Abstract:
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.
