Abstract
A radiation imaging apparatus comprising a pixel array in which a plurality of pixels are arrayed and a processor configured to generate a radiation image based on radio-photons which have entered the pixel array, wherein the processor performs a first process of obtaining a value of a signal from each of the plurality of pixels as a pixel value, a second process of selecting at least one of the plurality of pixels as a reference pixel, and a third process of specifying a detection area of a radio-photon in the pixel array by sequentially referring to pixel values of pixels around the reference pixel as a starting point.
