1. A projecting device configured to recognize an object with image projection, the projecting device comprising:
a light source configured to output an image light;
a projection lens configured to externally project the image light;
a camera configured to photograph an object positioned between the camera and an external projection surface of the image light that is projected;
a light blocker configured to block the image light output by the light source during a blocking period; and
at least one processor configured to control operations of the light source, the camera, and the light blocker,
wherein the at least one processor is further configured to:
obtain illuminance information regarding illuminance of the external projection surface,
set the blocking period during which the image light output by the light source is blocked, based on the illuminance information,
set a photographing period within the blocking period,
control the light blocker to block the image light output by the light source during the blocking period, and
control the camera to photograph the object during the photographing period.
