HTC M7 Rumored to Come with "Ultrapixels"
A day after HTC's rumored to come up with two more new phones, rumor has it that their upcoming flagship HTC M7 device will be using more impressive camera technology with "ultrapixels". The current top-end smartphones have gradually move up from 8-megapixels to 13-megapixels, and this move to stand out from the rest of the crowd might bring back its former glory. GSMArena has given us a concise breakdown on what "ultrapixels" really mean.
GSMArena.com - "Traditional sensors use a Bayer filter, so each pixels captures only a single color. This means a 13MP photo shot with a traditional sensor has 6.5 million green pixels and 3.25 million of red and blue each. The final image has three colors per pixels, but the missing values are interpolated (math is used to calculate their approximate values).
The HTC M7 sensor will have three layers of pixels stacked on top of each other, each layer capturing one of the three primary colors. Each of the three layers has 4.3 million pixels. So, each ultrapixel will combine real readings from the three layers.
This is somewhat similar to what Nokia did with PureView Phase 1 (the Nokia 808) - the sensor there still uses a Bayer matrix, but thanks to the huge resolution of the sensor, each pixel in the final image is the result of “super sampling” several sensor pixels (so you get at least one real color reading per pixel)."
Nonetheless, we are taking this rumor with a pinch of salt, given how much it will deviate from traditional phone cameras. Moreover, a recently published infographic on camera technology by HTC has hinted at something new, and may very well point to this. Nonetheless, we'll see on the 19th.
