Abstract: An object of the present invention is to provide a device that is capable of presenting image information that is larger than an object by irradiating light onto the object that moves on a trajectory that is not known. An object tracking section controls line of sight direction so as to be directed towards a moving object. A rendering section irradiates a light beam in a direction along the line of sight direction. In this way the rendering section can irradiate the light beam onto the surface of the object. It is possible to present information, that has been rendered in a range that is larger than the surface area of the object, to an observer, utilizing an after image of the light beam that has been irradiated on the surface of the object.

Abstract: The present invention relates to technology for detecting three-dimensional motion of an object in a non-contact manner, at high speed, and with comparatively high precision. A speed detection section 11 detects speed of an object using a first laser beam 111 that is irradiated towards an object 100, and is reflected by the object 100. A distance detection section 12 detects speed of the object 100 using a second laser beam 121 that is irradiated towards the object 100, and is reflected by the object 100. The second laser beam 121 is configured to be irradiated at substantially the same time and to substantially the same position as the first laser beam 111. A motion calculation section 13 calculates motion of the object 100 using information on orientation of the first and second laser beams, the speed, and the distance.

Abstract: This invention provides a technology that allows the acquisition of background differentials using images acquired by a camera, the viewpoint of which moves. First, said camera acquires a background image, i.e. an image that does not contain a target object. Using information on the line-of-sight direction and viewpoint position of the camera, position information for pixels in the background image is transformed to polar-coordinate information Next, the camera acquires an object image. Using information on the line-of-sight direction and viewpoint position of the camera, position information for pixels in the object image is transformed to polar-coordinate information. The polar-coordinate information for the pixels in the object image is used to identify a target background, said target background being the part of the background image in an angle region corresponding to the object image. By comparing the object image and the target background, the differential therebetween is extracted.

Abstract: A blurless image capturing system sequentially acquires images with little blur, even in a situation where a camera moves. An image capturing camera unit and a mirror unit are both capable of continuous movement in at least a one-dimensional direction. The image capturing camera unit acquires an image of a physical object present within an object region by directing line of sight direction towards the object region by means of the mirror unit. The mirror body changes the line of sight from the image capturing camera unit. The drive unit changes an angle of the mirror body in a given angular velocity in accordance with movement of the image capturing camera unit and the mirror body In this way it is possible to keep the line of sight from the image capturing camera unit directed towards a physical object for a given time. The drive unit directs the line of sight from the image capturing camera unit towards another object region by driving the mirror body. The control unit controls operation of the drive unit.
