Sony patents method to boost color accuracy in cameras using light data
Sony describes a system that improves how cameras capture colors by estimating how a sensor reacts to specific light sources. It uses this data to create a calculation that fills in missing color details, making the final image match the real object more closely.
In the filing’s own words
An information processing device includes: a sensor output estimation processing unit that estimates, on the basis of spectral reflectance information of a target subject and spectral information of a target light source, a sensor output that is output spectral information in a case where a spectral sensor has sensed the target subject irradiated with light from the target light source; and a derivation processor that obtains, as a computation algorithm of band-narrowing processing that is processing of estimating spectral information for a larger number of wavelengths than the number of output wavelengths of the spectral sensor on the basis of the output spectral information of the spectral sensor, a computation algorithm that minimizes an error between a wavelength characteristic indicated by post-band-narrowing spectral information obtained by executing the band-narrowing processing based on the sensor output and a wavelength characteristic indicated by the spectral reflectance information of the target subject.
