Abstract: A biological information processing apparatus is strong against the noises or disturbances, and can accurately determine an evaluation value or blood vessel age. A pulse wave acquirer acquires pulse wave information of a living body and a frequency analyzer analyzes a pulse wave frequency based on the pulse wave information obtained by the pulse wave acquirer. The characteristic value extractor extracts a characteristic value from pulse wave frequency information obtained by the analysis carried out by the frequency analyzer and a pulse wave property calculator calculates a pulse wave property or blood vessel age based on the characteristic value extracted by the characteristic value extractor.

Abstract: Input position is accurately detected. In an x-detection period of a non-display period, a source drive circuit simultaneously applies to all signal wiring lines a pulse of a peak value proportional to a distance from a gate drive circuit. A coordinate detection circuit obtains an x-coordinate on the basis of a voltage induced at a pen corresponding to the peak value (x-coordinate) of the applied pulse. In a y-detection period, a pulse generation circuit applies one pulse to a common line. The pen detects a potential variation in amplitude proportional to a distance (y-coordinate) from the source drive circuit, generated approximately simultaneously on all the signal wiring lines via a capacitance. The coordinate detection circuit obtains the y-coordinate similarly to the case of x-coordinate detection.

Abstract: A reference image of a pattern having a first pitch and projected on a sample 1 by a projector 6 is captured by a camera 5. Next, a measuring image of a pattern having a second pitch and projected on the sample 1 by the projector 6 is captured by the camera 5. Here, the second pitch of the pattern light is determined by a value calculated based on the phase resolution of the pattern light having the first pitch. Then, using the reference image thus obtained, phase coupling for the measuring image is performed. The three-dimensional shape of the sample is obtained in this manner.

Abstract: In order to provide a curved surface model generating technique which makes use of both advantages of a modeling method by using distance image data and a modeling method by using silhouette data while photographic and measurement data from less angles are utilized, firstly a curved surface model generating section inputs 2D color image data and distance image data. When silhouette image data are extracted from the 2D color image data, initial model data are generated by the Volume Intersection method or the like. The distance image data are converted into world coordinate values by using photographing position/posture data. In a fitting processing section, a fidelity where the distance with the distance image data is used as a measure and a fidelity where the distance with the silhouette image data is used as a measure are added to be evaluated, and a curved surface is fitted to initial model data so that curve surface model data are generated.

This method comprises the steps of: (a) in each of discrete coordinate positions within a coordinate system for rendering a volume, obtaining a value corresponding to the distance to the boundary of a viewed volume defined by the contour of the image of said object and by the point of view of said image; and (b) in each of said coordinate positions, on the basis of a plurality of said values obtained for said images of said object, determining a value corresponding to the distance to the object surface and then maintaining said value in a manner corresponded to said coordinate position. In the method, multi-valued data can be assigned to each vertex or lattice point, and therefore, a small number of voxels can represent precisely the three-dimensional shape.

A region lying between the reference point and the outermost point of measurement is defined as a no-data region, and an additional point is produced in the no-data region. Thus, the device can easily complement the range image data, thereby to easily produce the 3-D shape data based on the range image data.
