He maha ngā kāmera kei te mākete e tohua ana ki ngā kāmera whakamārama-teitei, ngā kāmera whakamārama-paerewa,nā reira whe aha te rerekētanga i waenga i ngā kāmera SD me HD? Mā te taumira poutū ataata me te rerekētanga pika, he rerekētanga pika, ā, he kāmera whakamārama-teitei i te 96W me runga ake.
Whakamāramatanga
He aha te Rerema HD?
Ko te kupu HD he tohu mō te Whakamāramatanga Teitei, ā, ko te HD Streaming e pā ana ki te taumira ataata kounga HD e rere ana i runga i te ipurangi hei purei. Ka taea te mahi mā te whakamahi i ngā momo hōputu ataata rerekē, tae atu ki te MPEG, te rere ataata maeneene rānei.
Mā ngā ataata rere HD ka nui ake te māramatanga me te taipitopito i te taumira ataata SD, e kitea pinepine ana i runga i a YouTube me ētahi atu paetukutuku. Ka iti ake te pikinga o ngā pika i roto i ngā ataata whakamārama-teitei nā te mea e rua ngā pika i ia anga (1920×1080) i ngā pikitia whakamārama-paerewa i te 1280×720. He pai ake te whakaputa tae o ēnei pikitia kounga teitei, ā, he maeneene ake te nekehanga nā te tere o te anga.
Taumira poutū ataata
1.He hōputu ataata te SD me te taumira ā-tinana i raro i te 720p (1280*720). Ko te tikanga o te 720p ko te taumira poutū o te ataata he 720 rārangi o te matawai haere whakamua. Ina koa, e pā ana ki ngā hōputu ataata "whakamāramatanga paerewa" pēnei i te VCD, DVD, me ngā hōtaka pouaka whakaata me te taumira o te 400 rārangi, arā, te whakamāramatanga paerewa.
2.Ina tae te taumira ā-tinana ki te 720p, neke atu rānei, ka kiia he whakamāramatanga-teitei (te kupu Ingarihi High Definition) e kiia ana ko HD. Mō ngā paerewa whakamāramatanga-teitei, e rua ngā paerewa e mōhiotia ana i te ao: ko te taumira poutū o te ataata he nui ake i te 720p, 1080p rānei; ko te ōwehenga āhua ataata he 16:9.
Ehara i te mea hou te ataata Whakamāramatanga Teitei (HD) i te ao o ngā taputapu hiko kaihoko, kua nui te nekehanga mai i te Whakamāramatanga Paerewa (SD) ki te HD tino whakamiharo ki te titiro.
I roto i te ao tirotiro ahumahi, kua puhoi ake te whakawhiti engari kāore e taea te karo. Ahakoa ko te nuinga o ngā pūnaha tirotiro me ngā kāmera e wātea ana i te mākete i tēnei wā he Paerewa Whakamāramatanga tonu, e matapaetia ana e ngā tohunga ko te HD te hangarau matua i te tau 2020.
Ko ngā whakaahua tae he mea tito mai i ngā ira iti e kiia nei ko ngā pika, ko te taumira e pā ana ki te tapeke o ngā pika i roto i tētahi ataata, i tētahi whakaahua rānei. Ko te whakamāramatanga mō te ataata SD ka tīmata i te 240p ka mutu i te 480p, ko te taumira 1080p ia he HD kaha-katoa (me ngā mea katoa i runga ake i tēnei ka kiia he Ultra-HD).
Ngā mōhiohio whānui:
Te mahi a te kāmera:
1. Kei roto i te kāmera he arotahi, he pupuri arotahi, he pūnga iahiko, he ātete, he tātari pūwhero-whero (Tātari IP), he pūoko (Pūoko), he papa ara iahiko, he maramara tukatuka whakaahua DSP me te papa whakakaha me ētahi atu wāhanga.
2. E rua ngā momo pūoko, ko tētahi he pūoko hono-utu (CCD) me tētahi he pūoko ara iahiko waikura whakarewa (CMOS); ko ngā papa ara iahiko he papa ara iahiko tānga (PCB) he papa ara iahiko ngāwari rānei (FPC).
3. Ka tomo te mārama tirohanga ki te kāmera mā te arotahi, kātahi ka tātarihia te mārama whero-whero i roto i te mārama e tomo ana ki te arotahi mā te tātari IR, kātahi ka tae atu ki te pūoko (pūoko), ka huri i te tohu whatu hei tohu hiko.
4. Mā te kaitahuri ā-roto o te anaro/matihiko (ADC), ka hurihia te tohu hiko hei tohu matihiko, kātahi ka tukuna ki te maramara tukatuka whakaahua DSP hei tukatuka, ā, ka hurihia hei RGB, YUV me ētahi atu hōputu hei putanga.
