Kungani i-FPS ayiyona indaba yonke
Amakhompiyutha amaningi amasha athumela ngekhamera yewebhu eyakhelwe ngaphakathi kwezokuxhumana kwevidiyo. Amakhompiyutha angenawo amakhamera ewebhu akhakhiwe asekela amakhemikhali ewebhu webcam. Kungenzeka ukuthi usuvele wazi ukuthi izinga eliphakeme le - frame yamakhamera we- webcam yilokho, ujabula ngokwengeziwe ukuthi uzoba nedivaysi yakho, kodwa yiliphi izinga lohlaka futhi kungani udinga ukunaka le namba?
Isilinganiso Sokwakheka?
Kulula nje, isilinganiso sefreyimu yinombolo yezithombe ikhamera yewebhu ithatha futhi idluliselwe esikrinini sekhompuyutha. Amafreyimu alinganiswa ngamafomu ngesigamu. Uma ikhamera yakho yewebhu ichazwa njengama-fps angu-30, ingathatha izithombe ezingu-30 njalo ngomzuzwana bese izidlulisela kwikhompyutha.
Indlela Esebenza ngayo
Uma isithombe (noma ifreyimu) sithunjwe ngekhamera yewebhu ngezinga eliphansi le-fps lama-15 fps noma ngezansi, ikhamera yewebhu ikhiqiza ifayela le-JPEG yesithombe ngasinye namanje futhi idlulisa uchungechunge lwalezi JPEG namanje izithombe. Uma isilinganiso sefreyimu sikhulu kunama-fps angu-15, ikhamera yewebhu impela ifaka ividiyo ngokuxhumeka kwe-intanethi.
Amazinga omumo ngokuvamile avela ku-15 kuya ku-120 fps. Kufanele uhlale ngama-fps angu-30 noma ngaphezulu uma ungafuni ukudlulisa ividiyo ye-choppy. Ukuphakama kwesilinganiso sohlaka, kushisa ividiyo.
Qaphela: Ukuze usakaze ividiyo, awudingi kuphela ikhamera yewebhu ngezinga elihle lokuma, kepha udinga uxhumano lwe-inthanethi eliphezulu.
Izinto ezingaphandle
Nakuba ukulinganisa kwekhamera yewebhu kungabonisa isivinini esisodwa, ikhamera yakho yewebhu ingabamba ngempela ividiyo ngejubane elihlukile. Izici ezithile zithinta isilinganiso sefreyimu yewebhu, njengamakhono weprogram yesofthiwe yewebhu, indaba ozama ukuyibhala, isinqumo sekhamera yewebhu, inani lokukhanya ekamelweni kanye nomkhawulokudonsa okhona . Ukugijima kwamadivaysi amaningi ngaphezu kwamaphakheji e- USB akhompyutheni kunganciphisa izinga lohlaka. Ungakwazi ukwandisa i-fps yakho ye-webcam ngokukhulisa ukukhanyisa ekamelweni bese udibanisa i-hard hard drive yakho.
Ikusasa lama-Webcams
Kuphephile ukusho ukuthi ama-frame rates azoqhubeka nokukhula ngokubambisana nesinqumo sewebhu, esinquma ukuthi ividiyo ibukhali kangakanani. Njengoba amazinga aphezulu ohlaka kanye nezinqumo eziphezulu eziphezulu ziba indawo evamile, amanani azokwehla futhi ama-webcams aphansi wezinga lohlaka azophela. Ngeke kube yisikhathi ngaphambi kokuba ama-fps angu-60 abe amathambo angabonakali ubuncane bekhamera ye-web-entry.
