Tab sis es tsis txhob ua yeeb yaj kiab, lub koob yees duab digital siv lub ntsuas qhov muag los ntes cov duab. Cov sensors no yog tsim los ntawm CCD sensors (cov khoom siv sib txuas ua ke) lossis CMOS (cov khoom siv hlau oxide semiconductor ntxiv) sensors. Muaj qee qhov kev txhim kho hnyav thiab qhov zoo ntawm lub koob yees duab digital tshaj li lub koob yees duab raws li lub koob yees duab. Lub sensor tuaj yeem tsim cov duab tsis txwv tsis pub muaj kev hloov pauv. Qhov no txo tus nqi siv.
