Abstract

See full text

The present invention relates to a light sensing system for sensing ambient light intensity, comprising a light sensing device with at least one light sensor and a calibration device for calibrating the sensor. The calibration device comprises at least one light source that emits light with a standard intensity. The invention is further related to a corresponding method for calibrating a light sensing device, comprising the illumination of the light sensor of the light sensing device with light that has a standard intensity, the comparison of the output intensity signal of the sensor with an expected signal that corresponds to the standard intensity, and the matching of the output intensity signal of the sensor to the expected signal by adjusting a gain parameter of the sensor.
