Abstract
An eyeball-tilt detecting device for detecting a tilt position of an eyeball, including: a light source array including a plurality of light emitting sections that emit light having directivity; an optical spot position detection element configured to detect an optical spot position of light reflected from an eyeball to output a detection signal; and processing circuitry configured to calculate a tilt position of the eyeball based on the detection signal output from the optical spot position detection element.
