Abstract
A pixel matrix is arranged in line of pixels. Each pixel is either in a first state or in a second state. The matrix mainly contains pixels in the second state. Each line of pixels is tested in order to determine whether it contains or not a pixel in a first state. The result from this test for each line is sent into a receiver. The lines including at least one pixel in the first state are more accurately analyzed in order to determine the position of this or these pixel in the line.
