Abstract

Official abstract text for this publication.

In one implementation, an image sensor is calibrated by determining a spectral characterization for each image window of an image sensor, correlating the spectral characterization for each image window of the image sensor with a spectral property of a target illuminant, and generating a scale factor for each image window of the image sensor. The scale factor for each image window of the image sensor is generated based on the correlating.

First claim

Opening claim text (preview).

What is claimed is: 1. A non-transitory processor-readable medium storing code representing instructions to cause a processor to perform a process, the process comprising: determining a spectral characterization for each image window of an image sensor; correlating the spectral characterization for each image window of the image sensor with a spectral property of a target illuminant; and generating a scale factor for each image window of the image sensor based on the correlati…
