Method of analysing at least one parameter of a body component is provided. The method includes illuminating the component or body with light of at least a first and second waveband, receiving light of at least said first and second wavebands remitted by the component at a photoreceptor or photoreceptors, and analysing the light received at the photoreceptor(s) to provide a ratio between the amount of light remitted of the first waveband and the amount of light remitted of the second waveband, and from this calculating the component parameter.

Method and apparatus for quantifying tissue histology

An image of an individual () is obtained using a digital camera (). The image data is then processed by ratio determination module () and an image conversion module () to analyze the image and determine data representative of the distribution of blood and melanin in the skin of the imaged individual. This chromophore distribution data is then processed by an image generation module () which generates an image representative of the expected appearance of epithelial tissue having the determined distribution of chromophores where the epithelial tissue is under fixed illumination and has a flat spatial geometry and where all the identified melanin is present solely in the epidermis. The presence of dermal melanin can then be identified by comparing the original image data and the image derived from processing the calculated chromophore distributions and identifying where the ratio of these images differs by more than a threshold, the threshold being set at a level above the amount of variation expected due to lighting and geometry differences.

Method and apparatus for detecting the presence of dermal melanin in epithelial tissue

An image of an individual () is obtained via a digital camera (). The RGB image data is then processed to derive from the image data data representative of the distribution of chromophores resulting in the appearance of the individual (). A calculated chromophore distribution is then utilised to derive a revised chromophore distribution representing the effect of the desired cosmetic or surgical intervention or medical condition. This chromophore distribution is then processed to generate an output image () illustrating the expected result of that intervention. The generated image () can be displayed simultaneously with an original image () so that the extent of expected improvement can be determined.
