Abstract
A system for analyzing at least one characteristic of the skin (1) and by extension hair, via optics (7, 4) and image processing (4, 5) elements notably include a consumer electronics device (4). The method for analyzing at least one characteristic of the skin notably includes a step wherein at least one digital image is acquired via a consumer electronics device. According to a first aspect, the method notably aims at applications in the field of cosmetics or that of skin cancer screening, and according to a second aspect in the field of assisting with diagnosis of allergies.
Claims29
A system for analyzing a characteristic of skin, comprising:
- a consumer electronics device comprising an objective and configured to i) digitally acquire an image of the skin from light reflected off skin being imaged, and ii) produce data representing the acquired image of the skin;
- a first device comprising i) a first region to be placed at a distance between 0 and 50 mm of the skin being imaged, ii) a second region opposite the first region in a light path of the light reflected off the skin being imaged by the consumer electronics device, second region being placed at a distance between 0 and 2 meters of the objective of the consumer electronics device, the first device being placed in the optical axis of the objective of the consumer electronics device to allow the consumer electronics device to acquire the image the skin, and iii) an optical magnification element, distinct of the objective of said consumer electronics device, positioned in the light path between a) first region of the first device, and b) the second region of the first device, including the limits, the optical magnification element configured to optically bend or focus the light in the light path, before the light reaches the objective and the image is acquired by the consumer electronics device, the optical magnification element producing a global optical magnification of the image at a level suitable for analyzing the skin based on the data produced by the consumer electronics device;
- and
- a digital image processing device operatively connected to said consumer electronics device to i) receive said produced data of the acquired image of the skin, said produced data of the skin including data relating to additional visible information included in the image, and ii) process the received data of the acquired image of the skin to produce information in relation to at least one characteristic of the skin.
