Claim:
1. A method for processing successive digital image data in images, acquired by a camera immersed in a liquid, wherein said liquid comprises differences in temperature resulting in local variations of index and involving a turbulence causing an effect of apparent displacement of pixels of the images, and wherein the method comprises: a modeling of the effect of the turbulence on the pixels of the images, and a de-convolution by said modeling of a time-averaged image, wherein the time-averaged image is estimated by a recursive temporal filtering, and wherein the average image I α (x,n), estimated at the time n for a pixel with vector coordinates x, is given by: the term α being a real number corresponding to the forgetting factor, and wherein an n th output of the temporal filter, for the time n, denoted I f (x,n), and the average image I α (x,n) are linked by the equations:
