<P>PROBLEM TO BE SOLVED: To provide an eyeball movement measuring device highly precisely measuring both of a gentle movement and a high-speed movement of the eyeball according to the moving speed. <P>SOLUTION: This eyeball movement measuring device 1 is provided with an imaging part 3 having a light detecting part 31 including a plurality of pixels 31a and creating image data S<SB>2</SB>related to cornea reflected light images L2 incident on the light detecting part 31; and an imaging form setting means 55 setting a resolution and an imaging area of the light detecting part 31 based on the moving speed of the incident position of the cornea reflected light image L2 calculated based on the imaging data S<SB>2</SB>. When the moving speed of the cornea reflected light image L2 is relatively high, this constitution allows to lower the resolution and set the imaging area wide and, when the moving speed of the cornea reflected light image L2 is relatively low, allows to raise the resolution and set the imaging area narrow, thus highly precisely measuring the both of the gentle movement and the high-speed movement of the eyeball 21 according to the moving speed. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
