Claim:
1. A solid-state image pick-up apparatus, comprising: a pixel including a photoelectric conversion portion and a transfer transistor configured to transfer a charge in the photoelectric conversion portion; and a signal output circuit configured to supply selectively a first voltage to turn on the transfer transistor and a second voltage to turn off the transfer transistor to the transfer transistor, wherein the signal output circuit is configured to supply the second voltage having a voltage value selected from two or more different voltage values based on an output signal from the pixel, the signal output circuit is configured to supply the second voltage having a first voltage value in a case where the output signal from the pixel is smaller than a threshold and supply the second voltage having a second voltage value different from the first voltage value in a case where the output signal from the pixel is larger than the threshold, and the second voltage value is a voltage value between a voltage value of the first voltage and the first voltage value.
