An image pickup unit includes: an image pickup section including a plurality of pixels, the pixels each including a photoelectric transducer and a field-effect transistor; and a drive section switching the transistor between an on operation and an off operation to perform a read operation and a reset operation of a signal charge accumulated in each of the pixels. The transistor includes a first gate electrode and a second gate electrode with a semiconductor layer in between, the drive section applies a first voltage and a second voltage to the first gate electrode and the second gate electrode of the transistor, respectively, to switch the transistor between the on operation and the off operation, and the drive section adjusts timings of switching the first and second voltages between an on-voltage and an off-voltage, on-voltage values of the first and second voltages, or both thereof to be different from each other.
