<P>PROBLEM TO BE SOLVED: To provide a glasses determination device and the like capable of precisely determining reflection light, which is reflected in an eye image by glasses, with a few restrictions on lighting light. <P>SOLUTION: A glasses determination part 31 is provided with a histogram generation part 311 generating a histogram about a luminance value of the eye image, a histogram memory 312 storing the generated histogram, a first comparison part 313 finding a difference between a frequency of each luminance value and a frequency of a luminance value smaller than that by one about the generated histogram for comparing dimension relationship between the difference and a first threshold value, a second comparison part 314 finding a difference between a frequency of each luminance value and a frequency of a luminance value smaller than that by one about the generated histogram for comparing dimension relationship between the difference and a second threshold value, and a determination part 315 determining whether the reflection light by the glasses is included in the eye image or not from the comparison result by the first and second comparison parts 313 and 314. <P>COPYRIGHT: (C)2007,JPO&INPIT |
