摘要
An object of the present invention is to provide a solid-state image sensing device configured to change a bias voltage given to the photoelectric converting section at the time of resetting so that an operative condition of the photoelectric converting section after the resetting can be maintained a constant condition regardless of an amount of the incident light. To achieve the object, an MOS transistor T5 is provided. The drain of the MOS transistor T5 is connected with a gate and a drain of an MOS transistor T2 and the source of the MOS transistor T5configured to be applied a DC voltage VRS. Here, a signal Φ V is given, an MOS transistor T4is turned on, and image data is output. A signal Φ RS is given and the MOS transistor T5 is turned on. As a result, a gate voltage Vg of the MOS transistor T2 is maintained as a constant voltage value. Then, a reset operation for pixels is stared.
