Method and apparatus for evaluating skin condition

A method being performed by a computer, the method comprising:

• acquiring compressed image data obtained by compressing image information regarding part of a user's body for four or more wavelength bands into one image;
• generating, on the basis of the compressed image, a RGB image including a pixel value corresponding to a wavelength band of red light, a pixel value corresponding to a wavelength band of green light, and a pixel value corresponding to a wavelength band of blue light;
• causing a display device to display the RGB image;
• determining an evaluation region in the RGB image on the basis of an input from the user;
• generating, based on the compressed image data, partial-image data corresponding to at least one wavelength band among the four or more wavelength bands, the partial-image data corresponding to the part of the user's body, the partial-image data including data corresponding to the evaluation region;
• and
• generating, on the basis of the partial-image data, evaluation data indicating an evaluation result of skin condition in the evaluation region.
