Patent number: 6747619Abstract: In the method of quantitatively evaluating the front of screen quality of a screen to be checked, an image of the screen to be checked is captured. The image of the LCD panel is captured preferably in a state in which the screen to be checked of the LCD panel is on. The captured image is processed and evaluated preferably in accordance with a predetermined algorithm. In the present invention, a manual evaluation is not performed at all. Thus, the front of screen quality of the screen to be checked of the LCD panel or the like, for example, can be quantitatively evaluated.Type: GrantFiled: January 12, 2000Date of Patent: June 8, 2004Assignee: International Business Machines CorporationInventors: Kosei Tanahashi, Yumi Mori

Patent number: 6710770Abstract: A system used with a virtual device inputs or transfers information to a companion device, and includes two optical systems OS1, OS2. In a structured-light embodiment, OS1 emits a fan beam plane of optical energy parallel to and above the virtual device. When a user-object penetrates the beam plane of interest, OS2 registers the event. Triangulation methods can locate the virtual contact, and transfer user-intended information to the companion system. In a non-structured active light embodiment, OS1 is preferably a digital camera whose field of view defines the plane of interest, which is illuminated by an active source of optical energy. Preferably the active source, OS1, and OS2 operate synchronously to reduce effects of ambient light. A non-structured passive light embodiment is similar except the source of optical energy is ambient light. A subtraction technique preferably enhances the signal/noise ratio. The companion device may in fact house the present invention.Type: GrantFiled: September 7, 2001Date of Patent: March 23, 2004Assignee: Canesta, Inc.Inventors: Carlo Tomasi, Abbas Rafii

Patent number: 6677925Abstract: In an active-matrix LCD device, a coupling signal in accordance with a sum of outputs of data signal lines is detected by a detection-use bus line crossing each of the data signal lines. The coupling signal is superimposed via a coupling capacitor on an input signal that serves as a reference, and is inverted and amplified by a inverting-amplifying section, then it is outputted as a common electrode signal. With this, a waveform that corresponds to a sum of the outputs is coupled with the common electrode signal. As a result, the common electrode signal is caused to have an influence that corresponds to a fluctuation of a potential of the common electrode due to outputs of the data signal lines and that is reverse in phase, thereby enabling to prevent horizontal shadow due to the outputs of the data signal lines. Thus, it is possible to realize an active-matrix-type LCD device in which horizontal shadow can be prevented with low power consumption.Type: GrantFiled: September 6, 2000Date of Patent: January 13, 2004Assignee: Sharp Kabushiki KaishaInventors: Takafumi Kawaguchi, Toshihiro Yanagi

Patent number: 6636205Abstract: A line parameter detection circuit (70) of this invention includes an active video detector (72) that generates an “active video” signal (102) indicative of a video signal (100) containing video data that exceeds a predetermined threshold level. The line parameter detection circuit further includes three counters (82, 84, 86) that are incremented by a reference clock (110). The counters are reset and start counting reference clock pulses upon receiving an HSYNC pulse (104). A left edge register (90) stores the count accumulated in the first counter upon receiving a rising edge of the active video signal, a right edge register (92) stores the count accumulated in the second counter upon receiving a falling edge of the active video signal, and a line length register (96) stores the count accumulated in the third counter upon receiving the next subsequent HSYNC pulse. Each video signal scan line includes blanking periods (106, 108) between the HSYNC pulses and the active video region.Type: GrantFiled: April 10, 2000Date of Patent: October 21, 2003Assignee: InFocus CorporationInventor: Alan L.
