An electronic camera is provided with a touchscreen. When a cameraman touches the touchscreen on a principal subject in a captured image shown on the touchscreen, the touched portion is determined and the focus and exposure are adjusted in conformity with the principal subject. When the image is designated to be stored, positional information on the principal subject as well as image information is stored into a built-in memory or a detachable external memory. For this reason, wherever the principal subject is located on the image, the image-capturing is performed with favorable results. The positional information on the principal subject is utilized for printing or reproducing the image so as to perform image tone corrections such as correction of brightness and skin pigmentation in an area including the principal subject, so that a high-quality image can be printed or reproduced.

Methods and apparatus are described that provide the ability to estimate the diffuse reflection component of an image of tissue such as skin captured without cross-polarization. It is thereby possible to estimate skin pigmentation information from an image of skin captured conventionally, such as, for example, a total reflection image, obtained in a conventional manner by shining white light on the skin and capturing the reflected light. The image may also be a partially diffuse reflection image, such as a low quality cross-polarized image. The diffuse reflection component of a captured image can then be further processed to obtain Red and Brown pigmentation images, useful for indicating the distribution of hemoglobin and melanin, the primary chromophores of skin. Additionally, a standard captured image of skin can be analyzed to obtain an estimate of the surface reflection component of the reflected light. The surface reflection component can then be used to generate a surface reflection image, useful for showing the distribution of light on the skin and to highlight superficial features such as wrinkles, fine lines, folds, pores, texture, and visible spots.
