Abstract
Official abstract text for this publication.
Systems, methods, and other embodiments associated with producing spatially varying spectral response calibration data are described. One example method includes controlling a digital camera to capture characteristic data arrays from light sensors in the digital camera in response to the digital camera being exposed to light stimuli from a multi-spectral reference display. The data arrays will be acquired multiple times at multiple locations in multiple stimuli provided from the multi-spectral reference display. The method also includes controlling a calibration logic to manipulate characteristic data arrays to produce spatially varying spectral response calibration data as a function of using characteristic data arrays and known wavelengths of the light in light stimuli. The method may also include providing the spatially varying spectral response calibration data to a downstream consumer (e.g., correction process, quality control process), displaying the data, or storing the data.
First claim
Opening claim text (preview).
What is claimed is: 1. A computer-implemented method, comprising: controlling a digital device to capture two or more characteristic data arrays from light sensors in the digital device in response to the digital device being exposed to two or more light stimuli provided by a multi-spectral reference display, where the wavelengths of the light in the two or more light stimuli are known, and where a characteristic data array comprises an image produced by the digital device that in…
