A mobile terminal, comprising: a camera; a lighting device comprising a pattern light source and a surface light source, wherein the pattern light source is configured to emit light having a defined pattern and the surface light source is configured to emit uniform light; and a controller configured to: cause the camera to capture a 3D image; and control the lighting device to cause the pattern light source and the surface light source to alternately emit light, in association with the capturing of the 3D image, wherein the controller is further configured to: cause the pattern light source to activate to emit light when the camera captures a first frame for the 3D image; and cause the surface light source to activate to emit light when the camera captures a second frame for the 3D image that is captured after the capturing of the first frame, characterized in that the pattern light source includes a plurality of light emitting devices that are grouped into a plurality of groups (1110, 1120, 1130, 1140, 1150, 1160, 1170, 1180, 1190), wherein the controller is further configured to sequentially activate the groups of light emitting devices to emit light on a group by group basis and in a defined order, thereby defining a single set during which all of the plurality of groups are sequentially lit on, and when the camera captures the first frame the controller controls the lighting device so that the single set in which all of the plurality of groups sequentially emit light in the predetermined order is performed a plurality of times, wherein a time during which the single set is performed is constant, so that the number of times the single set is performed while the first frame is being captured varies depending on a time during which the first frame is captured, and the number of times the single set is performed while the first frame is being captured decreases as the time during which the first frame is captured decreases and increases as the time during which the first frame is captured increases. a camera; a lighting device comprising a pattern light source and a surface light source, wherein the pattern light source is configured to emit light having a defined pattern and the surface light source is configured to emit uniform light; and a controller configured to: cause the camera to capture a 3D image; and control the lighting device to cause the pattern light source and the surface light source to alternately emit light, in association with the capturing of the 3D image, cause the camera to capture a 3D image; and control the lighting device to cause the pattern light source and the surface light source to alternately emit light, in association with the capturing of the 3D image, wherein the controller is further configured to: cause the pattern light source to activate to emit light when the camera captures a first frame for the 3D image; and cause the surface light source to activate to emit light when the camera captures a second frame for the 3D image that is captured after the capturing of the first frame, characterized in that the pattern light source includes a plurality of light emitting devices that are grouped into a plurality of groups (1110, 1120, 1130, 1140, 1150, 1160, 1170, 1180, 1190), cause the pattern light source to activate to emit light when the camera captures a first frame for the 3D image; and cause the surface light source to activate to emit light when the camera captures a second frame for the 3D image that is captured after the capturing of the first frame, characterized in that the pattern light source includes a plurality of light emitting devices that are grouped into a plurality of groups (1110, 1120, 1130, 1140, 1150, 1160, 1170, 1180, 1190), wherein the controller is further configured to sequentially activate the groups of light emitting devices to emit light on a group by group basis and in a defined order, thereby defining a single set during which all of the plurality of groups are sequentially lit on, and when the camera captures the first frame the controller controls the lighting device so that the single set in which all of the plurality of groups sequentially emit light in the predetermined order is performed a plurality of times, wherein a time during which the single set is performed is constant, so that the number of times the single set is performed while the first frame is being captured varies depending on a time during which the first frame is captured, and the number of times the single set is performed while the first frame is being captured decreases as the time during which the first frame is captured decreases and increases as the time during which the first frame is captured increases.
