The properties of the output optical image are investigated by taking squeezed c oherent states as the input image in the parametric image amplifier.Our results show that the squeezing degree and squeezing direction of the output optical ima ge can be controlled by the parametric image amplifier,namely,the increase or de crease of the squeezing degree and the change of the squeezing direction are dep endent on the parameter selection of the parametric image amplifier.
