Abstract: An electronic apparatus is provided. The electronic apparatus according to the disclosure includes: a light emitter; a light receiver; a memory; and a processor, wherein the processor is configured to: acquire a first depth image based on first reflected light acquired 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 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 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 corresponding to time information on the second time period.
