Abstract: The invention relates to a method of inspecting packages with the help of a linear image sensor. According to the invention the method comprises the steps of: for each movement increment, cyclically acquiring a sequence of n successive image lines (l1, l2, . . . , ln), the n image lines of each sequence being obtained with exposure times (Ti) and/or lighting conditions (Ek) that are different; grouping together the image lines (l1, l2, . . . , ln) obtained in the sequences while using both the same exposure times (Ti) and the same lighting conditions (Ek) so as to obtain n superposable images (I1, I2, . . . , In) of at least j image lines; and analyzing the n images (I1, I2, . . . , In) separately or in combination in order to determine at least one characteristic of the packages.
