Samsung patents camera system that uses standard photos to fix color accuracy

Samsung describes a device with two separate cameras: one that captures standard red-green-blue images and another that captures data across four or more color channels. A processor aligns these images and uses the standard photo as a guide to adjust the data from the multi-channel camera, ensuring the colors are accurate.

Why it mattersThis could help phones or cameras produce more precise color data for tasks like scanning documents or analyzing materials, though it is unclear if this will appear in consumer devices.

In the filing’s own words

An image acquisition device, including: a multispectral image sensor configured to acquire a first image using four or more channels; a red-green-blue (RGB) image sensor configured to acquire a second image using a red (R) channel, a green (G) channel, and a blue (B) channel; and a processor configured to perform calibration on the acquired first image, based on a guided image generated based on the second image.

What exactly they claim (claim 1)

1. An image acquisition device comprising: a multispectral image sensor configured to acquire a first image using four or more channels; a red-green-blue (RGB) image sensor configured to acquire a second image using a red (R) channel, a green (G) channel, and a blue (B) channel; and a processor configured to perform calibration on the acquired first image, based on a guided image generated based on the second image, wherein the processor is further configured to: perform registration on the first image to obtain a registered first image, and perform the registration on the second image to obtain a registered second image, and generate the guided image based on the registered second image on which the registration has been performed with respect to the registered first image, and perform calibration on the first image, based on the guided image.
