Patent drawing
Patent drawing from the official filing.

Samsung describes a device with two cameras facing opposite directions, where the lower-resolution rear camera measures the surrounding light. The phone then uses this data to adjust the color balance of photos taken by the main front camera.

Why it mattersThis could make photos look more natural by automatically correcting for different indoor lighting conditions.

In the filing’s own words

An electronic device includes: a first camera oriented in a first direction with respect to the electronic device; a second camera oriented in a second direction with respect to the electronic device, wherein the second direction is opposite to the first direction; and an image signal processor configured to: obtain a first image captured by the first camera; obtain information about ambient light captured by the second camera; calculate a color temperature based on the information about the ambient light; and perform color correction on the first image based on the calculated color temperature to obtain a color-corrected first image

What exactly they claim (claim 1)

1. An electronic device, comprising: a first camera oriented in a first direction with respect to the electronic device; a second camera oriented in a second direction with respect to the electronic device, wherein the second direction is opposite to the first direction; and an image signal processor configured to: receive a first image captured by the first camera by capturing a first object; receive a second image captured by the second camera by capturing a second object; calculate a color temperature based on the second image about ambient light that illuminates the first object; and perform color correction on the first image based on the calculated color temperature to obtain a color-corrected first image, wherein the first camera comprises a first image sensor having a plurality of first photodiodes and a first resolution, and wherein the second camera comprise a second image sensor having a plurality of second photodiodes and a second resolution less than the first resolution.
