Apple Inc.’s next-generation iPhone model, dubbed the “iPhone 6S,” could feature a 12-megapixel Sony camera, Japanese media reported Monday. The new camera is expected to use Sony’s RGBW technology to capture better photos in low-light conditions.

The upcoming model, which is yet to be formally named by the Cupertino-based firm, is not likely to sport a dual-camera setup with wide-angle and telephoto lenses as some earlier reports had suggested, Apple Insider reported, citing Feng.com, a Japanese technology news website. The report also stated that the inclusion of the RGBW technology would be a definite plus for low-light imaging.

The existing iPhone 6 and iPhone 6 Plus both include 8-megapixel camera sensors with 3264x2448 pixels designed to improve light sensitivity. According to Feng.com, the new Sony-made camera with RGBW technology would employ an extra white subpixel to serve a similar purpose.

The report also stated that Apple initially planned to use RGBW in the iPhone 6 and iPhone 6 Plus. However, it eventually decided to wait to ensure that the technology met higher quality standards before using it in its products.

This is not the first time that the new iPhone is speculated to feature a higher megapixel camera. IHS China CEO Kevin Wong recently said that Apple’s anticipated iPhone 6S could sport a 12-megapixel camera for better low-light images with less “noise.”

The next iPhone is also rumored to be available in 4.7- and 5.5-inch versions, with several new features, including support for Force Touch, a pressure-sensitive control system introduced with the Apple Watch, Apple Insider reported.

According to rumors, the iPhone 6S could be available in 32GB, 64GB and 128GB options, killing off the 16GB version.
