In this study, we demonstrate that a self-reset image sensor is capable of detecting weak intensity changes as small as 0.1%. The self-reset image sensor achieves a high signal-to-noise ratio by avoiding pixel saturation and detecting several million electrons. In the demonstration experiment, small intensity changes were generated using two light sources with different intensities, and measurements were performed using a self-reset image sensor. These results indicate that the proposed sensor is promising for application to brain functional imaging using voltage-sensitive dyes.
