Methods, apparatus and systems that relate to a portable multispectral dermascope are described. An example dermascope includes light sources having different spectral contents and configured to illuminate an area of the skin and at least one imaging sensor configured to collect light that it receives from the area of the skin. The dermascope also includes a processor to control illumination provided by the light sources to the area of the skin and process information associated with received light from the area of the skin to produce images of the area of the skin. In the dermascope, illumination from the light sources is controlled to provide illumination in a plurality of distinct wavelengths or range of wavelengths that produce differing optical responses of the area of the skin. The described methods and devices can be used to identify skin conditions using a compact and convenient device, such as a mobile phone.
