摘要： In an image reproducing method capable of displaying annotations in virtual space constituted by a group of real panoramic images, if an object for which an annotation is to be displayed falls within the field of view at the position of the observer, the object is adopted as the display position of the annotation. If the object is not within the field of view, then the direction of forward travel of the observer is adopted as the annotation display position. If the object is in a state of transition, then the annotation display position is decided by interpolation.

摘要： The engine misfire detection apparatus of the invention successively determines whether a rotational fluctuation difference Nxd360 as a difference between a rotational fluctuation Nxd at a certain crank angle CA of an engine and a rotational fluctuation Nxd at a 360 degree-prior crank angle CA exceeds a predetermined reference value A1 (step S150) and whether a rotational fluctuation difference Nxd720 as a difference between the rotational fluctuation Nxd at the certain crank angle CA and a rotational fluctuation Nxd at a 720 degree-prior crank angle CA exceeds a predetermined reference value B1 (step S160). The engine misfire detection apparatus detects a misfire of the engine upon satisfaction of all conditions regarding rotational fluctuation difference proportions Nja2, Nja3, and Nja4 on the basis of the rotational fluctuation difference Nxd360 (step S200) and all conditions regarding rotational fluctuation difference proportions Njb2, Njb3, and Njb4 on the basis of the rotational fluctuation difference Nxd720 (step S210), when both the rotational fluctuation differences Nxd360 and Nxd720 exceed the respective reference values A1 and B1 (steps S150 and S160). This arrangement ensures adequate and accurate detection of an engine misfire during warm-up of a catalyst included in an exhaust emission control unit with a significant delay of the ignition timing in the engine.

摘要： An image/map association division displays map data stored in a map data storing division, and sets a plurality of segment points and a “path” (route) sandwiched by two segment points on a map. The image/map association division reproduces video data stored in an image data storing division, and displays the map data stored in the map data storing division. If the route set on the map and desired frames of the video data being reproduced are designated via an operation division, association data for associating the segment points at both ends of the “route” with the designated frames is generated and it is stored in the association data storing division.

摘要： There is provided an image processing apparatus for describing a real image as a virtual object using space data formed based on a photo image of the real object, and generating a virtual image of the virtual object using the space data. The image processing apparatus captures the photo image of the real object from a real camera viewpoint position while illuminating the real object by an illumination light source placed at a real illumination position. The captured photo image is converted into space data in the form of an object for each pixel, and the space data is stored in a memory together with various illumination conditions at the real illumination position to allow a search at a later time.

摘要： Upon observation of multi-viewpoint images, even when the viewpoint moves continuously, the image cannot normally be displayed in correspondence with the continuous movement of the viewpoint, and an image from a viewpoint closest to the current viewpoint is displayed. To prevent this, each two adjacent images of the multi-viewpoint images are interpolated by detecting corresponding pixels and generating an interpolated image in accordance with the correspondences among pixels. The interpolated image is generated in such a manner that an epipolar plane image is generated by juxtaposing corresponding lines of the multi-viewpoint image, straight lines are detected from the epipolar plane image, and the intersecting points between interpolated lines and the detected straight lines are detected as interpolated pixels. In this case, as for a point for which a straight line cannot be detected, a straight line passing the point is estimated, thereby generating an interpolated pixel. When a plurality of straight lines are detected for a pixel of interest, the priority level is assigned to the pixel of interest in correspondence with the number of detected straight lines. When the priority level is smaller than that of another pixel through which the detected straight line passes, the straight line is ignored, and an interpolated pixel is not generated.

摘要： An image processing method according to an embodiment of the present invention has the following steps: the multi-viewpoint image input step for inputting images obtained from a plurality of viewpoint positions arranged on different straight lines, the detection step (2, 7, 17, 8) for detecting a viewpoint position and its view direction in which a user is seeing at the viewpoint position, and the image generation step (11, 12, 13, 8) for generating a virtual image viewed from the predetermined viewpoint by using the images input in the multi-viewpoint image input step on the basis of the detected predetermined viewpoint position and the view direction. In the image generation step, optimal corresponding points are obtained by detecting a straight line having a width on an epipolar plane image corresponding to the input images, thereby generating an image.
