METHOD AND APPARATUS FOR PROCESSING 3-DIMENSIONAL IMAGE

摘要

PURPOSE: A 3D image processing apparatus and a method thereof for improving SNR of the 3D image processing device by modulating the waveform of a transfer signal are provided to improve the depth precision of the 3D image by modulating the waveform of the emitted light. CONSTITUTION: A sensor unit(920) obtains a depth image according to the control of an image signal processor(910). The image signal processor comprises next. An ROI determiner(911) determines an interest region within the entire sensing region. A controller(913) controls an optical module in order to modulate the waveform of the emitted light. A depth information calculator calculates the depth from the depth image.
