Abstract
An imaging device includes a first memory configured to perform writing to multiple addresses thereof by designating the multiple addresses on address-by-address basis, a second memory configured to perform writing simultaneously to multiple address thereof, and a control circuit that controls readout of signals from the first memory and the second memory. The control circuit is configured to perform a first operation mode to sequentially designate the multiple addresses of the first memory and sequentially perform readout of signals from the multiple addresses of the first memory, and a second operation mode to sequentially designate the multiple addresses of the second memory and sequentially perform readout of signals from the multiple addresses of the second memory so that an output value from the second memory becomes the same as a value expected as an output value from the first memory in the first operation mode.
