Publication number: 20010005220Abstract: In an image pickup device, a crystal as an optical low pass filter is rotatable in a vertical plane that is vertical to an optical axis. In a normal mode and a shift mode, the crystal is rotated in order to change a separation direction of pixels. Thereby, moirés in a circular zone can be eliminated in the normal mode, and moirés in a high frequency side can be eliminated in the shift mode while a contrast zero line is not passed through the center section of the circular zone in order to prevent the decreasing of a resolution and to improve the characteristic of the shift mode. Because the rotary mechanism can be formed simply and smaller, the device can be manufactured with a low coast and a high realibility.Type: ApplicationFiled: December 19, 2000Publication date: June 28, 2001Inventors: Yoshichi Otake, Fumio Nidaira, Hideki Tengeiji, Shouji Sakamoto

Publication number: 20010005221Abstract: A current frame portion (21) stores therein the most recent information of an image of those fingerprint images input from an inputted unit (1), while a previous frame portion (22) stores therein image information saved in the current frame portion (21). A pixel comparing portion (31) compares mutually corresponding pixel gray-level value information saved in the current frame portion (21) and the previous frame portion (22) respectively.

Publication number: 20010005260Abstract: An ophthalmologic apparatus is disclosed, in which even in the case where the range of lateral relative movement of a trestle is limited with respect to a base, the measurement can be continued without enlarging the space occupied by the apparatus body and without imposing an extra burden on the testee. The apparatus composes a trestle (4) mounted on a base (3) and laterally movable relative to the base (3) and has a limited range, and a measuring head portion (5) mounted on the trestle (4) and automatically laterally moved relative to the trestle (4) with respect to a reference position (H1). In the case where the trestle (4) moves rightward or leftward and reaches a movement limit position O2, O3, the reference position (H1) of the measuring head portion (5) with respect to the trestle (4) is shifted in the direction in which the trestle (4) moves.Type: ApplicationFiled: December 21, 2000Publication date: June 28, 2001Inventors: Kunihiko Hara, Yasuhisa Ishikura, Hiroshi Iijima

Publication number: 20010005261Abstract: An autostereo projection system uses multiple projectors to form an essentially seamless and extended field of view. Each projector is registered to a CRT display. Shutter elements in each projector create multiple pupils for each CRT display. Each CRT display is driven with different images for each shutter pupil. Seamlessness is promoted by the use of a tunable optical diffuser as part of a common lenticular viewing lens.Type: ApplicationFiled: February 27, 2001Publication date: June 28, 2001Applicant: Litton Systems, Inc.Inventors: Graham Martin, Joseph L.

Publication number: 20010005262Abstract: An image projection method and an image projector are adapted to shut down the laser beams instantaneously when an obstacle intruding into the projection area of the laser beams is detected. A detection wave is projected onto a display screen 3 along with laser beams for displaying an image and detect the reflection wave of the detection wave reflected from the display screen 3 to find out the obstacle, if any, intruding into the projection area of the laser beams. The laser beams are shut down when the intrusion of the obstacle is detected.Type: ApplicationFiled: December 28, 2000Publication date: June 28, 2001Applicant: Sony CorporationInventor: Katsuaki Tsurushima

Publication number: 20010005264Abstract: An inspection system for identifying defects on the surface of an item includes an information processor mounted on a base assembly. A tray is used to move the item to an inspection station on the base assembly, and an illuminator is provided at the inspection station to illuminate the item from different visual perspectives. Importantly, the illuminator includes a plurality of different light sources. An N number of cameras and an M number of image processors are operated in concert to collect image data from the illuminated item. This image data is then analyzed using the image processors to compare the image data with a template image to detect defects in the item. In the operation of the inspection system, the tray, the illuminator, the cameras and the image processors are all centrally controlled and coordinated by an central information processor.Type: ApplicationFiled: February 16, 2001Publication date: June 28, 2001Inventors: Charles S. Slemon, W. James Frandsen, Raymond H. Bratton, James John Glover

Publication number: 20010005265Abstract: A jet of water in a cylindrical form is supplied from a jet nozzle onto a measurement surface of a substrate to form a column of the water extending between the nozzle and the measurement surface Light is emitted from an irradiation fiber and transmitted through the column of water to the measurement surface. The light reflected by the measurement surface is received by a light-receiving fiber through the column of water. A measurement calculation unit measures the thickness of a film formed on the substrate, based on the intensity of the reflected light.Type: ApplicationFiled: December 13, 2000Publication date: June 28, 2001Inventors: Toshifumi Kimba, Shunsuke Nakai

Publication number: 20010005267Abstract: A facsimile machine adapted to receive data from a remote device (data transmitter) over LAN and transfer the data to a recipient over LAN or PSTN. A memory of the facsimile machine stores delivery conditions such as e-mail address of registered recipients and delivery day and time. A controller determines whether a request for data transfer from the data transmitter should be accepted, based on an address of the data transmitter and the registered e-mail addresses if the data transfer request is attached to the received data. If no data transfer request is attached, the controller determines whether the data should be transferred depending upon a current time and the registered day and time. In the latter case, the data transmitter does not have to append the data transfer request and recipient information to the data. Instead, the controller finds out an appropriate recipient in the delivery condition table.Type: ApplicationFiled: December 8, 2000Publication date: June 28, 2001Applicant: MURATA KIKAI KABUSHIKI KAISHAInventor: Yoshifumi Tanimoto

Publication number: 20010005268Abstract: A facsimile server connected to a mail server and a client over a network, and capable of sending and receiving an e-mail via the mail server. Certain data in a header of an e-mail to be sent to a recipient is used as identification data indicative of an origin of the e-mail. A controller identifies the origin of the e-mail based on the identification data upon receiving reception acknowledgement from the recipient. The facsimile server sends the reception acknowledgement to the client if it determines that the e-mail origin is the client. On the other hand, the facsimile server causes a printer to print the reception acknowledgement if it determines that the e-mail is originated from the facsimile server itself.Type: ApplicationFiled: December 18, 2000Publication date: June 28, 2001Applicant: Murata Kikai Kabushiki KaishaInventor: Masashi Eguchi

Publication number: 20010005269Abstract: A system which enhances the process of specifying the settings of paper input and paper output by a printer driver. The system causes a Properties dialog box to be displayed on a display. The dialog box includes an image, which is an icon schematically illustrating the appearance of a printer, a paper input settings display box showing information relating to paper input to the printer, and a paper output settings display box showing information relating to paper output from the printer to be displayed in a mutually correlating manner with indication lines. Namely, the system does not require the user to switch over the card when the user carries out both the settings of paper input and the settings of paper output. The paper input settings display box has radio buttons corresponding paper output sources. The user clicks one of the radio buttons to select a desired input paper source. The paper output settings display box has checkboxes corresponding to paper outputs.Type: ApplicationFiled: December 12, 2000Publication date: June 28, 2001Applicant: Seiko Epson CorporationInventor: Shinji Nozawa
