Kab rov tav clarity ntawm lub koob yees duab

Vertical clarity ntawm 450 TV cable (tsis muaj EVS)
530 TV cable (nrog EVS)
EVS Vertical Clarity Enhancement System
Qhov ntsuas no kuj yog ib qho tseem ceeb qhia txog lub koob yees duab zoo.
Lub zog decomposition ntawm yav dhau los lub koob yees duab raj yog qhov siab, tab sis lub zog decomposition ntawm CCD chips kuj tau zoo heev, yuav luag tag hloov lub koob yees duab raj.
Geometric distortion:
Zoo li lub geometric distortion ntawm TV, cov koob yees duab kuj muaj geometric distortion, uas yog tshwm sim los ntawm lub optical system ntawm lub lens thiab scanning thiab deflection Circuit Court ntawm lub koob yees duab raj. Rau CCD, yog tias lub lens distortion tsis tau txiav txim siab, tsis muaj geometric distortion nws tus kheej. (Cov ntsuas dav dav qhia: geometric distortion: hauv qab ntsuas ntsuas)
Geometric distortion yog qhia raws li feem pua ​​ntawm distortion offset rau qhov siab qhov screen. Feem ntau, tag nrho cheeb tsam ntawm peb cov kav dej yuav tsum yog ntau tshaj 1%, nrog rau ntau hom kev sib txawv ntawm geometric distortion thiab kev faib hauv cheeb tsam.
