DISTANCE DETECTION APPARATUS FOR ACQUIRING DISTANCE INFORMATION HAVING VARIABLE SPATIAL RESOLUTION AND IMAGE DISPLAY APPARATUS HAVING SAME

摘要

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.
