Abstract:
When determining whether or not an image of an original input from an image reading device is a copy-prohibition image, a mounting position, a mounting angle or the like of the original is detected, and it is determined whether or not exact determination can be performed. If an exact determination cannot be performed, a signal instructing to again read an image of the original is output, and the operator is provided with a warning.
Abstract:
To provide a device capable of determining uniquely the direction of rotation applied to an image and extracting digital watermark information correctly even in the case where a registration signal having a symmetric axis is embedded. A device for enabling digital watermark information to be extracted from image data having the digital watermark information embedded therein in such a manner that it can hardly be perceived by human eyes, in which processing for extracting rotation information and position information from the image data is performed plural times for rotation angles different from one another. For extracted position and rotation information, confidence coefficients indicating accuracy thereof are calculated. The position and rotation angle at which the digital watermark information is embedded are determined based on the confidence coefficients.
Abstract:
To provide adaptive image processing for a portrait, face information about the face of a person contained in an image is acquired, and it is determined on the basis of the face information whether a significant personal face is contained in the image. If there is face information representing the presence of a significant personal face, adaptive processing adjustment information which adjusts the contents of high quality processing for a portrait, which should be executed for the process target image, is generated from the face information about the face of the person contained in the image. The high quality processing adjusted on the basis of the adaptive processing adjustment information is executed for the image.

Abstract:
This invention allows a user to simultaneously control geometric parameters for a camera and suppresses a deterioration in the image quality of distributed video images while keeping the cost low. The invention includes an image sensing area calculation unit for calculating a minimum image sensing area including required areas from clients, a required video image forming unit for forming required video images by extracting video images of the respective required areas from a video image of the image sensing area which is sensed, and a video image transmission I/F for distributing the formed required video images to the respective clients. Only the minimum area including the respective required areas is sensed, and video images of the respective required areas are cut from the video image and distributed to the respective users, thereby allowing a plurality of users to simultaneously control the camera and obtain video images at desired viewpoints and view angles. In addition, since only one camera is used, the required cost can be kept low, and the electronic zoom magnifications of video images to be distributed can be suppressed low, thereby minimizing a deterioration in the image quality of each required video image.

A varying command to vary the attitude of a video camera selected from one or more video cameras and a variation speed at which to vary the attitude of the video camera are inputted, the attitude of the video camera is varied on the basis of the inputted varying command and variation speed, the electronic shutter speed of the video camera whose attitude is being varied is calculated on the basis of the inputted variation speed of the attitude of the video camera, and the electronic shutter speed of the video camera whose attitude is being varied is controlled on the basis of the calculated electronic shutter speed of the video camera.
Abstract:
An edge vector extraction unit (122) extracts edge vectors from an input image, and a variable-magnification processing unit (123) performs smoothing/variable-magnification processing of the edge vectors. A vertex point adjustment unit (100) selects each of vertex points constituting an edge vector loop as a vertex point of interest, discriminates the directions of two vertex vectors, which sandwich the edge point of interest, and adjusts the coordinate position of the vertex point of interest sandwiched between the two edge vectors having a predetermined combination on the basis of the combination of the directions, thereby suppressing a deformation of an output image, which may be caused by the variable-magnification processing.
Abstract:
The present invention relates to a polishing method using a grindstone comprising abrasive grains and a bonding resin for bonding the abrasive grains, as well as to a polishing apparatus to be used for the polishing method. By using a resin for bonding abrasive grains, it is possible to obtain a grindstone having a desired modulus of elasticity. With such a grindstone, the surface of a substrate having concave and convex portions can be rendered uniformly flat, irrespective of the size of the concave and convex portions. Further, by first polishing the substrate surface with a polishing tool of a small elastic modulus and thereafter polishing it with a polishing tool of a large elastic modulus, it is possible to obtain a polished surface of reduced damage. The method of the invention is effective in planarizing various substrate surfaces having concave and convex portions.
Abstract:
An associative memory device having a high speed and good performance is provided without degrading the simple design of a peripheral circuit of a conventional associative memory. The associative memory device has an N-bit first buffer and an M-bit second buffer in which W-bit data is stored through a data input port, detection device for detecting that the W-bit data is input to the first buffer k times or to the second buffer r times, a switch for alternately switching buffers in which the W-bit data is stored, and a search control for performing a search operation for a memory region by using data in the first or second buffer. By using data in the first or second buffer, during the search operation for the memory region of the associative memory, the W-bit data for the next search operation is input to the second or first buffer.
Abstract:
The contour vectors of an image are stored in a small storage capacity, and are enlarged/reduced in correspondence with a desired variable-magnification factor to be faithful to an input image. For this purpose, when a binary image is input from a binary image input unit (11), a contour vector extraction unit extracts contour vectors, and detects the positions of isolated points. The contour vectors are enlarged/reduced by a vector variable-magnification/smoothing unit (13), and a binary image is reproduced by a binary image reproduction unit (15). On the other hand, each of the isolated points is subjected to variable-magnification processing by an isolated point variable-magnification processing unit (14), so that its position is converted into a position corresponding to the variable-magnification factor, and points corresponding in number to the variable-magnification factor form the isolated point. Thus, the storage capacity of the isolated points can be reduced, and the isolated points are subjected to variable-magnification processing at an appropriate variable-magnification factor corresponding to the desired variable-magnification factor.
