Description
本実施形態において、撮像装置４の撮像データは、フレーム毎の画像６０を示す画像データである。制御部５２は、フレーム毎の画像６０における瞳孔６１の位置の時間的変化を抽出する（Ｓ１２）。これにより、フレーム画像６０のフレームレートの範囲内で、瞳孔６１の動きの時間周波数解析を行うことができる（図６）。
In the present embodiment, the image pickup data of the image pickup device 4 is image data showing the image 60 for each frame. The control unit 52 extracts the temporal change of the position of the pupil 61 in the image 60 for each frame (S12). Thereby, the time-frequency analysis of the movement of the pupil 61 can be performed within the range of the frame rate of the frame image 60 (FIG. 6) .
