Sony patents method to make different color sensors see the same colors

Sony has filed a patent for a software method that adjusts data from one type of color sensor to match the output of another. The system calculates specific mathematical coefficients to convert the raw data, ensuring that two different sensors produce consistent results despite having different physical sensitivities to light.

Why it mattersThis could help standardize color accuracy across different camera models or devices, making it easier for users to trust that what they see on one screen matches what another device captures.

In the filing’s own words

Provided is an environment in which a sensor output of a spectroscopic sensor can be handled without considering a variation in spectral sensitivity of the spectroscopic sensor. An information processing device according to the present technology includes a coefficient calculation unit configured to calculate a coefficient included in a conversion algorithm for converting first sensor output into different output, the first sensor output being spectral information output by a first spectroscopic sensor, wherein the coefficient calculation unit calculate the coefficient so that the different output obtained by inputting the first sensor output to the conversion algorithm approaches second sensor output, the second sensor output being spectral information output by a second spectroscopic sensor different from the first spectroscopic sensor.

What exactly they claim (claim 1)

1. An information processing device comprising: a coefficient calculation unit configured to calculate a coefficient included in a conversion algorithm for converting first sensor output into different output, the first sensor output being spectral information output by a first spectroscopic sensor, wherein the coefficient calculation unit calculate the coefficient so that the different output obtained by inputting the first sensor output to the conversion algorithm approaches second sensor output, the second sensor output being spectral information output by a second spectroscopic sensor different from the first spectroscopic sensor.
