Abstract
Claims
1. A hair removal device that performs hair removal using a beam of light emitted from a light source, comprising: a light source; a beam diameter control unit capable of changing the beam diameter of the beam of light emitted onto a treatment area of the skin; and an irradiation position identification unit that identifies the irradiation position of the beam of light in the treatment area using the beam diameter of the beam of light set by the beam diameter control unit, wherein the beam diameter control unit is configured to selectively set the beam diameter of the beam of light emitted onto the treatment area to at least a first beam diameter and a second beam diameter smaller than the first beam diameter, and the irradiation position identification unit comprises a first irradiation position identification unit that identifies the irradiation position of the beam of light at the first beam diameter and a second irradiation position identification unit that identifies the irradiation position of the beam of light at the second beam diameter.
2. The hair removal apparatus according to claim 1, wherein the first irradiation position identification unit identifies a predetermined area including a plurality of hair follicles in the area to be treated as the irradiation position of beam light with a first beam diameter, and the second irradiation position identification unit identifies each hair follicle in the area to be treated as the irradiation position of beam light with a second beam diameter.
3. A hair removal device according to claim 1 or 2, comprising: an imaging unit capable of imaging the area to be processed; and a beam diameter determination unit that, based on image data of the area to be processed captured by the imaging unit, identifies the average distance between hair follicles or the density of hair follicles in the area to be processed, and selects either the first beam diameter or the second beam diameter based on the identified average distance between hair follicles or density of hair follicles.
4. The hair removal apparatus according to claim 3, further comprising a display panel capable of displaying the determination result of the beam diameter determination unit, and a selection button capable of selecting either the first beam diameter or the second beam diameter.
5. The hair removal apparatus according to claim 3, wherein the beam diameter control unit sets the beam diameter of the beam light irradiated onto the processing target area to either the first beam diameter or the second beam diameter based on the determination result of the beam diameter determination unit.
6. The hair removal device according to claim 1 or 2, wherein the first irradiation position identification unit identifies a predetermined region as the irradiation position that does not overlap with the predetermined region identified as the irradiation position during the previous irradiation.
7. The hair removal apparatus according to claim 1 or 2, comprising an adjustment lens for adjusting the beam diameter of the beam light emitted from the light source, wherein the beam diameter control unit is configured to change the beam diameter of the beam light irradiated onto the area to be treated by moving the light source and the adjustment lens closer together or further apart from each other.
8. The hair removal apparatus according to claim 1 or 2, comprising a light source control unit for controlling the light source, wherein the light source control unit is configured to adjust the emission interval of beam light emitted from the light source based on the beam diameter of the beam light set by the beam diameter control unit.
9. A hair removal method comprising a beam light emitted from a light source, the method comprising: a beam diameter control step that can change the beam diameter of the beam light emitted to a treatment area of the skin; and an irradiation position identification step that identifies the irradiation position of the beam light in the treatment area using the beam diameter of the beam light set by the beam diameter control step, wherein the beam diameter control step comprises a step of selectively setting the beam diameter of the beam light emitted to the treatment area to at least a first beam diameter and a second beam diameter smaller than the first beam diameter, and the irradiation position identification step comprises a first irradiation position identification step that identifies the irradiation position of the beam light at the first beam diameter and a second irradiation position identification step that identifies the irradiation position of the beam light at the second beam diameter.
