1. A method of estimating hemoglobin concentration, comprising:
receiving a skin image of a subject;
upon receiving the skin image, detecting from the skin image at least one region of interest including a body region of the subject where veins are visible;
converting color space of the at least one region of interest; and
calculating an average color value and an average saturation value with respect to the at least one region of interest;
determining a formula into which the skin image is introduced; and
estimating a hemoglobin concentration of the subject by introducing the skin image into the determined formula,
wherein the estimating the hemoglobin concentration of the subject including estimating the hemoglobin concentration by introducing at least one of the average color value and the average saturation value into the determined formula.
