-cpu structure, and concrete structure is as shown in Figure 1, comprises housing inner lens 1, imageing sensor 2, graphics processing unit 3 (comprising that people's face detects and recognition of face).Said housing inner lens 1 links to each other with imageing sensor 2, and imageing sensor 2 links to each other with graphics processing unit 3, and graphics processing unit 3 is provided with HD-SDI video interface, ethernet communication interface, USB interface, RS232 interface, RS485 interface etc.
[housing inner lens 1]
The shell of said housing inner lens 1 is provided with the infrared LED light source, even make imageing sensor 2 under the very dark situation of light, also can capture distinct image.
[imageing sensor 2]
The yuv data of imageing sensor 2 outputs directly gets into graphics processing unit 3.Imageing sensor 2 is important component parts of forming digital camera; Difference according to element can be divided into CCD (Charge Coupled Device; Charge coupled cell) and big type of CMOS (Complementary Metal-Oxide Semiconductor, metal oxide semiconductor device) two.
Ccd image sensor is divided into line style (Linear) and two kinds on face type (Area), and wherein line style is applied on image scanning device and the facsimile machine, and the face type is mainly used in digital camera (DSC), takes the photograph on multinomial image input such as video recorder, the monitoring camera product.
Cmos image sensor is divided into passive type element sensor PPSC (Passive Pixel Sensor CMOS) and active pixel sensor APSC (Active Pixel Sensor CMOS).The sharpest edges of cmos image sensor are that it has the condition that height system is integrated.
[graphics processing unit 3]
As shown in Figure 2, said graphics processing unit 3 comprises host CPU 31 and from CPU 32.Said host CPU 31 links to each other with imageing sensor 2, detects in order to image is carried out people's face; Saidly link to each other with host CPU 31, in order to image is carried out recognition of face from CPU 32.Said host CPU 31 is connected with first memory module 33, is connected with second memory module 34 from CPU 32.The yuv data of imageing sensor output directly gets into graphics processing unit (DM368+SDRAM+FLASH, DM6437+SDRAM+FLASH), and the host CPU testing result is kept in first memory module, is kept at second memory module from the recognition result of CPU.
Said first memory module 33 and second memory module 34 be synchronous DRAM (Synchronous Dynamic Random Access Memory, SDRAM).SDRAM adopts the 3.3v operating voltage, 64 of bandwidth, SDRAM locks together with RAM CPU through an identical clock, make RAM and CPU can share a clock cycle, with identical speed synchronization work, with the EDO internal memory mutually specific rate can improve 50%.SDRAM is based on two bank structure; Include two staggered storage arrays, as CPU during from a memory bank or array accesses data, another is just got ready for reading and writing data; Through the tight switching of these two storage arrays, reading efficiency just can be increased exponentially.SDRAM not only can be used as main memory, also is widely used aspect the video memory on display card.
Host CPU is provided with USB+RS232+RS485+ENET communication interface, video output interface CVBS+SDI simultaneously; Microphone interface (being used for simple command recognition), horn interface (being used for voice suggestion), infrared remote control input interface, relay output interface etc. conveniently are directly installed on any places that needs intelligent monitor system such as needing unattended machine room, transformer station, mobile communication base station.
The described intelligent digital high-definition camera of the utility model adopts the dual-cpu structure processor, and processing speed is fast, compact conformation, and rich interface, cost is low, installs, safeguards easy to use.
Embodiment two
The difference of present embodiment and embodiment one is that said first memory module 33 and second memory module 34 are nand flash memory, and nand flash memory array is divided into the block (block) of a series of 128kB, and these blocks are entities wiped minimum in the nand flash memory.Wiping a block is exactly to be set to " 1 " (and all bytes (byte) are set to FFh) to all positions (bit).Be necessary through programming, the position of having wiped is become " 0 " from " 1 ".Minimum programming entity is byte (byte).
The efficient of nand flash memory is higher, is because do not have hard contact in the NAND string.Nand flash memory and hard disk drive are similar, based on sector (page or leaf), are suitable for storing continuous data, like picture, audio frequency or PC data.Though through can be to the RAM in system-level realization arbitrary access data map,, doing like this needs extra RAM memory space.In addition, the same with hard disk, there is bad sector in nand flash memory, needs error correcting code (ECC) to keep the integrality of data.The memory cell area of nand flash memory is more little, and the area of nude film is also just more little.In this case, nand flash memory just can provide memory capacity bigger flash memory products for current low-cost consumption market.Nand flash memory is used for nearly all erasable storage card.The multiplex interface of NAND all provides a kind of similar pin output for all up-to-date devices and density.This pin output makes the design engineer need not change the hardware designs of circuit board, just can be transplanted in the design of bigger density from littler density.
Description of the utility model and application are illustrative, are not to want the scope of the utility model is limited in the above-described embodiments.Here the distortion of the embodiment that is disclosed and change are possible, and the replacement of embodiment is known with the various parts of equivalence for those those of ordinary skill in the art.Those skilled in the art are noted that under the situation of spirit that does not break away from the utility model or substantive characteristics, and the utility model can be with other forms, structure, layout, ratio, and realize with other elements, material and parts.
