We have fabricated a vision sensor with in-pixel non-volatility analog memory using a c-axis aligned crystalline oxide semiconductor FET that demonstrates very low off-state current. The pixel is possible to retain not only capturing image data but also differential image data of a given reference flame for a long time. Thus, the vision sensor can realize normal image capturing and extracting a differential image by an electronic global shutter, and motion capturing by judging the presence or absence of differences. Furthermore, it has three modes of operations, and can reduce power consumption by power gating idling blocks in each mode. |
