    摘要： An imaging device includes: a pixel unit having M (M is an integer of 2 or more) pixel arrays each including N (N is an integer of 2 or more) pixel portions; and M circuit units. Each circuit unit includes: N charge amplifiers for converting charge signals output from the pixel portions of the corresponding pixel array into voltage signals; N A/D converters each including an addition processing portion for performing addition processing on the voltage signals and a holding portion for holding an addition signal corresponding to an addition state of the addition processing portion; and a switch circuit for switching connection states between the charge amplifiers and the holding portions of the A/D converters. The switch circuit switches the connection state so that the holding portion for holding the addition signal corresponding to the charge signal output from the pixel portion is switched in accordance with the arrangement order of the N pixel portions.

    摘要： An X-ray image acquisition device includes a pixel unit having M pixel arrays each including N pixel portions (N and M are integers of 2 or more), M circuit units, and a control unit. Each circuit unit includes T (T is an integer of N or more) adding sections that sequentially add electrical signals corresponding to output signals from the N pixel portions and a switch section for switching connection states between the N pixel portions and the T adding sections. The control unit switches the connection states in synchronization with the transportation of an object along a first direction so that the electrical signals corresponding to the output signals output from the pixel portions by detecting X-rays transmitted through the same region of the object are added by the same adding sections.
