Menene Yawo a HD?
Kalmar HD tana nufin Babban Ma'ana, kuma HD Streaming tana nufin ingancin ƙudurin bidiyo na HD da ake yaɗawa ta intanet don kunnawa. Ana iya yin hakan ta amfani da tsare-tsare daban-daban na bidiyo, ciki har da MPEG ko kuma yaɗa bidiyo mai santsi.
Abubuwan da ke cikin bidiyo na HD za su ba ku haske da cikakken bayani fiye da ƙudurin bidiyon SD, wanda galibi ana gani a YouTube da sauran gidajen yanar gizo. Za ku ga ƙarancin pixelation a cikin abun ciki mai girma saboda yana da pixels sau biyu a kowane firam (1920 × 1080) fiye da bidiyon ma'auni na yau da kullun a 1280 × 720. Waɗannan hotuna masu inganci kuma suna da ingantaccen sake fasalin launi da motsi mai santsi saboda saurin firam ɗin su.
ƙudurin bidiyo a tsaye
1.SD tsarin bidiyo ne mai ƙudurin zahiri ƙasa da 720p (1280*720). 720p yana nufin ƙudurin tsaye na bidiyon shine layuka 720 na duba ci gaba. Musamman ma, yana nufin tsarin bidiyo "ma'aunin ma'auni" kamar shirye-shiryen VCD, DVD, da TV tare da ƙudurin layuka kusan 400, wato, ma'aunin ma'auni.
2.Idan ƙudurin zahiri ya kai 720p ko sama da haka, ana kiransa da babban ma'anar (ma'anar Turanci Babban Ma'anar) wanda ake kira HD. Dangane da manyan ma'auni, akwai guda biyu da aka sani a duniya: ƙudurin tsaye na bidiyo ya wuce 720p ko 1080p; rabon ɓangaren bidiyo shine 16:9.
Bidiyon High Definition (HD) ba sabon abu bane a duniyar kayan lantarki na masu amfani inda aka sami babban sauyi daga Standard Definition (SD) zuwa HD mai ban sha'awa sosai.
A fannin duba masana'antu, sauyin ya yi jinkiri amma duk da haka, ba makawa ne. Duk da cewa yawancin tsarin dubawa da kyamarorin da ake da su a kasuwa har yanzu suna da Ma'anar Daidaito, masana sun yi hasashen cewa HD zai zama babbar fasahar nan da shekarar 2020.
Hotunan launi sun ƙunshi ƙananan ɗigogi da ake kira pixels, tare da ƙuduri yana nufin jimlar adadin pixels a cikin bidiyo ko hoto. Ma'anar bidiyon SD yana farawa daga 240p kuma yana ƙarewa a 480p, yayin da ƙudurin 1080p shine cikakken ƙarfi HD (tare da duk abin da ke sama da wannan ana ɗaukarsa Ultra-HD).
Ƙarin bayani:
Yadda kyamarar ke aiki:
1. Kyamarar ta ƙunshi ruwan tabarau, mai riƙe da ruwan tabarau, capacitor, resistor, infrared filter (IP Filter), firikwensin (Firikwensin), da'ira, guntu mai sarrafa hoto DSP da allon ƙarfafawa da sauran abubuwan haɗin gwiwa.
2. Akwai nau'ikan na'urori masu auna sigina guda biyu, ɗaya shine na'urar auna sigina mai haɗa chaji (CCD) ɗayan kuma shine na'urar auna sigina mai auna sigina mai auna sigina na ƙarfe (CMOS); allon da'ira galibi allunan da'ira ne da aka buga (PCB) ko kuma allunan da'ira masu sassauƙa (FPC).
3. Hasken wurin yana shiga kyamara ta cikin ruwan tabarau, sannan yana tace hasken infrared da ke cikin hasken da ke shiga ruwan tabarau ta hanyar matatar IR, sannan ya isa ga firikwensin (firikwensin), wanda ke mayar da siginar gani zuwa siginar lantarki.
4. Ta hanyar na'urar canza analog/dijital ta ciki (ADC), ana mayar da siginar lantarki zuwa siginar dijital, sannan a aika ta zuwa guntu mai sarrafa hoto DSP don sarrafawa, sannan a mayar da ita zuwa RGB, YUV da sauran tsare-tsare don fitarwa.
