Abstract: A skin treatment system including a treatment device to treat a treatment region of a body. The skin treatment system includes a camera to capture at least one image of skin, the image having an imaging region, and to provide captured image data representing the captured image. The imaging region has a predefined spatial relationship with the treatment region. The skin treatment system further includes a storage facility for storing reference image data indicative of a reference image of the skin. The skin treatment system further includes an orientation estimation facility to determine which part of the reference image corresponds to the at least one captured image, using the captured image data and the reference image data, and to derive from a predetermined orientation of said corresponding part with respect to the reference image, an orientation indication indicative of an orientation of the treatment device with respect to the body.

Abstract: A skin treatment system (1) is provided comprising a treatment device (10) to treat a treatment region (TR) of a mammal body (B) by physically acting upon the body in said treatment region. The skin treatment system further comprises a camera (20) to capture at least one image of skin of the mammal body, said image having an imaging region (IR), and to provide captured image data (Id) representative of the at least one captured image. The imaging region (IR) has a predefined spatial relationship with the treatment region. The skin treatment system (1) further comprises a storage facility (30) for storing reference image data (Ir) indicative of a reference image of the skin of the mammal body (B).
