An imaging device 1 is configured to include an imaging element 10 and a DSP 20. The imaging element 10 includes a sensor register 13 that stores imaging control information, and the DSP 20 includes a mirror register 25 having a configuration equivalent to that of the sensor register 13. A system controller 23 controls such that identical imaging control information is stored in the sensor register 13 and the mirror register 25, and a timer section 29 is configured such that, in response to timer events generated with a period of a time interval T1, the imaging control information stored in the mirror register 25 is transmitted to the imaging element 10, thereby refreshing the sensor register 13.
