Sony patents method to boost color accuracy in spectral cameras
Sony describes a system that calculates how a camera sensor reacts to specific light sources and objects. It uses this data to create a mathematical formula that reconstructs detailed color information from the sensor's limited data.
In the filing’s own words
An information processing apparatus estimates a sensor input that is spectral information of input light to a spectral sensor on a basis of spectral reflectance information of a target subject and spectral information of a target light source; estimates a sensor output that is spectral information output by the spectral sensor according to the sensor input on a basis of spectral sensitivity information of the spectral sensor and the sensor input; and obtains an arithmetic algorithm that minimizes error between a wavelength characteristic indicated by post-narrow-band spectral information obtained by performing narrow-band processing based on the sensor output and a wavelength characteristic indicated by the sensor input as an arithmetic algorithm of the narrow-band processing that is processing of estimating spectral information on a larger number of wavelengths than a number of output wavelengths of the spectral sensor on a basis of the output spectral information of the spectral sensor.
What exactly they claim (claim 1)
1. An information processing apparatus comprising: a sensor input estimation unit that estimates a sensor input that is spectral information of input light to a spectral sensor on a basis of spectral reflectance information of a target subject and spectral information of a target light source; a sensor output estimation unit that estimates a sensor output that is spectral information output by the spectral sensor according to the sensor input on a basis of spectral sensitivity information of the spectral sensor and the sensor input; and a derivation processing unit that obtains an arithmetic algorithm that minimizes an error between a wavelength characteristic indicated by post-narrow-band spectral information obtained by performing narrow-band processing based on the sensor output and a wavelength characteristic indicated by the sensor input as an arithmetic algorithm of the narrow-band processing that is processing of estimating spectral information on a larger number of wavelengths than a number of output wavelengths of the spectral sensor on a basis of the output spectral information of the spectral sensor.
