An image represented by samples No,o, N2,o, . . . , N2p,o, . . . , No,2, . . . , No,2q, . . . , N2p,2q, . . . , distributed over a two-dimensional pattern and each represented by a quantified signal, generally at two levels, is restored. From samples such as N2p,2q, are reconstituted samples such as m2p,2q, m2p+1,2q, m2p,2q+1, m2p+1,2q+1, quadruple in number. The values of the four samples are generated according to the expansion relationships: <IMAGE> The samples N are typically obtained by a compression process.
