1. An electronic device comprising:
at least one camera;
a depth sensor configured to obtain depth information about at least one object;
a memory storing one or more instructions; and
at least one processor configured to execute the one or more instructions to cause the electronic device to:
obtain, through the at least one camera, an image including at least one object in real world,
detect main object from the image obtained through the at least one camera,
determine a region of interest (ROI) corresponding to a region of the image including the main object,
set a measurement parameter of the depth sensor as a first parameter to obtain depth information for an entire region of the image including the ROI and a remaining region excluding the ROI,
obtain first depth information with a first resolution for the ROI by using the depth sensor with the first parameter,
adjust the measurement parameter of the depth sensor to a second parameter based on the first depth information, and
obtain second depth information with a second resolution for the ROI by using the depth sensor with the second parameter,
wherein the second resolution is higher than the first resolution, and
wherein the measurement parameter of the depth sensor comprises at least one of parameters with respect to the ROI for emitting light, parameters with respect to output of an emission light including an output pattern of the emission light and a magnitude of the output of the emission light of the depth sensor, or parameters with respect to sensing of a reflection light of the depth sensor including a sensing speed, a sensing period, or a sensing sensitivity.
