Module ya kamera ya DVP VS MPI

Mawu Oyamba

Kamera wamba pa mafoni am'manja ndi MIPI, ndipo makamera ena (monga zida zina zomwe zimathandizira mawonekedwe a DVP) ndi DVP.

MIPI ndichidule cha Mobile Industry Processor Interface (Mwachidule, USB imayimira Universal Serial Bus, MIPI imayimira Mobile Industry Processor Interface, DVP imayimira doko la kanema wa digito, ndipo CSI imayimira CMOS Sensor Interface.

1.DVP mawonekedwe

DVP basi PCLK malire pafupifupi 96M, ndipo kutalika kwa mzere sikungakhale motalika kwambiri, mlingo waukulu wa DVP onse umayendetsedwa bwino pansi pa 72M, PCB masanjidwe osavuta kujambula.

DVP ndi doko lofanana ndipo imafuna PCLK, VSYNC, HSYNC, D[0:11] - ikhoza kukhala 8/10/12bit data, kutengera ISP kapena thandizo la baseband

Gawo lotulutsa la DVP: VSYNC (chizindikiro cholumikizira chimango), HSYNC (chizindikiro cholumikizira mzere), PCLK (wotchi ya pixel), mzere wa data (8-bit kapena 10-bit) - data yoyambirira ya RGB yotumizidwa

2.MIPI mawonekedwe

MIPI ndi kufala kosiyana kwa doko, kuthamanga, kutsutsa kusokoneza.Ma module apamwamba a foni yam'manja tsopano akugwiritsa ntchito kutumiza kwa MIPI.

Kamera ya MIPI ili ndi mphamvu zitatu: VDDIO (IO mphamvu), AVDD (mphamvu yaanalogi), DVDD (kernel digital power), magetsi osiyana a sensor module kamera ndi osiyana, AVDD ili ndi 2.8V kapena 3.3V;DVDD nthawi zambiri imagwiritsa ntchito 1.5V kapena kupitilira apo, kapangidwe ka opanga osiyanasiyana ndi kosiyana.

Zowonjezerapo: mawonekedwe a kamera a MIPI amatchedwa CSI, ndipo mawonekedwe a MIPI amatchedwa DSI.

Mawonekedwe a mawonekedwe a CSI-2 amatulutsidwa ndi bungwe la MIPI (Mobile Industry Processor Interface) pamawonekedwe amtundu wa kamera.

Mawonekedwe a MIPI CSI-2 amagwiritsa ntchito zinthu zochepa kuchokera ku CPU - chifukwa cha mapurosesa ake ambiri.Ndilo mawonekedwe a kamera a Raspberry Pi ndi Jetson Nano.Raspberry Pi kamera ya V1 ndi V2 imakhazikitsidwanso.

MIPI ndi muyezo wotseguka wa ma processor a mafoni oyambitsidwa ndi MIPI Alliance, ndipo protocol ya MIPI-CSI-2 ndi gawo laling'ono la protocol ya MIPI Alliance, yomwe idapangidwira mwapadera mawonekedwe a chipangizo cha kamera.

Ronghua, ndi wopanga okhazikika mu R&D, makonda, kupanga, kugulitsa ndi ntchito zama module a kamera, USB DVP.

ndi ma module a kamera a MIPI, magalasi ndi zinthu zina.Ngati mukufuna lemberani, chonde:
