1. A system for converting two dimensional video to three dimensional video, the system comprising: a processor having an input for receiving a two dimensional video data and an output for outputting three dimensional image data to a display; and the processor being configured to receive two dimensional video data comprising two dimensional images that are displayed in a sequential order over a period of time, segment a specific object in the two dimensional images based on variations in brightness in the two dimensional images to identify and locate the specific object in the two dimensional images, generate a depth map comprising depth values indicating object depth of the specific object in a two dimensional image among the two dimensional images, determine a depth value in the depth map for the specific object, adjust the depth value of the specific object over the period of time as a size of the specific object changes in each of the two dimensional images, and generate three dimensional video data comprising the specific object located according to the depth map, wherein the depth map comprises a combination of a row accumulated depth map and a column accumulated depth map.
