  • Patent number: 7587094
    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.

  • Patent number: 7423666
    Abstract: The present invention provides a three-dimensional chart, a parameter acquiring method and an information processing device that are used for carrying out camera calibration in a wide range with high precision. For this reason, a plurality of unit graphic forms the sizes of which are coded by using different cross-ratios are placed on side faces of a three-dimensional chart. The cross-ratios of unit graphic forms are calculated from a picked-up image of the three-dimensional chart, and by collating these with actual values, the position and orientation of the image-pickup point are determined. The shifting average of the heights of the unit graphic forms is made approximately proportional to the distance from the apex so that it is possible to reduce the limitation of image-pickup distances. A movable camera is attached to a subject-use camera, and upon picking up an image of the subject, an image of the three-dimensional chart is also picked up simultaneously.

  • Patent number: 7205984
    Abstract: A pen input unit includes ultrasonic receivers that receive an ultrasonic signal transmitted from an ultrasonic transmitter of an input pen. Based on the received signal, the distance (distance value) of the ultrasonic transmitter from each of the ultrasonic receivers is determined. The distance value is used for the display control of the display panel, and is supplied to a reception sensitivity control section. The reception sensitivity control section carries out reception sensitivity control for reducing a difference in level of the respective waveforms received by the ultrasonic receivers. As a result, a pen input display device of an ultrasonic pen input system is provided that prevents errors over the entire input area of the display panel without increasing power consumption or impairing operability of pen entry.

  • Patent number: 7196683
    Abstract: In an image display device which employs pulse width modulation driving, a voltage which is less than a voltage supplied to signal lines is applied to pixel electrodes. Tones are displayed by shifting phases of waveforms of the signal lines and scanning lines, and polarities of pixels in a signal line direction are inverted alternately. This prevents increase in power consumption which is caused by pulse intervals which become too small at high tone levels, in addition to preventing change in tone level due to external factors such as temperature, or signal delays in a driver or wiring.

  • Patent number: 7176441
    Abstract: A counting system is for counting the number of persons passing a monitor line set in the width direction of a path, and has a laser for irradiating the monitor line with a slit ray, and an image capturing apparatus for photographing an area including the monitor line. In the image capturing apparatus, one-dimensional data indicative of a position in which the slit ray is interrupted on the monitor line is generated from an image obtained by the photographing. On the basis of the one-dimensional data, the number of passing persons is counted. By counting the number of passing persons with the one-dimensional data, a very light computation load for the counting can be achieved.
