One of the highlight features of the new Moto X is the 'Clear Pixel' technology used by its camera.  But just what is it and how is it different from ordinary phone cameras?   Well just like clockwork, Omnivision has issued a press release announcing the availability of their new 10.5 Megapixel RGBC Camera Solution, which just so happens to be the very sensor that Motorola is using inside the Moto X.  Now you can read the tech details to go in-depth but in a nutshell, while normal camera sensors collect light in the red, green and blue spectrums, this new sensor adds a fourth pixel element that is 'clear' and who's sole purpose is to capture a broad spectrum of light that can then be combined with the other pixels providing a bright image in low light or quick shutter situations. 

Now as can be seen in the image above and description below, the technology is actually capable of 4k2k and fast frame rate FHD video so the Moto X is only taking advantage of some of the potential of this technology.  One thing to note is the ability of not only the rear, but the front camera of the Moto X having the ability to capture Full HD video, which is rare among front cameras on mobile devices and is testament to the power of this chip.  You can find out much more detail about the technology behind this 'Clear Pixel' technology found in the Moto X in the product brief I've linked below from the Omnivision site.  It'll be very interesting to see the photo comparisons against competing cameras from other leading smartphone vendors to see if the camera in the Moto X shows a clear advantage, especially in low light situations.

OmniVision Launches Native 16:9 10.5-Megapixel RGBC Camera Solution for Smartphones and Tablets

OV10820 Enables Ultra High Resolution 4K2K Video Recording with New RGBC Color Filter Format to Double Low-Light Sensitivity

SANTA CLARA, Calif., Aug. 1, 2013 /PRNewswire/ -- OmniVision Technologies, Inc. (NASDAQ: OVTI), a leading developer of advanced digital imaging solutions, today announced a complete 10.5-megapixel camera solution with a new RGB Clear (RGBC) color filter that delivers exceptional low-light performance. The camera solution is composed of a native 16:9 OV10820 sensor that offers 4K2K and 1080p full high definition (FHD) video, and a new OV660 companion chip that converts the RGBC data into standard RGB Bayer data. The combination of the OV10820 and OV660 provides an ultra-compact, complete high performance camera solution for next-generation smartphones and tablets.

"The inherent tradeoff between smaller pixels and improved sensitivity or image quality continues to drive innovation. The OV10820 delivers the best of both worlds: 10.5-megapixel high resolution imaging with unparalleled low-light sensitivity from RGBC in a compact footprint," said Devang Patel, senior product marketing manager at OmniVision. "The sensor offers 4K2K and fast frame rate FHD video in a native 16:9 aspect ratio, addressing the need to capture video for increasingly popular widescreen mobile displays and next-generation TVs with extremely high resolutions. Furthermore, the OV660 companion chip converts the RGBC data into RGB Bayer format, allowing manufacturers to integrate the camera solution with standard ISPs."

The 1/2.6-inch OV10820 utilizes a 1.4-micron OmniBSI-2 pixel architecture with a RGBC color filter pattern to deliver exceptional low-light sensitivity, enabling high quality video recording in difficult lighting conditions. It records full-resolution 10.5-megapixel video at 30 frames per second (FPS), and supports 4K2K (3840 x 2160 pixels) at 30 FPS and 1080p FHD video at 60 FPS while maintaining full field of view (FOV) with binning functionality for RAW output. The OV10820 fits in a camera module form factor of 9.5 x 9.5 x 6.4 mm, which includes auto focus functionality.

The OV660 converts OmniVision's RGBC RAW data into industry standard RGB Bayer RAW data. The OV660 supports a primary RGBC camera sensor of up to 20-megapixel in resolution and a secondary RGBC front-facing camera sensor. The OV660 eliminates the need for manufacturers and backend processors to modify their existing standard Bayer imaging pipeline and algorithms. The OV660 is available in a 4 x 4 mm WLCSP package.

The OV10820 features a high-speed 4-lane MIPI output interface to support the required high data transfer rate. The OV660 features two MIPI input ports and one MIPI output port. Both devices are currently shipping in volume production.
