PROBLEM TO BE SOLVED: To correctly detect nail information, by only imaging an imaging object from one direction.SOLUTION: A nail information detection device comprises: an imaging part 30 for acquiring a nail image; a movement part for relatively moving the imaging part to the nail; and a control part 51 for detecting the nail information from the nail image acquired by the imaging part 30. The control part 51 detects an end of an acquired first nail image in a width direction, as a first end part, in a state that first positioning for matching a nail vertex position is performed so as to be made match a reference position of an imaging range of the imaging part 30 in a width direction. The control part 51 detects a second end part corresponding to an end of the nail in a width direction, based on the acquired second nail image, in a state that second positioning for matching the reference position of the imaging range of the imaging part 30 to one of the first end part and an end of the nail in a width direction, is performed. The control part 51 detects height of the nail vertex position from the second end part, based on positions of the first end part and second end part, and imaging distance.SELECTED DRAWING: Figure 6 |
