Abstract A method (500) for determining a phase for a captured image (121) comprising forming (420) a demodulated image (405) defining wrapped phase values and modulation values, each being associated with at least one region (123) in the captured image; identifying (1010) a position 5 (el) of an edge (1011) in the captured image dependent upon the plurality of modulation values; determining (1020) a position of substantial change (1021, 1022) in the wrapped phase values in the captured image dependent upon the identified position of the edge, and determining (530) at least one unwrapped phase value based on the position of the edge and the position of the substantial change in the wrapped phase values by shifting a position of the 10 substantial change in the wrapped phase values to the identified position of the edge, so that said unwrapped phase value is adjusted by at least one cycle Pn941 R2 / R185R04 2 . .. .. . . . . . . . . . . . . . ..r . . .. . .a . . . . .. . . . .
