| description | Method for capturing a thermal pattern by a sensor comprising a plurality of pixels each comprising a heat-sensitive measuring element, the method comprising, for each pixel:heating the measuring element;first reading of the electrical charges outputted by the pixel during a first measurement duration and giving a first measurement value x1;second reading of the electrical charges outputted by the pixel during a second measurement duration and giving a second measurement value x2;calculating a difference x1−α·x2, where α is a positive real number,and wherein more than half of the heating duration is implemented during the first measurement duration and less than half of the heating duration is implemented during the second measurement duration. |
