1. An imaging device having:

  • pixels being disposed two-dimensionally, in matrix, and having a photoelectric conversion part converting a light into an electric signal;

    a plurality of vertical signal lines each coupled to a plurality of the pixels in a column direction and receiving an optical signal containing optical information and a reset signal containing a noise component from the pixels;

    a column amplifier amplifying the optical signal and the reset signal read to each of the vertical signal lines; and

    a holding part holding each of the optical signal and the reset signal amplified in the column amplifier, the imaging device comprising;

    a first clip driving circuit being disposed between each of the vertical signal lines and the column amplifier and clips a signal out of a predetermined voltage;

    a first clip voltage generation circuit giving a clip voltage to the first clip driving circuit;

    a second clip driving circuit being disposed between the column amplifier and the holding part and clips a signal out of a predetermined voltage; and

    a second clip voltage generation circuit giving a clip voltage to the second clip driving circuit.
