Camera device

A camera device comprising:

• a light emitter which emits light signals having a predetermined pattern to an object;
• a light receiver which receives light signals reflected by the object;
• a depth map generator which generates a depth map of the object using the light signals input to the light receiver;
• and
• a controller which controls the light emitter, the light receiver, and the depth map generator,
• wherein the light emitter includes a plurality of light sources including a first light source and a second light source,
• the light receiver includes an image sensor,
• the first light source and the second light source are symmetrically disposed with the image sensor interposed therebetween,
• the first light source outputs first light signals having a first pattern formed of a plurality of dots,
• the second light source outputs second light signals having a second pattern formed of a plurality of dots,
• the image sensor includes a first region in which both of the plurality of dots forming the first pattern and the plurality of dots forming the second pattern are received and a second region in which the plurality of dots forming the first pattern or the plurality of dots forming the second pattern are received,
• the plurality of dots forming the first pattern and the plurality of dots forming the second pattern do not overlap each other in the first region, and
• the depth map generator generates the depth map based on light signals received in the first region.
