Feem ntau, cov tub txawg ntawm cov chaw soj ntsuam cov koob yees duab siv 420 kab, 480 kab, 520 kab, thiab lwm yam los sawv cev rau qhov pom tseeb ntawm lub koob yees duab, uas yog, cov naj npawb ntawm cov kab thaij duab tau tav toj ntawm lub ntsuas. Cov pixels hauv cov tub lag luam lub qhov ncauj feem ntau yog exaggerated, yog li xaiv lub koob yees duab keb soj ntsuam tsis yog ntsuas los ntawm pixels.
Raws li kev piav qhia ntawm tus kws tshaj lij, cov koob yees duab kev soj ntsuam li ib txwm muaj tsuas yog ob theem, nrog kev daws teeb meem tsawg ntawm li 330 kab thiab qhov kev daws teeb meem siab txog li 480 kab. Lub 420 kab cim los ntawm ntau cov lag luam hauv tsev yog qhov tseeb 330 kab khoom. Yav dhau los, tib neeg feem ntau xa mus rau 480-lub koob yees duab ua lub koob yees duab siab txhais. Nrog kev txhim kho ntawm cov thev naus laus zis ntau lawm, DSP siab dhau cov ntxaij lim dej nrog cov txheej txheem ua haujlwm ntawm 7MH ua rau cov kab rov tav daws tau ncav cuag li 520 kab, yog li txuas ntxiv HD soj ntsuam lub koob yees duab cov khoom lag luam tawm. Tab sis hauv qhov tseem ceeb, nws tsuas yog muaj kev txwv txhim kho ntawm lub koob yees duab kev soj ntsuam cov koob yees duab raws li DSP uas twb muaj lawm thiab kev tsim thev naus laus zis, uas tau nce cov tsoos 480-kab HD txheem rau 520 kab lossis 540 kab. Lub koob yees duab tiag tiag pom meej qhov ua tau zoo, ntxiv rau CCD kev ntsuas tau siv, rov qab lub teeb liab ua lub thev naus laus zis xws li nqe lauj Circuit Court, sib piv, xim rov qab, teeb liab-rau-suab sib piv, xaiv lub lens, tseeb tsom thiab lwm yam tuaj yeem cuam tshuam Cov duab khov kho ntawm daim duab.
