"According to the patent, the digital cameras found in most smartphones have a single light sensor. That has a color filter split between red, blue and green colors, laid in a grid on top. Once an image is captured by the light sensor, it has to reconstruct the image based on the samples of color from the filter with a process called demosaicing. This tends to lead to images that are blurrier than real life, as the light sensor can only pick up colors where they are in a grid."
"Apple’s new idea: Using a cube of triangular prisms, light is split out into green, red and blue streams, which are each picked up by an independent sensor. This would mean images would be truer to life in color and resolution. It could also mean that photos taken in low-light situations (indoors, at night, etc.) would actually be clearer."
