Patent number: 7587094Abstract: 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.Type: GrantFiled: June 10, 2005Date of Patent: September 8, 2009Assignee: Konica Minolta Sensing, Inc.Inventors: Koji Fujiwara, Takanobu Ojima

Patent number: 7423666Abstract: 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.Type: GrantFiled: May 20, 2002Date of Patent: September 9, 2008Assignee: Minolta Co., Ltd.Inventors: Kuniteru Sakakibara, Eiro Fujii, Koji Fujiwara

Patent number: 7196683Abstract: 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.Type: GrantFiled: April 10, 2001Date of Patent: March 27, 2007Assignee: Sharp Kabushiki KaishaInventors: Tomohiko Yamamoto, Hisashi Nagata, Youji Yoshimura, Noboru Noguchi, Hideki Ichioka, Koji Fujiwara, Naoto Inoue, Keiichi Tanaka

Patent number: 7176441Abstract: 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.Type: GrantFiled: October 31, 2003Date of Patent: February 13, 2007Assignee: Konica Minolta Holdings, Inc.Inventors: Hironori Sumitomo, Koji Fujiwara
