1. An apparatus for measuring bio-signals, the apparatus comprising:
a light source configured to emit light onto an object;
an image sensor comprising a pixel array configured to detect the light emitted by the light source and reacted by the object, the image sensor being configured to bin data of the light, detected by the pixel array, by using at least two different binning sizes; and
a processor configured to acquire a plurality of bio-signals respectively based on data of the at least two different binning sizes, the data of the at least two different binning sizes being output from the image sensor,
wherein the processor is further configured to acquire a first bio-signal using data of a first binning size in a first interval and acquire a second bio-signal using data of a second binning size in a second interval following the first interval, the first interval and the second interval being alternately repeated at a preset frame ratio, and
wherein the processor is further configured to independently obtain first bio-information using the first bio-signal, which is acquired based on the first binning size in the first interval, and obtain second bio-information using the second bio-signal, which is acquired based on the second binning size in the second interval, the first bio-information being a different type of bio-information than the second bio-information.
