Abstract
(EN)
A camera device according to an embodiment of the present invention includes: a light output unit which outputs output light signals to be emitted to an object and includes a plurality of light sources arrayed according to prescribed rules; a lens unit which includes an infrared (IR) filter and at least one lens disposed on the IR filter, and focuses input light signals reflected from the object; an image sensor which generates electrical signals from the input light signals focused by the lens unit; an image processing unit which acquires depth information about the object by using phase differences or time differences between the output light signals and the input light signals received in the image sensor; and a control unit which controls the light output unit, the lens unit, the image sensor, and the image processing unit, wherein the plurality of light sources are divided into at least two light source groups, the control unit controls the output light signals to be output sequentially for each light source group, the image sensor includes at least two pixel groups divided for each of the light source groups, and the control unit controls the input light signals to be focused sequentially for each pixel group.
