Abstract: The present invention relates to an accessory device (20) for an image-capturing device (10) for capturing a skin image of a subject's skin comprising a tubular member (21) having a first opening (22) at its first end (23) configured to surround a light source (11) and an image sensor (12) included in the image-capturing device (10) and a second opening (24) at its second end (25) configured to surround a skin portion (101) and two mirrors (26, 27) arranged within the tubular number (21) at its second end (25), wherein a first mirror (26) is arranged to retied light (30) emitted by the light source (11) towards the skin portion (101) and a second mirror (27) is arranged to reflect light (31) reflected from the skin portion (101) towards the image sensor (12). The accessory device can be coupled to an image-capturing device to acquire an image of a skin portion, which is evaluated to determine a skin parameter, such as skin gloss.

Abstract: According to an aspect, there is provided a method of displaying a guidance indicator to a user. The method comprises receiving a series of images of a head of a user; determining, from each image of the series of images, information relating to the position of the head of the user; and displaying to the user, on a display screen, a guidance indicator associated with a representation of the head of the user only if each of one or more defined conditions regarding the position of the head is met. According to other aspects, an apparatus is also provided.
