Drawing apparatus and drawing method for drawing apparatus

A drawing method for a drawing apparatus, the drawing apparatus comprising a processor and a drawing mechanism configured to perform drawing on a nail of an object being a finger or a toe, the drawing method being performed under control of the processor, and the drawing method comprising:

• acquiring a first captured image of the nail and a second captured image of the nail, the first captured image and the second captured image being images captured from a first direction by an imaging device located at a position along the first direction from a first location of a surface of the nail, the first direction being a direction along an optical axis of the imaging device, the first captured image being an image captured by the imaging device in a state where a distance along the first direction between the imaging device and the first location of the surface of the nail is a first distance, and the second captured image being an image captured by the imaging device in a state where a distance along the first direction between the imaging device and the first location of the surface of the nail is a second distance different from the first distance;
• and
• acquiring a value of a width of the nail at the first location of the surface of the nail based on a distance obtained from each of the first captured image and the second captured image along a width direction of the nail, the distance being a distance between a first surface position of the surface of the nail along the optical axis of the imaging device, and an edge of the surface of the nail along the width direction of the nail from the first surface position.

A drawing apparatus, comprising;

• a drawing mechanism configured to perform drawing on a nail of an object being a finger or a toe;
• a non-movable camera located at a position along a first direction from a first location of a surface of the nail, the non-movable camera being configured to capture an image of the nail;
• a receiving portion comprising a plate member configured to selectively support the object, when the object is received in the receiving portion, at one of a first position at which the first location of the surface of the nail is at a position where a distance along the first direction between the first location of the surface of the nail and a preset reference position has a first value, and a second position where the first location of the surface of the nail is at a position where the distance along the first direction between the first location of the surface of the nail and the preset reference position has a second value different from the first value;
• and
• a processor,
• wherein the processor:
• acquires a first captured image of the nail and a second captured image of the nail, the first captured image being an image captured by the camera in a state where a distance along the first direction between the camera and the first location of the surface of the nail is a first distance, and the second captured image being an image captured by the camera in a state where a distance along the first direction between the camera and the first location of the surface of the nail is a second distance different from the first distance;
• and
• acquires a value of a width of the nail at the first location of the surface of the nail based on the first captured image and the second captured image.
