Birazwi cyane ko gufata amafoto hafi cyane iyo urumuri rwijimye cyane, uko urumuri ruto rwaba rufite imbaraga zingana kose ndetse n'ubushobozi bwo gufotora urumuri rwijimye bungana kose, nta flash ishobora gufatwa, harimo na SLR. Rero kuri telefoni, byatumye habaho ikoreshwa rya flash ya LED.

Ariko, bitewe n'imbogamizi z'ikoranabuhanga rikoreshwa mu bikoresho, amatara menshi ya LED akoreshwa ubu akozwe mu rumuri rwera + fosforasi, ibyo bikaba bigabanya urwego rwa spectral: ingufu z'urumuri rw'ubururu, ingufu z'urumuri rw'icyatsi n'umutuku ni nto cyane, bityo ikoreshwa. Ibara ry'ifoto yafashwe na LED flash rizahinduka (umweru, ibara rikonje), kandi bitewe n'ubusembwa bwa spectral n'imiterere ya fosforasi, biroroshye gufata amaso atukura no kuyarabagirana, kandi ibara ry'uruhu rirabagirana, bigatuma ifoto iba mbi cyane, ndetse na nyuma yo "guhindura imiterere y'isura" byatinze. Porogaramu nayo iragoye kuyihindura.

Uburyo bwo gukemura telefoni igendanwa igezweho? Muri rusange, igisubizo cya LED gifite ubushyuhe bubiri gikoresha urumuri rwera rwa LED + urumuri rushyushye rw'amabara ya LED ni ukugira igice cy'urumuri rwa LED rubura hakoreshejwe urumuri rw'amabara ashyushye rwa LED, bityo biganisha ku ruhu ruhuye neza na spectrum y'izuba, bingana no kubona urumuri rw'izuba rusanzwe rutuma urumuri rwuzuye rugaragara neza, kandi bikuraho ibara ry'urumuri rusanzwe rwa LED, uruhu rwerurutse, urumuri n'ijisho ritukura.

Birumvikana ko hamwe n’ubuhanga mu ikoranabuhanga, ubwo buryo bwo gupima ubushyuhe bw’amabara abiri bwakoreshejwe cyane kuri telefoni zigezweho, kandi ubwo buryo bwakoreshejwe kuri telefoni zigezweho ku rugero runini.
