The present invention relates to a device for detecting distance and an apparatus for processing images comprising same. The device for detecting distance according to one embodiment of the present invention, comprises: a light source portion for outputting an output light based on a plurality of transmission signals having different frequencies; a scanner for sequentially scanning in a first direction and then a second direction to output the output light into an external area; a detection portion for converting received light, which corresponds to the output light and is received from the outside, into reception signals; and a processor for calculating distance to an external object and varying the frequency of the transmission signals, based on the plurality of transmission signals and the plurality of reception signals, wherein the processor calculates a first distance to the external object based on a first transmission signal from among the plurality of transmission signals and a first reception signal corresponding to the first transmission signal, calculates a second distance to the external object based on a second transmission signal from among the plurality of transmission signals and a second reception signal corresponding to the second transmission signal, and calculates a final distance to the external object based on the first and second distances that have been calculated. As a result, the distance to the external object can be accurately detected.

An LED having vertical topology and a method of making the same is capable of improving a luminous efficiency and reliability, and is also capable of achieving mass productivity. The method includes forming a semiconductor layer on a substrate; forming a first electrode on the semiconductor layer; forming a supporting layer on the first electrode; generating an acoustic stress wave at the interface between the substrate and semiconductor layer, thereby separating the substrate from the semiconductor layer; and forming a second electrode on the semiconductor layer exposed by the separation of the substrate.

A travel route searching method of a mobile object whereby a travel route preferred by a user of a mobile object is searched using a road preferred by the user of the mobile object, a travel pattern at a crossroad and a road recommended by other user, and wherein the method comprises the steps of: collecting information of a road traveled by the mobile object, and discriminating a road preference by the collected information of the road to search the travel route; collecting a behavioral factor of the mobile object at a crossroad, and discriminating a behavioral factor preference of the user by the collected behavioral factor to search the travel route; storing as a recommended road the information of the road the mobile object has traveled if there is a instruction of storing the recommended road; and searching a recommended road situated between a starting point and a destination if the travel route is searched. Preference of the user relative to roads, a travel pattern preferred by the user and a recommended route are selectively used for the search of the travel route by the user.
