Snapping pictures or videos throughout the day has become a lifestyle and are not just for special events any more. Whip out your mobile camera in front of a delectable-looking meal, to record your latest dance moves, or when you just feel like you’re having a good hair day, and you’re ready to share your images with friends. These changes have become possible with remarkable advancements in recent mobile photography and at the very heart of the revolution are the mobile chips that transform light into digital data.
The image sensors we perceive the world through, our eyes, are said to be about 500-megapixels. Compared to most DSLR cameras today featuring 40Mp and flagship smartphones at 12Mp, we as an industry still have a long way to go.
Simply putting as many pixels as possible together might seem to be an easy fix. But that would result in a massive image sensor taking over the device itself. In order to fit millions of pixels in today’s smartphones with bleeding-edge specs such as higher screen-to-body ratios and slimmer designs, pixels had to inevitably shrink for even more compact sensors.
On the other hand, smaller pixels could mean fuzzy or dull pictures, due to the smaller area that each pixel receives light information from. The dilemma between the number of pixels and their sizes becomes a balancing act that requires solid technological prowess.
