The camera module sensor is placed vertically within the phone and aimed at a lens with an optical axis that runs along the body of the phone. A mirror or prism is placed at the correct angle to reflect light from the scene into the lens and sensor.
Why do cameras have multiple lens?
This is done to reduce the effects of chromatic aberration, which results in blurring because different light colors end up being focused at different points due to the dependence of the refraction process on the frequency of the light. A Double Gauss has two lens groups and 7 lenses.
How does the triple camera work?
The monochrome sensor
In some triple camera cases, the additional camera is used to improve photography in low light conditions. Putting in a monochrome sensor makes cameras more sensitive to light. They are better to detect contrast and differentiate between different gradients of light and dark.
Why do phones have multiple lenses?
Both these smartphones (and there were some others) used dual lenses to allow them to take 3D video and 3D photos. They use the same technique used by regular 3D cameras, using those dual lenses to create a sense of depth in images. This was boosted with a 3D display to view those images, without the glasses.
What is a multi lens?

What are the disadvantages of multifocal lenses?
Cons of multifocal IOLs
- Difficulty seeing at a close distance: While this is rare, sometimes, patients may require reading glasses. This depends on their existing prescription and eye health before surgery.
- Night vision, halos, or glares: Only about 1% of our patients develop halos and glares on lights after dark.
How long does it take to get used to multifocal lens implants?
It may take them three days, three months or six months to adjust and learn how to adapt to their new vision. Some patients may not ever adapt and, for them, we should be ready to exchange a multifocal or EDOF lens for a monofocal IOL.
How long do multifocal lenses last?
Multifocal lens cataract surgery
Unlike multifocal contact lenses, they don’t need regular care or replacement, they last forever! Many patients who have multifocal IOLs find that they don’t need to wear glasses after cataract surgery, or if they do, they may only need reading glasses for fine print.
How do dual cameras work on phones?
A dual camera offers two photo sensors instead of the standard one photosensor.The second camera works to add more elements that the main sensor can’t do on its own. It can offer additional zoom power, boost the clarity of photos, and help capture wide-angle photos.
