Abstract: An imaging device having a function of processing an image is provided. The imaging device has an additional function such as image processing, can hold analog data obtained by an image capturing operation in a pixel, and can extract data obtained by multiplying the analog data by a predetermined weight coefficient. Difference data between adjacent light-receiving devices can be obtained in a pixel, and data on luminance gradient can be obtained. When the data is taken in a neural network or the like, inference of distance data or the like can be performed. Since enormous volume of image data in the state of analog data can be held in pixels, processing can be performed efficiently.

Abstract: A semiconductor device capable of holding analog data is provided. Two holding circuits, two bootstrap circuits, and one source follower circuit are formed with use of four transistors and two capacitors. A memory node is provided in each of the two holding circuits; a data potential is written to one of the memory nodes and a reference potential is written to the other of the memory nodes. At the time of data reading, the potential of the one memory node is increased in one of the bootstrap circuits, and the potential of the other memory node is increased in the other of the bootstrap circuits. A potential difference between the two memory nodes is output by the source follower circuit. With use of the source follower circuit, the output impedance can be reduced.
