Imodyuli yekhamera ye-DVP VS MIPI

Intshayelelo

Ikhamera eqhelekileyo kwii-smartphones yi-MIPI, kwaye ezinye zeekhamera (ezifana ne-hardware ethile exhasa i-DVP interface) yi-DVP.

I-MIPI imfutshane kwiMobile Industry Processor Interface (Ngokufutshane, i-USB imele iUniversal Serial Bus, iMIPI imele iMobile Industry Processor Interface, iDVP imele izibuko levidiyo yedijithali, kwaye iCSI imele iCMOS Sensor Interface.

I-interface ye-1.DVP

I-DVP ibhasi ye-PCLK umda malunga ne-96M, kwaye ubude bomgca abukwazi ukuba bude kakhulu, izinga eliphezulu le-DVP lilawulwa kakuhle ngaphantsi kwe-72M, i-PCB layout lula ukuyitsala.

I-DVP yi-port ehambelanayo kwaye ifuna i-PCLK, i-VSYNC, i-HSYNC, i-D [0: 11] - ingaba yi-8/10/12bit data, kuxhomekeke kwi-ISP okanye inkxaso ye-baseband.

Inxalenye yemveliso ye-DVP: I-VSYNC (isignali yokuvumelanisa isakhelo), i-HSYNC (isignali yokuvumelanisa umgca), i-PCLK (iwotshi yepixel), umgca wedatha (i-8-bit okanye i-10-bit) - idatha ye-RGB yokuqala

2.MIPI interface

I-MIPI yi-different serial port transmission, isantya esikhawulezayo, anti-interference.Iimodyuli zeselfowuni eziphambili ngoku zisebenzisa ukuhanjiswa kwe-MIPI.

Ikhamera ye-MIPI inezixhobo ezintathu zamandla: i-VDDIO (i-IO amandla), i-AVDD (amandla e-analog), i-DVDD (amandla edijithali ye-kernel), imodyuli yemodyuli eyahlukileyo unikezelo lwamandla ekhamera luhlukile, i-AVDD ine-2.8V okanye i-3.3V;I-DVDD isebenzisa ngokubanzi i-1.5V okanye ngaphezulu, uyilo lwabavelisi abahlukeneyo bahlukile.

Inqaku elongezelelweyo: I-interface yekhamera ye-MIPI ibizwa ngokuba yi-CSI, kwaye i-interface ye-MIPI yokubonisa ibizwa ngokuba yi-DSI.

Inkcazo ye-interface ye-CSI-2 ikhutshwe yi-MIPI (I-Mobile Industry Processor Interface) umbutho we-Alliance kwi-interface yochungechunge lwekhamera.

I-interface ye-MIPI CSI-2 isebenzisa izixhobo ezimbalwa ezivela kwi-CPU - enkosi kwiiprosesa zayo ezininzi.Lujongano lwekhamera olungagqibekanga lweRaspberry Pi kunye neJetson Nano.Imodyuli yekhamera yeRaspberry Pi iV1 kunye neV2 nayo isekwe kuyo.

I-MIPI ngumgangatho ovulekileyo wabaqhubekekisi besicelo sefowuni eqalwe yi-MIPI Alliance, kwaye i-MIPI-CSI-2 protocol yiprotocol ephantsi ye-MIPI Alliance protocol, eyilelwe ngokukodwa ujongano lwechip yekhamera.

I-Ronghua, ngumenzi okhethekileyo kwi-R & D, ukwenza ngokwezifiso, ukuveliswa, ukuthengisa kunye nenkonzo yeemodyuli zekhamera, i-USB DVP

kunye neemodyuli zekhamera ye-MIPI, iilensi kunye nezinye iimveliso.Ukuba unomdla wokuqhagamshelana nathi, nceda:
