<p>A radiation transducing device (1) comprising an array (2) of pixel elements (8) in which a pixel element is only read out when the radiation that is incident on that pixel element exceeds a predetermined threshold value. Encoding circuits (5, 6), connected to comparators (3, 4) and radiation measuring element (21) provide a digital representation (x01, x02, x03, x04, xa0, y01, y02, y03, y04, ya0 of the portion of the pixel array, whose incident radiation amount exceeds said threshold value.</p> |
