Abstract: The shape of a moving object is reconstructed from a shot image under relatively-strong ambient light or an embedded image is demodulated from a video image in which an image that may not be visually recognized is embedded to display the image. The image processing method of the present invention includes irradiating flashing light to the surface of the object based on a spreading signal obtained by spread spectrum modulation, receiving reflected light from the surface of the object to output the signal including the image information, a filtering for eliminating noise including a low-frequency component from the signal including the image information, inverse-spreading the signal after the filtering to demodulate the signal, and outputting, based on a signal obtained by the demodulation, an image reflecting the state of the surface of the object.

Abstract: Provided are an image processing device, an image processing method, and a program which are capable of high density restoration and which are also strong to image processing. An image processing device mainly consists of a projector serving as a projection means, a camera as a photographing means, and an image processing means consisting of, for example, a personal computer. The image processing means acquires the intersection point between patterns from a photographed image and calculates a first solution including degree of freedom by using the constraint condition of a first tentative plane and a second tentative plane including the intersection point and the constraint condition obtained from the positional relationship between the projector and the camera. The degree of freedom is cancelled by primary search, thereby restoring a three-dimensional shape.
