摘要： PROBLEM TO BE SOLVED: To provide an image processor which can easily set each color that can be identified or the opacity, etc., when plural display objects are represented in the same three-dimensional space. SOLUTION: This image processor which composes the 1st and 2nd images and displays them is provided with a 1st image input part which inputs the 1st image having the 1st intensity distribution, a 2nd image input part which inputs the 2nd image having the 2nd intensity distribution, an intensity distribution conversion part which converts the 2nd intensity distribution into a 3rd intensity distribution that does no overlap the 1st intensity distribution, a feature value mapping part which maps the feature value in the 2nd area set on the 2nd image, a composing processing part which composes the 1st and 2nd images to make a 1st area overlap a 2nd area according to the intensity distribution of the 2nd area where the feature value in the 3rd intensity distribution is mapped and generates a synthetic image and a display part which displays the synthetic image.

摘要： PROBLEM TO BE SOLVED: To effectively present sensation information, which is close to natural human sensation employing a simple constitution, by changing the relationship between the amount of direction movement and the photographing direction of an actual picture image within a prescribed condition. SOLUTION: A magnetic coil sensor 10 and a magnetic coil sensor 11 of the person to be presented measure the azimuth of the body trunk of the person and the data relative to the azimuth of the person's head and the respective azimuths are computed by a signal processing section 13. Then, from the computed respective azimuths, a picture azimuth computing section 14 computes the azimuth of the presented picture by a function and a photographing direction changing means 17 directs an actual picture photographing means 16 to the computed picture azimuth under the control of an actual picture direction control section 15. For example, in front of the trunk, the actual picture in the direction of the head is presented. In the left and the right sides, the actual pictures in the outer directions are presented. Thus, in an actual photographing space or in a virtual space, visual information is obtained employing the same sensation in the actual space in a certain range and wide range visual information is obtained by a small head motion.

摘要： PROBLEM TO BE SOLVED: To obtain an image processor which can facilitate manual operation and reduce the work load, and extract an object fast with adequate precision. SOLUTION: This invented image processor generates a result image 117 which has an object extracted nearly automatically from a slice image by a ROI segmentation part 106, a threshold process part 108, a connection/ disconnection part 110, an area narrowing-down part 112, and a shape feature quantity calculation part 114. Then, a wrong extracted area decision part 118 decides whether or not a wrong object is extracted as to plural result images 117 and fills a result image 117 having a wrong object extracted with a correct object by interpolating the result images before and after the image to facilitate manual operation, so that the object can be extracted fast with adequate precision.
