Okwu mmalite
Igwefoto a na-ahụkarị na smartphones bụ MIPI, yana ụfọdụ igwefoto (dị ka ụfọdụ ngwaike na-akwado interface DVP) bụ DVP.
MIPI dị mkpụmkpụ maka Interface Onye nrụpụta ụlọ ọrụ Mobile (Na nkenke, USB na-anọchi anya Universal Serial Bus, MIPI na-anọchite anya Interface Industry Industry Processor, DVP na-anọchi anya ọdụ ụgbọ mmiri vidiyo dijitalụ, na CSI na-anọchi anya CMOS Sensor Interface.
1.DVP interface
DVP ụgbọ ala PCLK ịgba nke banyere 96M, na ogologo nke ahịrị enweghị ike ịdị ogologo, kacha ọnụego nke niile DVP kasị mma na-achịkwa n'okpuru 72M, PCB okirikiri nhọrọ ukwuu mfe ise.
DVP bụ ọdụ ụgbọ mmiri yiri ya ma chọọ PCLK, VSYNC, HSYNC, D[0:11] - nwere ike ịbụ data 8/10/12bit, dabere na ISP ma ọ bụ nkwado baseband.
Akụkụ mmepụta DVP: VSYNC (akara ngosi mmekọrịta etiti), HSYNC (akara ngosi akara), PCLK (elekere pixel), ahịrị data (8-bit ma ọ bụ 10-bit) - data RGB mbụ bufere
2.MIPI interface
MIPI bụ nnyefe ọdụ ụgbọ mmiri dị iche iche, ọsọ ọsọ, mgbochi nnyonye anya.Modul ekwentị ekwe ntị na-eji nnyefe MIPI ugbu a.
Igwefoto MIPI nwere ike inye ọkụ atọ: VDDIO (ike IO), AVDD (ike analog), DVDD (ike dijitalụ kernel), ike ọkọnọ igwefoto sensọ dị iche iche, AVDD nwere 2.8V ma ọ bụ 3.3V;DVDD n'ozuzu na-eji 1.5V ma ọ bụ karịa, dị iche iche emepụta' imewe dị iche iche.
Ihe mgbakwunye: MIPI igwefoto interface ka a na-akpọ CSI, na MIPI ngosi interface ka a na-akpọ DSI.
Ndị MIPI (Mobile Industry Processor Interface) Alliance wepụtara nkọwapụta nkọwapụta interface CSI-2 na interface serial igwefoto.
MIPI CSI-2 interface na-eji ihe ndị dị ole na ole sitere na CPU - ekele maka ndị na-arụ ọrụ multi-core.Ọ bụ interface igwefoto ndabere maka Raspberry Pi na Jetson Nano.Igwefoto Raspberry Pi V1 na V2 dabere na ya.
MIPI bụ ọkọlọtọ mepere emepe maka ndị nrụpụta ngwa mkpanaka nke MIPI Alliance butere, yana MIPI-CSI-2 protocol bụ sub-protocol nke MIPI Alliance Protocol, nke emebere nke ọma maka interface nke mgbawa igwefoto.
Ronghua, bụ onye nrụpụta ọkachamara na R&D, nhazi, mmepụta, ahịa na ọrụ nke modulu igwefoto, USB DVP.
na modul igwefoto MIPI, lenses na ngwaahịa ndị ọzọ. Ọ bụrụ na ị nwere mmasị ịkpọtụrụ anyị, biko :
