RGB-NIR PROCESSING AND CALIBRATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 17804096 titled 'RGB-NIR PROCESSING AND CALIBRATION

Simplified Explanation

The patent application describes a method for processing images captured by a multi-spectral RGB-NIR sensor. Here are the key points:

• The method starts by receiving a digital image from the RGB-NIR sensor, which captures red, green, blue, and near infra-red (NIR) pixels.
• The NIR contribution to each R, G, and B pixel value is interpolated, resulting in an NIR image.
• The NIR contribution is then subtracted from each R, G, and B pixel value in the original image, creating a decontaminated RGB-NIR image.
• From the decontaminated image, a red, green, and blue (RGB) Bayer image is constructed.
• Finally, the Bayer image is processed to obtain a full-color image.

Key points:

• Method for processing images from a multi-spectral RGB-NIR sensor.
• Interpolation of NIR contribution to each R, G, and B pixel value.
• Subtraction of NIR contribution to obtain a decontaminated RGB-NIR image.
• Construction of a Bayer image from the decontaminated image.
• Processing of the Bayer image to obtain a full-color image.

Original Abstract Submitted

A method for processing images acquired by a multi-spectral RGB-NIR (red/green/blue/near infra-red) sensor includes receiving a RGB-NIR digital image from a multi-spectral RGB-NIR sensor, interpolating an NIR contribution to each R, G and B pixel value, wherein an NIR image is obtained, subtracting the NIR contribution from each R, G and B pixel value in the RGB-NIR digital image wherein a decontaminated RGB-NIR image is obtained, constructing a red, green and blue (RGB) Bayer image from the decontaminated RGB-NIR image, and processing the Bayer image wherein a full color image is obtained. The RGB-NIR digital image includes red (R) pixels, green (G) pixels, blue (B) pixels, and NIR pixels, and every other row in the RGB-NIR digital image includes NIR pixels that alternate with green pixels, and every other row in the RGB-NIR digital image includes green pixels that alternate with red and blue pixels.
