Abstract
An image sensor has light receiving elements, switching elements for reading out output signals from the light receiving elements, a scanning circuit array for driving the switching elements, and a common signal line connected to the switching elements for transmitting the output signals from the light receiving elements. An operational amplifier is connected to the common signal line through a chip selection switch and is 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. A reset switch is connected to the common signal line for supplying a reference voltage to the common signal line. 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.
