The present invention relates to a distance detection apparatus for acquiring distance information having variable spatial resolution and an image display apparatus having the same. A distance detection apparatus according to an embodiment of the present invention comprises a light source unit for outputting an output light to detect a distance to an external object, a scanner for performing first direction scanning and second direction scanning to output an output light to an external scan area, a light detection unit for receiving an input light from the scan area, and a processor for detecting a distance to an external object within the external scan area on the basis of the output light and the input light, wherein the processor makes a control to change a frame rate of the scanner and acquires distance information having varied spatial resolution of the external object in accordance with the change in the frame rate. Accordingly, it is possible to acquire distance information having variable spatial resolution on an external object.

Distance detection apparatus for acquiring distance information having variable spatial resolution and image display apparatus having the same

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.
