Patent number: 7003172Abstract: The technique of the present invention carries out specific image processing that emphasizes articulation of display with a varying degree of emphasis for respective sites of an image projected by a projector. A typical example of such image processing is sharpness adjustment. The degree of emphasis in sharpness adjustment at each site is specified, based on an elevation angle of the projector and a focalized position of the projected image. The technique of the invention thus readily prevents deterioration of the image quality due to out-of-focus state of the projected image.Type: GrantFiled: July 9, 2002Date of Patent: February 21, 2006Assignee: Seiko Epson CorporationInventors: Kesatoshi Takeuchi, Kazuyoshi Nakamura

Publication number: 20050094110Abstract: A projector 10 of the invention measures the brightness of an image projected on a screen SC and corrects the measured brightness of the projected image with an input zoom ratio of a projection lens and an input projection distance. The projector 10 compares the corrected brightness of the projected image with a preset target value and sets a driving power of a light source lamp 52 to compensate for a difference between the normalized brightness and the preset target value. This arrangement effectively restrains potential adverse effects of a variation in luminance of illumination light emitted by the light source lamp of the projector on the brightness and the contrast of a resulting projected image.Type: ApplicationFiled: September 20, 2004Publication date: May 5, 2005Applicant: SEIKO EPSON CORPORATIONInventor: Kazuyoshi Nakamura

Publication number: 20010004270Abstract: An imaging device has both ends fixed to a metallic belt installed on two pulleys. A controller reversely turns a stepping motor to restore the imaging device to a position of origin and then a height sensor calculates the number of pulses according to imaging distance sensed. The controller rotates the motor in a forward direction to linearly transport the imaging device in a direction beginning at the origin position to stop the imaging device at a focused point. An autofocus operation can be achieved under feedforward control. This leads to a high-speed control operation, and the positioning can be conducted with high precision. The autofocus operation can be achieved at a high speed with high precision.Type: ApplicationFiled: December 21, 2000Publication date: June 21, 2001Applicant: NEC CorporationInventors: Kazuyoshi Nakamura, Kenichi Matsumura

Patent number: 5758039Abstract: Upon issuance of a check, predetermined mark data are added to data and letters indicating an amount of money so as to be converted into new data and letters indicating the amount of money. Further, the printing capacity of a preset printing area on the check is compared with the volume of printing data to be printed, and a printing font to be used is selected in accordance with a result of the comparison. A separate template on which a plurality of initial printing positions and codes for indicating the initial printing positions are indicated is superposed with the check, and the corresponding code is inputted so as to designate an initial printing position. With this arrangement, it is possible to provide a small-sized printer which can enhance the visibility of the content printed on the check, can prevent the letters indicating an amount of money on the check from being raised so as to enhance the trust in banking transaction, and can easily set an optimum printing position.Type: GrantFiled: March 20, 1997Date of Patent: May 26, 1998Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Kazunori Shibata, Kiyoshi Baba, Tsutomu Egashira, Kenichi Ohsato, Masahiro Kondoh, Yuji Tanaka, Kazuyoshi Nakamura, Hiroyuki Fukusako
