Title:
IMAGE PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2018/139237
Kind Code:
A1
Abstract:
The present invention restores the shape of a moving body from a photographed image under relatively strong ambient light and displays the same or demodulates an invisible image embedded in a moving image from the moving image and displays the same. An image processing method according to the present invention is provided with: (a) a step S1 for emitting flashing light onto the surface of an object on the basis of a spread-spectrum modulated signal, (b) a step S2 for receiving light reflected from the surface of the object and outputting a signal including image information, (c) a filtering step S3 for removing noise including a low frequency component from the signal including the image information, (d) steps S4, S5 for despreading and demodulating the filtered signal, and (e) a step S6 for outputting an image reflecting the state of the surface of the object on the basis of the demodulated signal.
