Classification: CPC H | IPC H

Claim 4:
5. The image sensor of claim 4, further comprising:
a second monitoring circuit located on the first side of the pixel area, including a third transistor and a fourth transistor connected to each other in series between the power voltage and a second monitoring line, the third transistor and the fourth transistor being configured to receive the first driving signal and a third driving signal respectively and to generate a second monitoring signal on the second monitoring line,
wherein the plurality of driving signals further include the third driving signal, and
wherein the third transistor and the fourth transistor do a logic AND operation of the first driving signal and the third driving signal to generate the second monitoring signal,
further comprising:
a second current source connected to the second monitoring line and configured to provide a second current to the second monitoring line,
wherein the detector is further connected to the second monitoring line and configured to detect a second error on the first driving signal or the third driving signal based on the second monitoring signal.
