PROBLEM TO BE SOLVED: To obtain an individual body identifying device by which an individual body can be correctly identified by preventing whether a picture is focused or not from being erroneously judged by reflection. SOLUTION: The individual body identifying device 10 includes a luminance difference calculating part 12 for selecting plural groups of pixels consisting of two adjacent pixels from among plural pixels in a picture which is obtained by a picture obtaining part 11 and calculating the luminance difference of the two pixels in every group, a counting part 13 for counting the number of groups where a value based on luminance difference which is calculated by the part 12 becomes larger than a first prescribed value and a judging part 14 for judging that the picture is focused in case the number counted by the counting part 13 is larger than the second prescribed value. |
