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.

Abstract: A semiconductor device that is less likely to be affected by a soft error is provided. The semiconductor device includes a first memory, a second memory, a processor that can be connected to the first memory and the second memory, and a selector for selectively connecting one of the first memory and the second memory to the processor. The probability of occurrence of a soft error of the first memory is higher than that of the second memory. When an error derived from a soft error is detected in the first memory, the selector connects the second memory to the processor. The semiconductor device can stably operate even when moved from an environment where a soft error is less likely to occur to an environment where a soft error is likely to occur.

Data that is necessary after the power supply is restarted can be backed up from the volatile register to the nonvolatile register before the power supply is stopped. Data that is unnecessary is not backed up from the volatile register to the nonvolatile register before the power supply is stopped.
