Patent number: 7573462Abstract: An image display apparatus which is capable of operating smoothly over a plurality of image display devices. When a pen has come into continuous contact with a first display screen, a system controller determines whether or not the pen has got out of contact with an edge of the first display screen. When the system controller determines that the pen has got out of contact with the first display screen at the edge thereof, a time period elapsed is measured while the pen is held out of contact with the first display screen at the edge thereof. When the measured time period is less than a predetermined time period, the system controller outputs pointing information indicative of a position of the edge of the first display screen with which the pen got out of contact, to indicate that the pen has been held in the continuous contact with the first display screen.Type: GrantFiled: June 3, 2005Date of Patent: August 11, 2009Assignee: Canon Kabushiki KaishaInventor: Akihiro Ouchi

Patent number: 7242370Abstract: In a multidisplay system, an image is displayed without necessitating a display control signal supplied from an external device. Each image display device in the multidisplay system includes an interface for receiving image data and transferring the image data to an image display device at a downstream location. Each image display device also includes a DDC (Display Data Channel) communication processor and a rewritable memory for storing EDID (Extended Display Identification Data) information. When another image display device is connected at a downstream location, EDID information is acquired from the connected image display device via the DDC communication processor, and display resolution information and interconnection information are set. In particular, the display resolution described in the EDID information is rewritten by the display resolution information set in the above process.Type: GrantFiled: September 9, 2003Date of Patent: July 10, 2007Assignee: Canon Kabushiki KaishaInventors: Akihiro Ouchi, Shigehiro Kadota

Patent number: 6753829Abstract: To change image quality in accordance with the image to be displayed, a color filter plate 3 is driven to sequentially split the white light incident on an A portion into red, blue, and green light beams to irradiate a liquid crystal panel, thus displaying a full-color image by a so-called field sequential scheme. In this case, if a sector region 4BG of an auxiliary filter plate 4 is always matched to the A portion (FIG. 2A), the quality of a full-color image is defined by the color filter plate 3, resulting in an increase in luminance. In contrast to this, when a red filter section 3R and auxiliary red filter section 4R are synchronously driven to be simultaneously irradiated with white light, the quality of a full-color image is defined by both the color filter plate 3 and the auxiliary red filter section 4R. As a consequence, an image with excellent color reproducibility is obtained.Type: GrantFiled: July 3, 2001Date of Patent: June 22, 2004Assignee: Canon Kabushiki KaishaInventor: Akihiro Ouchi
