IMAGING DEVICE
First Claim
1. An imaging device comprising:
- pixels arranged in a two-dimensional form and each having a photoelectric conversion part converting light into an electric signal;
a plurality of vertical signal lines coupled, in a column direction, to the pixels arranged in the column direction and receiving the electric signal read from each of the pixels;
a first constant current generator provided on each of the vertical signal lines;
a column amplifier having a second constant current generator amplifying the electric signal read to the vertical signal line; and
a constant voltage generator provided on each of the vertical signal lines and being coupled to a first contact of the first constant current generator and a second contact of the second constant current generator included in the column amplifier.
