A method of capturing a thermal pattern by a sensor comprising a matrix of several rows and columns of pixels and a plurality of heating elements, each heating element being associated with a pixel or a group of pixels, and each heating element being capable of heating a heat sensitive measurement element for measurement of the pixel or each pixel in the group of pixels independently of the other heating elements during reading of the pixel or of at least one of the pixels in the group of pixels, in which, during a reading of a first pixel or of a first group of pixels, the heat sensitive measurement element of this first pixel or of each pixel of the first group of pixels is heated by the heating element associated with this first pixel or with this first group of pixels, and the heat sensitive measurement element of another pixel called second pixel, or of a second group of pixels, in the matrix is heated simultaneously by at least one other heating element associated with this second pixel or with this second group of pixels, the at least one other heating element being distinct from the heating element associated with the first pixel or with the first group of pixel, the second pixel or the second group of pixels being intended to be read before or after the reading of the first pixel or of the first group of pixels, in which the second pixel is adjacent to the first pixel or to a third pixel being intended to be read after the first pixel and in which the heating current injected into the heating elements is modulated so that the intensity of the heating current, injected into the at least one other heating element associated with the second pixel or with the second group of pixels, is different from the intensity of the heating current injected into the heating element associated with the first pixel or with the first group of pixels. in which, during a reading of a first pixel or of a first group of pixels, the heat sensitive measurement element of this first pixel or of each pixel of the first group of pixels is heated by the heating element associated with this first pixel or with this first group of pixels, and the heat sensitive measurement element of another pixel called second pixel, or of a second group of pixels, in the matrix is heated simultaneously by at least one other heating element associated with this second pixel or with this second group of pixels, the at least one other heating element being distinct from the heating element associated with the first pixel or with the first group of pixel, the second pixel or the second group of pixels being intended to be read before or after the reading of the first pixel or of the first group of pixels, in which the second pixel is adjacent to the first pixel or to a third pixel being intended to be read after the first pixel and in which the heating current injected into the heating elements is modulated so that the intensity of the heating current, injected into the at least one other heating element associated with the second pixel or with the second group of pixels, is different from the intensity of the heating current injected into the heating element associated with the first pixel or with the first group of pixels.
