<p>The invention relates to a device (18) for compressing an image for an image sensor (10), comprising a module (3O1,..., 3ON) for the analog decorrelation of an image for providing low-frequency coefficients and high-frequency coefficients from said image, and an analog-digital coefficient converter (361,..., 36N). The device further includes a module (321,..., 32N, 341,..., 34N) for the differentiated analog amplification of the low-frequency coefficients as well as of the high-frequency coefficients supplied by the analog decorrelation module (3O1,..., 3ON) in order to feed modified coefficients to the converter (361,..., 36N).</p> |
