発明の名称 (英語) IMAGE PROCESSING METHOD
発明の概要(英語) 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.
従来技術、競合技術の概要(英語) BACKGROUND ART
Conventionally, a light source such as a projector using a digital camera, image processing for restoring the shape of the object from the photographed image is a method/system has been proposed. For example, Patent Document 1 is, the grid pattern is projected onto the object observed on the imaged image including the image processing for restoring the shape of an object from a disclosed method. Patent Document 2 is, an object that moves to the imaged image including the projection pattern demodulated from the phase of the synchronization pattern, the image processing method for restoring the shape of the object is disclosed. Patent Document 3 is, under the ambient light projected to the object on the imaged image including a grid pattern with a band pass filter for restoring the shape of the object from the image processing method is disclosed.
In addition, the non-patent document 1, based on the Hadamard matrix to the object by using the plurality of light sources are activated at the same time, the shape of an object from the images captured by the camera to restore the image processing method is disclosed. Further, the non-patent document 2, spread spectrum modulation using the information embedded in the image (display) to restore the demodulation of the disclosed method.
