Patent ID: 7110502

Claim:
A radiographic apparatus comprising: mode selection means for selecting either a first mode for imaging a still image or a second mode for imaging a moving image; a plurality of grids for removing scattered radiation from radiation which has passed through an object; grid selection means for selecting one of the plurality of grids in accordance with the selected mode; a two-dimensional detector for converting the radiation from which the scattered radiation has been removed by the selected grid into electrical signals; setting means for setting a read condition on a basis of the selected mode, which includes read pixel pitch and an amplification degree; acquisition means for acquiring an image of the object from the electrical signals on a basis of the read condition set by the setting means; and grid stripe reduction means for reducing grid stripes on the image on a basis of parameters corresponding to the read pixel pitch; wherein in the read condition, the read pixel pitch of the two-dimensional detector and the amplification degree of the second mode are larger than in the first mode.
