Abstract: Disclosed are an array camera, an electrical device, and a method for operating the same. A method for operating an array camera including a plurality of camera modules includes acquiring images through the camera modules, when a first object is located at a first position of a first distance, extracting a first image and a second image acquired by a first camera module and a second camera module selected from among the camera modules, respectively, calculating distance information regarding the first object based on the first image and the second image, and when a second object is located at a second position or a second distance, calculating distance information regarding the second object located at the second position or the second distance based on at least one of a third image acquired by a camera module different from the first camera module and a fourth image acquired by a camera module different from the second camera module. Consequently, user convenience is improved.

Abstract: An image printing device using a display device according to an embodiment of the present invention comprises: a light collecting device for substantially focusing light output from the display device on a screen of the display device in a vertical direction; and a photographic paper which is located on the light collecting device and is photosensed by light provided from the display device through the light collecting device so that an image displayed on the display device is formed, wherein movement of the photographic paper provided in the image printing device is controlled by an external control device in which the display device is mounted, so that an image displayed on the display device can be formed in the photographic paper provided in the image printing device.
