Light source color coordinate estimation system and deep learning method thereof

Abstract

A light source color coordinate estimation system and a deep learning method thereof are provided. The light source color coordinate estimation system includes a plurality of photo detectors, a normalization calculation circuit, and a neural network. The photo detectors generate spectral responses after receiving a beam emitted by a light source. The spectral responses respectively have different detection wavebands and energy integral values corresponding to the detection wavebands. The normalization calculation circuit respectively divides the energy integral values by a largest of the energy integral values to generate a plurality of normalized energy integral values. An input end of the neural network receives the normalized energy integral values and converts the normalized energy integral values into an estimated color coordinate. An output end of the neural network outputs the estimated color coordinate.
