Abstract
According to a radiation imaging apparatus, any separate AEC sensor need not be prepared. Additionally, the apparatus main body can be made compact. To accomplish this, the radiation imaging apparatus has a first optical conversion element that converts incident radiation into an electrical signal, and generates image information on the basis of the electrical signal output from the first optical conversion element. Below a portion that is aligned to the gap between the first optical conversion elements, a plurality of second optical conversion elements which detect the incident amount of the radiation from the gap are formed. Exposure control for the radiation or control of the optical conversion elements is executed on the basis of the detection result by the second optical conversion element.
