    jinsi hiyo namba inavyokuwa kubwa ndivyo ubora wa picha unavyoongezeka..
    hivyo 6 mega inatoa picha bora zaidi ya 4 mega n.k

    Yap ni kweli mkuu megapixel kubwa si factor pekee itakayodetermine ubora wa camera japo ndio factor kubwa.

    Mfano camera ya 12mp ila ina flash mbovu itachukuaje picha nzuri usiku?

    Camera nyengine inaweza kua auto focus icadectect hichi nini na hichi nini kuboresha ubora wa picha.

    Nyengine zina zoom vizuri kiasi kwamba hata mdudu mdogo anaonekana vizuri

    So muunganiko wa factor nyingi hudetermine quality ya camera ya simu

    [​IMG]

    Picha ya juu hapo imechukuliwa na nokia 808 pureview 41 megapixel best technology kwa camera za simu kwa sasa.

    Megapixel inaifanya hio picha iweze kua nzuri hata kama itatolewa kwenye copy kubwa mfano wanatengeneza tangazo na picha inakua printed kwenye karatasi ya A3. Kitu kama hicho hakiwezi fanywa na camera ya 2mp

    Autofocus- imefanya maeneo muhimu (mdudu) yaonekane vizuri kuliko maeneo yasiyo muhimu (ardhi)

    Zoom- japo hiko kimdudu ni kidogo kimeonekana kwa quality kubwa kama vile ni mkubwa na yeye

    Pixels ni dots zinazotengeneza picha yoyote digital, kwa mfano ukizoom in sana kwenye picha utaanza kuziona square dots hizo ndo pixels, kwa hiyo kamera ya megapixels 6 inakamata doti millioni 6.

    Lakini ubora wa camera hautokani na wingi wa doti tu, kuna mambo mengi ya kuzingatia, kama quality ya lens, size ya sensor inayokamata mwanga etc, ndo maana camera nyingi za digital hata zile simple kabisa bado zinazifunika simu kwa sababu zina nafasi ya kuweka lenzi bora na sensors bora.

    Megapixel nyingi zitasaidia kama unataka kuiprint picha katika size kubwa au unataka ku zoom in kwenye picha, so really ukishaanza kuingia kwenye 5 MP na kwenda juu unless unataka kuprint hizo picha kwenye size kubwa ni waste of space tu.
