Abstract
In X-ray photography by an X-ray equipment, grid images based on only a grid are acquired by a grid image generating circuit under various photograph conditions, and are stored in image memories. A subject image based on a subject to be examined is acquired under a predetermined photograph condition. A grid image which is acquired under the same photograph condition as that of the subject image or under a condition similar thereto is read out from a corresponding image memory. The subject image and the readout grid image are regulated by gain regulators to have the same gain. The subject image is then divided by the grid image in the divider. As a result, the subject image without the grid image can be obtained.
