摘要： An imaging device with low power consumption is provided. It includes a pixel capable of outputting difference data between two different frames, a circuit determining the significance of the difference data, a circuit controlling power supply, an A/D converter, and the like; obtains image data and then obtains difference data; and shuts off power supply to the A/D converter and the like in the case where it is determined that there is no difference, and continues or restarts the power supply to the A/D converter and the like when it is determined that there is a difference. Determining the significance of the difference data can be performed row by row in a pixel array or at nearly the same time in all the pixels included in the pixel array.

摘要： Data of a register in a programmable logic element is retained. A volatile storage circuit and a nonvolatile storage circuit are provided in a register of a programmable logic element whose function can be changed in response to a plurality of context signals. The nonvolatile storage circuit includes nonvolatile storage portions for storing data in the register. The number of nonvolatile storage portions corresponds to the number of context signals. With such a structure, the function can be changed each time context signals are switched and data in the register that is changed when the function is changed can be backed up to the nonvolatile storage portion in each function. In addition, the function can be changed each time context signals are switched and the data in the register that is backed up when the function is changed can be recovered to the volatile storage circuit.
