Samsung patents camera system that blends two sensors for better color

Patent drawing
Patent drawing from the official filing.

Samsung describes a camera setup using two different image sensors to capture photos. One sensor has high detail but a narrow color range, while the other has lower detail but captures a wider spectrum of light. A processor aligns these images and blends their color data to create a final picture with improved color accuracy.

Why it mattersThis technique could help future phones or cameras produce more vibrant and accurate colors by combining the strengths of two different types of sensors.

In the filing’s own words

An image acquisition device includes a first image sensor having a first spatial resolution and configured to acquire a first image based on a first wavelength band, a second image sensor having a second spatial resolution lower than the first spatial resolution and configured to acquire a second image based on a second wavelength band wider than the first wavelength band, and a processor configured to register the first image and the second image by using a relative position information between the first image sensor and the second image sensor; generate a third image, of which a color component is determined by replacing a color component of the first image with a color component of the second image; and generate a fourth image, of which a color component is determined by synthesizing the color component of the first image and the color component of the third image through alpha blending.

What exactly they claim (claim 1)

1. An image acquisition device comprising: a first image sensor having a first spatial resolution and configured to acquire a first image based on a first wavelength band; a second image sensor having a second spatial resolution lower than the first spatial resolution and configured to acquire a second image based on a second wavelength band wider than the first wavelength band; and a processor configured to: register the first image and the second image in association with each other, by using a relative position information between the first image sensor and the second image sensor; generate a third image, of which a color component is determined by replacing a color component of the first image with a color component of the second image; and generate a fourth image, of which a color component is determined by synthesizing the color component of the first image and the color component of the third image through alpha blending.
