Radiation imaging apparatus, radiation imaging system, control method of radiation imaging apparatus, and non-transitory computer-readable storage medium

Abstract

A radiation imaging apparatus is provided. The apparatus comprises an image capturing unit that is provided with pixels for converting incident radiation into electrical signals and is configured to output first image data, a storage unit configured to store position information of a first pixel which continuously outputs an abnormal pixel value, a replacing unit configured to generate second image data from the first image data by replacing a pixel value of the first pixel with a preset setting value based on the position information and a correction unit configured to detect a second pixel which is not stored in the storage unit and outputs an abnormal pixel value, and correct the pixel value of the second pixel. The correction unit detects and corrects the second pixel based on the second image data that includes the first pixel whose pixel value has been replaced.
