The next-generation iPhone will reportedly sport a camera with a 12-megapixel Sony sensor that makes use of the firm's RGBW technology to help with low-light photography.

Sources downplayed the possibility of a dual-camera setup with wide-angle and telephoto lenses, according to Japanese media reports cited by Feng.com, but noted that RGBW means an alleged switch to smaller pixels won't come at the expense of low-light imaging.

The iPhone 6 and 6 Plus both employ 8-megapixel sensors with larger-than-average pixels designed to improve light sensitivity. RGBW makes use of an extra white subpixel to achieve a similar effect.

The reports suggest that Apple originally intended to use RGBW for the iPhone 6 and 6 Plus, but instead opted to wait to make sure its implementation would meet quality standards.
