Claim:
1. A radiation imaging system including an X-ray sensor and an image processing apparatus which performs abnormality determination concerning a correction image obtained by irradiating the X-ray sensor with X-rays without an object to be examined disposed between the X-ray sensor and an X-ray generator, the system comprising: an area acquisition unit configured to acquire information of partial areas of the correction image; a distribution acquisition unit configured to acquire distribution information representing variation in pixel value for each of the acquired partial areas; a determination unit configured to determine that adjacent partial areas can be integrated in a case where the distribution information representing variation for the adjacent partial areas fall within a threshold range, wherein the determination unit determines, based on the distribution information, whether abnormality is included in the correction image; and an integration processing unit configured to integrate the adjacent partial areas based on the determination result.
