Electronic device for the automated painting and drying of fingernails, that allows the user to choose the color they want to paint the nails as well as to carry the device due to its light weight. In one embodiment, the device has a sensor that identifies the hand that has been introduced in it, a touch LED screen, which allows the user to choose the nail and color with which to paint it, without the need for specialized personnel to operate it, as well as to inform the user through visible and audible means the process taking place. In one embodiment, the unit contains capacitive and/or infrared sensors to locate and detect the difference of the surface of the finger and nail, a computer or processor which guides and controls the gimbaled paint head with the ink that carries the staining of the surface of the nail.

A contour detection apparatus includes a processor. The processor learns to detect a nail contour being a detection target by setting an initial shape including feature points based on learning data each being image data on a finger including a learning target nail, and setting, as a reference point, a feature point among the feature points corresponding to a reference position, thereby obtaining contour detection information. The processor arranges, in treatment target data being image data on a finger including a treatment target nail, an initial position of the shape such that a point corresponding to the reference position in a contour of the finger including the treatment target nail is superposed on the reference point, and fits the shape to the treatment target nail from the initial position, thereby detecting the nail contour of the treatment target nail.

The present invention relates to the field of nail grooming and generally describes a novel nail-grooming device whose purpose is to allow a user to groom his or her own fingernails in both hands in an accurate, symmetrical and uniform manner, with minimal effort and without being required to acquire any skills that might be required by other devices. The device comprises a finger placement wherein a user places his or her finger, and a nail grooming machine with a nail grooming head suitable for nail grooming tasks such as filing, wherein the nail grooming head is capable of performing a cyclic movement against a nail of the finger placed on the finger placement for filing or other nail-grooming task, and wherein the nail filing machine also comprises a mechanism capable of triggering a sideways movement of the nail grooming head on a curved horizontal axis around the nail to allow circumferential grooming of the fingernail while the finger is statically placed on the finger placement.
