An electronic apparatus capable of estimating the inclination of a head with a unit which is different from a unit like an acceleration sensor which directly detects the inclination of a housing and reflecting the inclination in the display is provided. The electronic apparatus includes an imaging device for detecting movement of an eyeball, a sight line detection device for detecting movement of a sight line on the basis of data obtained with the imaging device, an arithmetic device for performing an operation on display data based on the movement of the sight line, and a display device for performing display based on the display data. The electronic apparatus can estimate the inclination of a head with a unit which is different from a unit which is different from a unit like an acceleration sensor which directly detects the inclination of a housing and reflect the inclination in display.
