To enable performing pupil position detection having a low arithmetic load or low power consumption.SOLUTION: An eyeball detection apparatus according to the present invention comprises: an irradiation unit that irradiates almost parallel illumination light to a cornea of an eyeball； a detection unit that detects light intensity of reflected light from the cornea； and a detection control unit that calculates positional deviation of a cornea position relative to a reference optical axis after determining gravity center deviation in an angle direction relative to the reference optical axis, of the light intensity of the reflected light from the cornea on the basis of a detection value by means of the detection unit.SELECTED DRAWING: Figure 1【課題】演算負荷や消費電力の少ない瞳位置検出を行うことを可能にする。【解決手段】本開示の眼球検出装置は、略平行の照明光を眼球の角膜に向けて照射する照射部と、角膜からの反射光の光強度を検出する検出部と、検出部による検出値に基づいて角膜からの反射光の光強度の基準光軸に対する角度方向の重心偏りを判別した後、基準光軸に対する角膜位置の位置ずれを算出する検出制御部とを備える。【選択図】図１
