Nvidia patents camera method for fixing color and brightness

Nvidia describes a system where a processor adjusts the color channels of a photo taken by a camera. It then calculates brightness levels using these adjusted colors and the camera's exposure settings to create a final, updated image.

Why it mattersThis filing details a specific way to improve how digital cameras process light and color, which could lead to sharper or more accurate photos in Nvidia's hardware.

In the filing’s own words

An imaging system comprises a camera and one or more processors. The one or more processors are to process a plurality of channels associated with color information in a color space of an image captured by the camera to generate a second plurality of channels associated with corrected color information in a corrected color space. The one or more processors are further to determine a plurality of luminance values based at least in part on the second plurality of channels and an exposure value of the camera, and generate an updated version of the image using the plurality of luminance values.

What exactly they claim (claim 1)

1. An imaging system, comprising: a camera; and one or more processors to: process a plurality of channels associated with color information in a color space of an image captured by the camera to generate a second plurality of channels associated with corrected color information in a corrected color space; determine a plurality of luminance values based at least in part on the second plurality of channels and an exposure value of the camera; and generate an updated version of the image using the plurality of luminance values.
