Motorola Moto X new Clear Pixel camera and Aptina Clarity Plus explained31
To understand the new Clarity Plus, we have to first understand digital cameras. The sensor of a camera consists of pixels that by themselves can only capture the intensity of light, but not its color. That’s why, on top of the sensor, manufacturers place a color filter array. Thus, each pixel is covered with a color-sensitive mosaic, so that the sensor can record that color information.
So while in traditional Bayer each element of the filter mosaic corresponds to a particular color, in Clarity+ only 50% of the filter elements translate into color directly. That means the other half lets all light in, without filtering it, so we have double the amount of light sensitivity in a Clarity Plus module.
That has huge implications, of course. More light means better images in low-light and faster shutter speeds in good lighting conditions. The difference is dramatic. In practical terms Aptina promises that its 13-megapixel cameras with smaller 1.1µm pixels can match the light sensitivity of 8-megapixel 1.4µm-pixel sensors.
Good news is that Aptina has already integrated the proprietary ISP in some chips and it is talking with other SoC manufacturers to include the imaging chip in their new designs. If Motorola’s upcoming Moto X indeed uses Aptina’s Clarity Plus technology marketting it as ‘Clear Pixel’ that could be one explanation as to why it uses the slightly dated Snapdragon S4 Pro MSM8960. Integrating the ISP might have simply been only done for it.
Motorola Moto X has already shown up in the hands of Google Chairman Eric Schmidt and that’s as close to an official confirmation as it gets. Motorola tweeted a blurry low-light image of a kid obviously teasing that its next cameraphone won’t have that issue. Everything seems to fall together.
