ABSTRACT:
A method of adjusting read-out processing conditions for a radiation image comprises the steps of calculating the maximum image signal level Smax and the minimum image signal level Smin of a desired image information range from image signals for condition adjustment which represent a radiation image, and adjusting the read-out processing conditions on the basis of the maximum image signal level Smax and the minimum image signal level Smin thus calculated. At least one of the maximum image signal level Smax and the minimum image signal level Smin is determined on the basis of a difference histogram of the image signals for condition adjustment.
