Provided is an image capture device with which lag is alleviated while having a short image capture operation gap, and with which it is possible to acquire an image with a good signal-to-noise ratio. An image capture device comprises: a detector (104), further comprising a plurality of conversion elements (201) which have a semiconductor layer positioned between a first electrode and a second electrode and which convert radiation or light into an electrical charge, said detector (104) carrying out an image capture operation which outputs an electrical signal based on the electrical charge a power supply unit (107) which supplies a first voltage to the conversion elements (201) for the conversion elements (201) in the image capture operation to convert the radiation or light to the electrical charge and a control unit (106) which controls the detector (104) and the power supply unit (107). A first image capture interval operation, in which a second voltage which differs from the first voltage is applied to the conversion elements (201) in the period between the first image capture operation and the second image capture operation, and a second image capture interval operation, in which a third voltage which differs from the first voltage and the second voltage is applied to the conversion elements (201) after the first image capture interval operation, are carried out. The absolute value of the difference between the third voltage and the first voltage is smaller than the absolute value of the difference between the second voltage and the first voltage.Linvention porte sur un dispositif de capture dimage au moyen duquel un retard est atténué tout en ayant une courte discontinuité dopération de capture dimage, et au moyen duquel il est possible dacquérir une image avec un bon rapport signal sur bruit. Un dispositif de capture dimage comprend : un détecteur (104), comprenant en outre une pluralité déléments de conversion (201) qui comprennent une couche de semi-conducte
