    摘要： A device for generating an image from an IR radiation including a plurality of polarized heat detectors (2) having specific electric resistances distributed over the focal plane of a detection module so as to deliver a signal representing a detected IR radiation. A read module (8) converts the electric signal into a signal usable by an image processing block (18). An electric signal compensation module (10) having a first branch (12) for obtaining a first thresholding to extract a first constant value signal due to the polarization of the heat detectors. The compensation module (10) includes a second branch (30) for obtaining a second thresholding to extract from the first thresholding signal a second low-level signal due to the dispersion of the electric resistances of the heat detectors and/or to the fluctuations in the temperature of the focal plane of the detection module.

    摘要： A method and a device for taking digital images in which the exposure time of the object to X or .gamma. rays is controlled and optimized in a way that produces, with each taking of an image, a non-saturated image and minimizes the dose of radiation necessary to produce this image. The device includes at least one image sensor having measurement pixels and pixels. The measurement pixels measure a current representative of a dose of radiation received by the object, and the image pixels are used to form the digital image. The dose of radiation measured by the measurement pixels is compared to a guide-line value, and when this dose measurement reaches the guide-line value the collection of the electrical charge by the image pixels is stopped. The stopping of the collection of the electrical charges is performed without stopping the radiation emission.
