PROBLEM TO BE SOLVED: To provide a blink detection method and device for determining a blinking state of a user based on a continuous image.SOLUTION: After acquiring an eye image sequence of a user, a present detection image and a previous picked-up image are acquired from the eye image sequence, and reflection regions of the present detection image and the previous picked-up image are filtered. A luminance value of a pixel contained in the reflection region is higher than a luminance threshold. A different pixel amount between the present detection image and the previous picked-up image is calculated and based on the difference pixel amount, it is determined whether blinking is done by the user or not.SELECTED DRAWING: Figure 2【課題】連続画像に基づいて使用者の瞬き状態を判断する瞬き検出方法および装置を提供すること。【解決手段】使用者の眼画像列を取得した後、眼画像列から現検出画像および前撮像画像を取得し、現検出画像および前撮像画像の反射領域をフィルタリングする。反射領域に含まれる画素の輝度値は、輝度しきい値よりも高い。現検出画像と前撮像画像の間の相違画素量を計算し、相違画素量に基づいて、使用者が瞬きしたかどうかを判断する。【選択図】図2
