Wane ne bayanan piksel na kameran?
Modulun kameran da 5MP ko 8MP zai zama abin da ke dace sosai saboda yadda ake fahimta da alama mai gaba:
- Hoton da ke zama mai kyau;
- Kyakkyawan yadda ake gano abin da ke aiki;
Don kuma, many security systems, embedded devices, da industrial vision applications suna so su amfani da high-resolution camera modules. Amma, wadannan cameras suna gaskiya da wasu abubuwa da ba su dace ba a lokacin yamma. A lokacin da kasa ta zama mai tsoro na light, kamar yadda ake fassara, kuma kuma yin amfani da number of pixels ba zai iya nuna final image quality ba. Size of the sensor, size of the pixel, da dynamic range suna iya gyara actual imaging effect. High-pixel camera tana yi kyau a rana, amma a lokacin da kasa ta zama mai tsoro, sensor ya sami less light saboda yadda ya zama mai tsoro na light information da ya iya samun.
Matsalolin da yawa su ne:
- Reduced details in dark areas;
- Reduced visibility in complex environments;
Wannan kuma ya zama cause of important theory:
More pixels do not mean better night vision effect
A low-light scenarios, engineers su koyi da mahaillinsu abubuwan da suka fiye da resolution:
- Low-light imaging capability;
- Sensor light-sensing ability;
- Tsarin saukarwa ta hanyar bayanin taswira;
