Lub ntiaj teb shutter hom yog qhov zoo sib xws "snapshot" raug hom, uas txhais tau hais tias tag nrho cov pixels raug nyob rau tib lub sij hawm, yog li nws muaj peev xwm "khov" kom ntes ceev - txav los yog ceev - hloov cov xwm txheej. Nws yog dav siv nyob rau hauv high - ceev daim ntawv tso cai daim ntawv ntes, nyob kis las kis las thiab lwm yam kev siv.
Ntiaj teb shutter (B) piv rau dov shutter (A)

Qhov zoo ntawm lub ntiaj teb shutter sensors:
?Nce tus nqi
Crystal - ntshiab dluab, txawm rau luv heev exposures
Cov yam ntxwv ntawm lub suab nrov, txawm nyob rau hauv cov teeb pom kev tsis zoo
