Apple’s multi-sensor patent soups up the iPhone’s camera color and resolution

iOS 7 Camera

As the iPhone’s camera becomes the handset’s most-used feature, Apple is increasingly looking for ways to enhance the experience. The latest example comes in a patent granted Tuesday which combines three sensors providing images with improved color saturation and lighting.

According to the patent approved by the U.S. Pantent and Trademark Office, the three-sensor technology described by Apple is part of a trend among smartphone manufacturers adopting multiple image sensors for greater mobile photography…

In the patent entitled “Image capture using luminance and chromatic sensors,” the iPhone maker outlines a trio of sensors – two devoted to color and one for detecting light. Information from the three sensors are melded into one image with greater color saturation and providing higher definition for objects.

As the patent application explains, the sensors each are equipped with a lens for focusing light. By arraying the light sensor between two chromatic sensors, the setup permits a stereo map to be created.

Such integration of three sensors permits an image that is of a quality not possible with a single sensor.

The patent abstract reads:

One embodiment may take the form of an image sensing device that includes a first image sensor for capturing a luminance image, a second image sensor for capturing a first chrominance, and a third image sensor for capturing a second chrominance image.

The image sensing device may further include an image processing module for combining the luminance image captured by the first image sensor, the first chrominance image captured by the second image sensor, and the second chrominance image captured by the third image sensor, to form a composite image.

This is not the first use of a tri-sensor arrangement for improved smartphone camera imagery. The HTC One’s UltraPixel camera also combines multiple sensors to create a single, richer image.

We’ve recently seen a number of iPhone camera-related patents from Apple, including dual-sensor technology, social flashes which link multiple iDevices, as well as attempts to cure the curse of blurry iPhone images.

    excelent, only remains to know which iPhone comes to these improvements

  • daniel bonnells

    Unfortunately, this will not be in the next iPhone. But maybe next year?

      How so? Pretty sure this would be the changes made to the camera in the supposed upcoming iPhone 5S

    i wish apple would but an audiophile quality DAC sound chip in the iphone also..

    Apple is sticking its nose in the patent wars between god and natural selection…

    I also owned a few patents, im just waiting for someone or some company to implement it or make it. And then sue them for using my patent. Boom easy money. Lol hahaha

    I’m always happy to see/hear about anything having to do with the iPhone camera. I’m one of those who uses my camera a lot, and will welcome any and all improvements!

    The new look of the camera is ugly, but would be great if the shot button were black and the background white :D
