摘要： In order to generate three-dimensional form data having characteristic lines desired by a user from original three-dimensional form data, a closed surface consisting of longitudes and meridians is arranged so as to inscribe a three-dimensional form model, and the longitudes and the meridians are projected to a surface of the three-dimensional form to generate parametric curves running along the surface. Then, control points of the parametric curves are moved to adjust the curves so that a part of the parametric curves in correspondence to the movement of the control point moves along the surface of the form model. The curves adjusted are taken as three-dimensional form data of the form model.

摘要： In a processor for generating a three-dimensional form model, data MX on an object having a three-dimensional form are read, while two-dimensional color image GX1 are read in correspondence to the form data MX. Then, color boundaries are discriminated in the color image GX1, and the form data MX are thinned except portions in correspondence to the color boundaries. Thus, the amount of data is reduced without losing information on the color boundaries of the form.

摘要： When a scanning start position set signal is input in an area image sensor, the content is transferred to a vertical scanning circuit, and the scan start position is set. Image of a desired row is read by horizontal scanning. Then, one shift signal for vertical scanning is input, the position of scanning is shifted by one row, and horizontal scanning is performed. Thus image of the next row is read. By repeating this operation, a desired strip-shaped image is read. The shape of the object is determined and when a portion is determined to have complicated shape, the image data is input by means of a lens having long focal length, and image data of other portions are input by means of a lens having short focal length. By putting together a plurality of input image data, image data as a whole is generated.

摘要： An optical device includes: a light source that emits a light beam; a deflector that deflects the light beam in a main-scanning direction; and a scanning/image-forming optical system that includes a scanning lens that causes the light beam deflected by the deflector to converge to a scanned surface to form an image on the scanned surface. The scanning lens has refractive index gradient. At least one surface of the scanning lens is a tilt-decentered surface that has a tilt angle, which depends on a position in the main-scanning direction, in a sub-scanning direction. The tilt angle is set so as to compensate for variation, which results from the refractive index gradient, in direction of the light beam in the sub-scanning direction.
