Days after buyers of iPhone 5 complained about packaging issue, Apple iPhone 5 is now facing the music for ‘flaws’ in its 8 megapixel iSight camera.
According to some users, there’s a purple haze in the images captured through the 8 megapixel iSight camera of iPhone 5. A thread at AnandTech Forum also points at the purple haze in images which is actually termed as chromatic aberration that usually caused by lens dispersion. In simpler words, the lens fails to focus on all colours traveling at different wavelengths to a same convergence point.
The issue however seems to be limited only to select devices of the iPhone 5.
The new Apple iPhone 5 users an 8 megapixel camera with a lens built using 5-element glass and also includes Sapphire Crystal glass.
The purple flaring issue arises mostly when the iPhone 5 is used towards bright lights, like the Sun, to capture images. The flaring is less with LED lighting or computer monitors. Couple of users managed to test and nail down to the fact that the issue persists in several other iPhone 5 versions from different mobile service providers.
At this moment, it is difficult to determine whether the issue is caused due to 5-element lens entirely or due to the new inclusion of Sapphire Crystal glass in it. Notably, several other mobile phones had in the past also faced the purple flaring issue.
As of now, the only way to avoid the “purple flaring” is to refrain from capturing images towards bright lights.
