1. imaging device comprises:

  • Comprise the detecting unit that follows with a plurality of pixels of column direction configuration, wherein, each in the pixel comprises the conversion element and the switch element that is used to transmit the signal of telecommunication corresponding with electric charge that is used for incident radioactive ray or incident light are converted to electric charge;

    Be used to drive a plurality of switch elements of following direction configuration with drive circuit unit from the pixel parallel transmission signal of telecommunication that follows the direction configuration;

    The reading circuit unit that is used for the parallel read-out signal of telecommunication;

    Wherein, the reading circuit unit comprises and is used for from first sampling and the holding circuit of sampling along the signal of telecommunication of the pixel of a row configuration of detecting unit and keeping and be used for second sampling and holding circuit that signal of telecommunication of the pixel that disposes from another row along detecting unit is sampled and kept;

    Being used for will be from the signal of telecommunication parallel transmission of a plurality of pixels that the follow direction configuration a plurality of distribution of reading to said reading circuit unit;

    Wherein, said a plurality of distribution of reading comprises with first sampling and the corresponding configuration of holding circuit and is connected to jointly along first on the pixel of a said row configuration and reads distribution and with second sampling and the corresponding configuration of holding circuit and be connected to said another in edge jointly and be listed as second on the pixel that disposes and read distribution;

    WithBe used to control the control unit of reading circuit unit, wherein, control unit control reading circuit unit makes the sampling of winning carry out sampling and maintenance with second sampling and holding circuit in different each other timings with holding circuit.
