Abstract: The present disclosure relates to a method of manufacturing a light sensor comprising a matrix of pixels each associated to a micro-lens having a shift with respect to the pixel. For each axis of a plurality of axes passing by the optical center of the matric, for each pixel on the axis, and for each of a plurality light incident angles, a response value of the pixel is obtained. Based on the response values, for each axis and each pixel on the axis, a first function providing the light incident angle for which the pixel has the best response value is determined. For each axis and each pixel on the axis, a second value of the shift for bringing closer the first function to a target function is determined. The sensor is manufactured using the second values of shift.
