Abstract: An imaging device capable of image processing is provided. The imaging device can retain analog data (image data) obtained by an image-capturing operation in a pixel and perform a product-sum operation of the analog data and a predetermined weight coefficient in the pixel to convert the data into binary data. When the binary data is taken in a neural network or the like, processing such as image recognition can be performed. Since enormous volumes of image data can be retained in pixels in the state of analog data, processing can be performed efficiently.

Abstract: The present invention relates to a highly functional imaging device that can be manufactured through a small number of steps. The imaging device is formed in such a manner that a first stacked body in which a plurality of devices are stacked and a second stacked body in which a plurality of devices are stacked are bonded to each other. For example, a pixel circuit, a driver circuit of a pixel, and the like can be provided in the first stacked body, and a reading circuit of the pixel circuit, a memory circuit, a driver circuit of the memory circuit, and the like can be provided in the second stacked body. With these structures, the imaging device which is small can be formed. Furthermore, wiring delay or the like can be prevented by stacking circuits, so that high-speed operation can be performed.

Abstract: An imaging device that has an image processing function and is capable of a high-speed operation is provided. The imaging device, which has an additional function such as image processing, can retain analog data obtained by an image capturing operation in a pixel and extract data obtained by multiplying the analog data by a predetermined weight coefficient. In the imaging device, some of potentials used for an arithmetic operation in pixels are generated by redistribution of charge with which wirings are charged. This enables an arithmetic operation to be performed at high speed with low power consumption, compared with the case where the potentials are supplied from another circuit to the pixels.

Abstract: An imaging system that has an image processing function and is capable of generating an interpolation image is provided. The imaging system has an additional function such as image processing and can generate an interpolation image by using image data output from an imaging device. The imaging device can perform filter processing in parallel during a light exposure period, and thus can perform a large amount of arithmetic operation and generate a high-quality interpolation image. The number of arithmetic operations can be further increased particularly during image capturing in a dark place, which requires a long exposure time. Accordingly, the frame rate can be substantially increased, and high-quality moving image data can be generated.

Abstract: An imaging device capable of executing image processing is provided. Analog data (image data) acquired through an imaging operation is retained in a pixel, and data obtained by multiplying the analog data by a given weight coefficient in the pixel can be extracted. The data is taken into a neural network or the like, whereby processing such as image recognition can be performed. Since an enormous amount of image data can be retained in pixels in an analog data state, processing can be performed efficiently.

Abstract: An imaging device having a motion detecting function and an image processing function is provided. The imaging device can detect a difference between a reference frame image and a comparative frame image, and can switch from a motion detecting mode to a normal image capturing mode when a significant difference is detected. A low-frame-rate operation in the motion detecting mode can reduce power consumption. Moreover, the imaging device has an image recognition function in combination with the motion detecting function, so that switching from the motion detecting mode to the normal image capturing mode can be performed when a particular image is recognized.
