1. An electronic device comprising:
a light source;
a light sensor; and
a controller configured to sense a coarse amount of ambient light by turning off the light source and performing sensing in a coarse mode by operating an analog-to-digital converter at a first resolution on data based on a first output from the light sensor and to sense a fine amount of the ambient light by performing sensing in a fine mode by operating the analog-to-digital converter at a second higher resolution on data based on a second output from the light sensor,
wherein the controller is configured to:
sense an amount of a target light by turning on the light source and performing sensing by using the light sensor while the light source emits a light; and
output information based on the coarse amount of the ambient light, the fine amount of the ambient light, and the amount of the target light.
