1. A method of concealing errors in at least part of a current image in a sequence of images, comprising the following steps of: comparing the at least one part of the current image with at least one corresponding part of a previous image; determining a parameter representing a measurement of similarity between the at least one part of the current image and the at least one corresponding part of the previous image from the result of the comparison of the at least one part of the current image with the at least one corresponding part of the previous image; and selecting a temporal error concealment method or a spatial error concealment method to be applied in the at least one part of the current image, according to the result of said comparing step and at least one item of information relating to the errors concealed in the at least one corresponding part of the previous image, wherein said selecting step comprises a substep of comparing the parameter representing the measurement of similarity with a threshold determined from the at least one item of information relating to the errors concealed in the at least one corresponding part of the previous image; the threshold represents a similarity value at which the at least one current image part and the at least one corresponding previous image part are no longer considered to be similar, and the at least one item of information relating to the errors concealed and the threshold comprise an item of information representing an amount of concealed data in the at least one corresponding part of the previous image.
