Abstract: An ultrathin camera device is provided. The ultrathin camera device comprises an optical module including a microlens array in which microlenses are arranged, an image sensor that outputs electrical image signals by sensing light coming through the microlens array, spacers that form a focal length by separating the optical module from the image sensor, and a processor that outputs a final image by reconstructing array images generated from the image signals with a designated imaging process depending on a distance at which the object is located. Here, each microlens convexly protrudes toward the image sensor.
