Dual Camera Mobile me 3 tarah ke combinations kam liye jate hai -

 01  Telephoto + Wide Angle Lens -

Es tarah ke combination me ek camera ka lens Telephoto (Secondary) hota hai or dusra Lens Wide angle (Primary) hota hai. Yah ab tak ka sabse lokpriya (famous) combination hai. Es combination ko Apple, One Plus, Samsung etc mobiles me dekha ja sakata hai.
Telephoto Lens ki focus length jyada hoti hai jisake karan camera Background or Object ( Foreground) ke bich me antar (differentiate) kar pata hai. Eski help se camera photo ko capture karta hai or mobile ka software use blur karta hai. Es effect ko Bokeh Effect kahate hai. Es effect ko aap iphone 8 Plus or Samsung Galaxy Note 8 etc me dekh sakate hai.
En lenses ka use photo ko 2x optical zoom (not digital zoom) karne ke liye bhi hota hai. optical zooming me picture crop nhi hoti hai jisase image ki quality down nhi hoti hai lekin digital zooming me picture crop hoti hai jisase picture ki quality kharab ho jati hai.
Telephoto Lens me aperture kam hone ke karan yah combination kam light me badhiya quality nhi de pata hai lekin fir bhi yah combination background ko blur karne ke purpose se sabse jyada use liya jata hai.
Wide Angle Lense ka use maximum area ko capture karne ke liye kiya jata hai taki jyada se jyada se elements camera ki frame me aa sake.

Positive points -


  • 2x optical zooming.
  • Bokeh Effect.

Negative points -

  • Low optical zooming.
  • Bokeh effect low light me work nhi karta hai.
  • 2x optical zooming har bar kaam nhi aati hai.

 02  RGB + Monochrome -

Yah Combination sabse pahale Huawei ne apne mobile Honor 6 Plus me use liya tha. Es combination me ek monochrome sensor or ek RGB  sensor use liya jata hai. Monochrome sensor only Black & White image capture karta hai or RGB sensor Color image capture karta hai. Esliye Monochrome sensor ka use only light capture karne ke liye hota hai. Es light ko RGB sensor se capture ki gai image ke sath me mix kar diya jata hai jisase picture me brightness badh jati hai. Jisase final image me color ki quality kafi badhiya aati hai.
Es combination me yah jaroori hota hai ki dono cameras same resolution ke ho kyonki dono cameras se li gai pictures ko combine karke final picture create ki jati hai.

Positive points -

  • Brighter Color
  • Better Color
  • Capture Monochrome image

Negative points -

  • Bokeh Effect proper work nhi karta hai.
  • Same Resolution ke sensors ki jaroorat hoti hai.

 03  Wide angle + Regular-

Dual Mobile Camera ke es combination ko LG ne LG G5 or LG G6 me use kiya tha. Wide angle (Secondary) lens ko use lene se final image me fish eye lens ka effect aata hai. Yah camera maximum area ko capture kar sakata hai. Es combination me dono lenses same resolution ke hote hai. Esme picture linear ki jagah spherical shape me capture hoti hai.

Positive points -

  • Fish Eye lens Effect

Negative points -

  • Primary or secondary lens ka resolution ka same hona jaroori hai.
  • Barrel Distortion.
