1. A portable electronic device comprising:
a display;
a light source configured to radiate light to skin;
at least one light detector configured to detect light received from the skin;
at least one memory storing instructions;
a first polarization filter configured to filter the light radiated to the skin from the light source;
a second polarization filter configured to filter the light received from the skin by the at least one light detector; and
a processor configured to execute the instructions to:
control the light source to radiate the light,
analyzing the skin for wrinkles on a surface of the skin based on a depolarization ratio of the light detected by the at least one light detector, and
control the display to display a highlighting of the wrinkles based on analyzing the skin for the wrinkles,
wherein the light received from the skin comprises at least one of light scattered, light reflected, and light emitted by the skin,
wherein the second polarization filter is configured to, under the control of the processor, select a polarized component of the light received from the skin,
wherein the at least one light detector is further configured to detect light of the selected polarized component,
wherein the processor is further configured to execute the instructions to:
control the second polarization filter to select a polarized component in each of a same direction as and a direction perpendicular to the first polarization filter,
determine the depolarization ratio by comparing the polarized component in the same direction as the polarized light radiated to the skin and filtered by the first polarization filter with the polarized component detected by the at least one light detector in the direction perpendicular to the polarized light radiated to the skin and filtered by the first polarization filter, and
detect the wrinkles on the surface of the skin based on the depolarization ratio.
