There is provided a lighting fixture 11 capable of efficiently radiating heat of a lamp device 14 attached to a socket device 13. The up-sampling unit is configured to perform a joint bilateral up-sampling on depth information of a first input image based on a confidence map of the first input image and a second input image with respect to an object and increase a first resolution of the first input image to a second resolution to provide an output image with the second resolution. The perforation designs and patterns can be formed utilizing various mechanical perforating techniques. The twist of the shaft is converted into the movement in a direction to move the pistons by first and second levers, and the pistons are moved. The write strategy correcting unit may correct a write strategy based on the deviation and the previously-stored inherent variation.
