Abstract: Disclosed is a method for reconstructing a matrix image representative of a static scene under predetermined lighting conditions, including: —acquiring images, captured by a sensor using a lighting which is separate from one image to another; and —reconstructing the matrix image, in a reconstruction space separate from a native spectral space of the sensor, by determining, for each pixel, the spectral components by weighted combination of the spectral components of the native spectral space of the image sensor, the spectral components being photometrically adjusted and associated with the same pixel of each image of the captured images. the weighting is obtained by solving a linear equation system having at least the following parameters: a predetermined value matrix associated with the predetermined lighting conditions, a matrix representative of both the spectral response of the sensor and the spectral distribution of each lighting applied to each captured image.
