ABSTRACT:
A read-out operation is carried out in which a stimulable phosphor sheet having a radiation image stored thereon is exposed to stimulating rays, which cause it to emit light in proportion to the amount of energy stored thereon during its exposure to radiation, the emitted light is photoelectrically detected and read-out image signal is thereby obtained. A reproducing operation is then carried out in which the read-out image signal is used to reproduce a visible radiation image. A radiation image read-out and reproducing method comprises the steps of carrying out processing which obtains information from the read-out image signal, said information being used to determine the conditions under which image processing is to be conducted, and at least one type of image processing, which can be conducted without the information being used, during the period of time from when the read-out operation is being carried out to when the reproducing operation is begun. After the reproducing operation is begun, image processing, wherein the optimum image processing conditions are determined on the basis of the information, is carried out.
