Image processing apparatus for a moving image of an object irradiated with radiation, method thereof, and storage medium |
摘要 |
A radiation imaging apparatus comprises: an imaging unit to capture a moving image of an object irradiated with radiation; a first extraction unit to extract an object area where an object exists from an exposure field region of radiation in a first frame image of the moving image; a second extraction unit to extract a region of interest as a target for calculation of a first feature amount indicating a feature of an image from a region corresponding to the object area in a second frame image following the first frame image; a first calculation unit to calculate the first feature amount of a region of interest in a third frame image following the second frame image from a region corresponding to the region of interest in the third frame image; and a control unit to control a radiation generating unit based on the first feature amount.
