Provided is a device for driving first and second electrodes and an electro-optical element including a material having optical characteristics that vary with an applied voltage. The device includes: a driving unit which drives the electro-optical element between first and second driving states; a display unit which displays an image based on the optical characteristics of the electro-optical element; a pickup unit that outputs image data according to the amount of incident light; a first memory which fetches/stores the image data as reference image data; a second memory which fetches/stores the image data as target image data; a difference image data generating unit which generates difference image data from a difference between the reference and target image data; and a control unit which controls the write/read of the first and second memories such that the driving states corresponding to the reference image data and the target image data become equal.
