1. A time of flight (ToF) sensor comprising:
a first light emitter configured to output first light having a first pattern;
a second light emitter configured to output second light having a second pattern;
an image sensor comprising a plurality of pixels; and
at least one processor configured to:
control the first light emitter and the second light emitter to sequentially output the first light and the second light,
obtain, based on the output first light and the output second light being received through the image sensor by being reflected by a plurality of objects, a first image frame corresponding to the received first light and a second image frame corresponding to the received second light,
identify distances between the ToF sensor and the plurality of objects based on the first image frame and the second image frame,
identify, based on a plurality of pixel values included in the first image frame, a first area corresponding to an object from among the plurality of objects in the first image frame, a first distance between the object and the ToF sensor being less than a pre-set distance,
determine an exposure time of the image sensor for the second light based on a plurality of first pixel values included in remaining areas excluding the first area in the first image frame, and
obtain, based on the second light being output through the second light emitter, the second image frame by receiving the second light reflected by the plurality of objects through the image sensor based on the exposure time.
