Abstract
There is provided a method of capturing a thermal pattern by a sensor including a matrix of several rows and columns of pixels, and heating elements, each heating element associated with at least one pixel, and configured to heat a heat sensitive measurement element for measurement of the pixel independently of other heating elements during reading of the pixel, the method including, during a reading of at least one first pixel, the heat sensitive measurement element of the at least one first pixel is heated by a heating element associated with the at least one first pixel, and also during the reading, the heat sensitive measurement element of at least one second pixel is heated by at least one other heating element associated with the at least one second pixel, the at least one second pixel being read before or after the reading of the at least one first pixel.
