Abstract:
1. An image sensor comprising: a light receiving element circuit array comprised of a plurality of light receiving elements for outputting output signals based on light reception amounts; a switching element circuit array comprised of a plurality of switching elements for reading out the output signals from the light receiving elements; a scanning circuit array for driving the switching elements of the switching element circuit array; a common signal line connected to the plurality of switching elements for transmitting the output signals from the light receiving elements; an operational amplifier connected to the common signal line through a chip selection switch and operated by a single power supply under the GND power supply standard common to the image sensor for outputting the output signals to an image signal output terminal; and a reset switch connected to the common signal line; for supplying a reference voltage to the common signal line; wherein the reset switch and the switching elements turn ON to reset the light receiving elements to the reference voltage after reading out the output signals from the light receiving elements to the common signal line.
