摘要： An initial polygon obtained from a point group is used as a control polygon, and a control point of the control polygon is offset in a normal direction by the shortest distance from a limit surface generated by the control polygon, so that the position of new control point is determined to allow a subdivision surface to interpolate the initial polygon, thereby generating the subdivision surface which interpolates the point group. A first process to determine the point on the subdivision surface at the shortest distance from each control point, and a second process to move and offset the control point in the normal direction from the surface by the distance between the point on the surface and the initial control point, are iterated until the distance between the initial point group and the point on the surface satisfies the threshold or becomes smaller than the threshold, thereby generating the subdivision surface interpolating the initial polygon. Consequently, the subdivision surface interpolating the point group is generated within a short operation time period, without solving a linear system.

摘要： An image processing apparatus and an image processing method are provided. The image processing method is implemented by the apparatus, which receives and stores captured image data. Addresses for the captured image data are generated and stored in a look up table in memory along with color signal data that is stored in an additional data area. Output image data is generated by interpolating the address information in the lookup table to determine coordinate information for the output image. The output image coordinate information allows for drawing an output image with corrected image distortion, corrected perspective distortion, altered viewpoint from captured image, mirror-image conversion, or electronic zooming of the captured image. Color signal data from the additional data area is then used to draw an overlay on the output image in color.

摘要： An image processing method includes storing corresponding addresses of original image data in respective addresses of a look-up table, the number of the respective addresses being smaller than the number of addresses that are necessary in output image data; determining whether the addresses of the original image data corresponding to the addresses of the output image data exist in the look-up table; calculating the addresses of the original image data in a first interpolation process if the addresses do not exist in the look-up table; and generating the output image data corresponding to the addresses of the output image data in a second interpolation process based on the original image data by using at least one of the calculated addresses of the original image data and the addresses of the original image data in the look-up table.

摘要： A printing apparatus includes a printing head for printing on a bank book, a platen disposed opposite the printing head, and a cam mechanism for moving the platen. A sensor detects the thickness of the bank book which is between the printing head and the platen, and a sensor moving mechanism moves the sensor toward or away from the platen. A controller controls the operation of the cam mechanism and the sensor moving mechanism as the sensor is moved to a measuring position approaching the printing head. The printing head is moved toward the platen according to a detected value and then the sensor is retracted from the measuring position. As a result, after moving the printing head, the sensor does not contact the surface of the bank book, and therefore does not produce jamming or oblique feeding of the bank book during a line feed or printing operation.

摘要： A shape evaluation device performs simulation by using an annular light source or concentric light source instead of a rectilinear light source and calculates a characteristic line for performing shape evaluation. The shape evaluation device includes a calculation device (2) having: a distance vector calculation unit (2a) for acquiring a distance vector representing a distance between the circle and the vector, a distance function unit (2b) for acquiring a distance function from the distance vector, and a distance function calculation unit (2c) for acquiring a point on a curved surface where the value of the distance function is a predetermined value. By performing simulation using the annular or concentric light source, it is possible to obtain a characteristic line capable of observing distortion in all the directions by one calculation. The present invention reduces the number of calculations required for calculating the characteristic line for performing shape evaluation and reduce the time required for calculation, thereby enabling evaluation by a dynamic shape.
