The invention relates to a device for detecting space debris, which is designed to provide at least one image datum at a frequency sufficient for performing effective monitoring. To this end, the device includes a matrix image sensor, wherein each image point detection element (11) comprises an integrated function for determining an image point variation. The result of said image point variation is binary. The image sensor is used in a continuous line-by-line read mode. For each line, when said line contains an image point detection element, the image point variation of which is positive, a column containing said element is determined, and a code for said column constitutes the image datum. |
