Apparatus for measuring bio-information, and electronic device including the same

A method of measuring bio-information, the method comprising:

• based on a pixel control signal or a timing signal which is generated by an image sensor, driving a first light emitter to emit first light of a first wavelength;
• detecting the first light of the first wavelength, which is reacted with an object, by using a plurality of first pixels included in a first pixel region of the image sensor;
• based on the pixel control signal or the timing signal which is generated by the image sensor, driving a second light emitter to emit second light of a second wavelength;
• detecting the second light of the second wavelength, which is reacted with the object, by using a plurality of second pixels included in a second pixel region of the image sensor;
• and
• measuring bio-information based on data obtained from the first and second pixel regions of the image sensor.

An apparatus for measuring bio-information, the apparatus comprising:

• a light source configured to emit first light of a first wavelength and second light of a second wavelength to an object;
• an image sensor comprising:
• a first pixel line comprising a plurality of first pixels which are exposed to the first light together at a first period of time;
• and
• a second pixel line comprising a plurality of second pixels which are exposed to the second light together at a second period time,
• a light source controller configured to control the light source to emit the first light during the first period of time, and control the light source to emit the second light during the second period time;
• and
• a processor configured to obtain the bio-information based on data collected from the first pixel line and the second pixel line of the image sensor.
