1. An electronic apparatus comprising:
a light emitter configured to emit light towards an area around the electronic apparatus as emitted light;
a light receiver configured to acquire reflected light from an object that reflects the emitted light emitted from the light emitter;
a memory storing one or more instructions; and
a processor configured to execute the one or more instructions to: acquire a first depth image based on first reflected light acquired through the light receiver during a first time period and store the first depth image in the memory,
acquire a second depth image based on second reflected light acquired through the light receiver during a second time period following the first time period, and
acquire distance information between the electronic apparatus and the object included in the second depth image by subtracting a first depth value of each pixel of the first depth image stored in the memory from a second depth value of each pixel of the second depth image, and correct the distance information by using a compensation value acquired based on time information corresponding to the second time period.
