Patent number: 7343320Abstract: A system is provided that allows a photographer to take images for a customer and provide those images to order servicing equipment with which the images are placed on-line for the customer to view. The customer may place orders for the images and products and services related to the images. The order servicing equipment may credit the photographer when the customer orders images, products, or services. Images may be manipulated before images, products, or services are ordered. Images may be taken using film-based cameras or digital image acquisition equipment. Image presentation options may be selected. Content may be appended to the images. Web sites and digital albums may be created using the images. The photographer may check the status of assignments that have been submitted to the order servicing equipment and may check on account status. Different rights levels may be established for different parties. Loyalty rewards may be awarded for frequent use of the system.Type: GrantFiled: August 2, 1999Date of Patent: March 11, 2008Inventors: G. Victor Treyz, Susan M. Treyz

Patent number: 7327493Abstract: An object of this invention is to provide an image reading apparatus which can reselect a film type after prescanning, and after confirming the result on the monitor, perform actual scanning. To achieve this object, a film scanner selects from a color table storage a color table corresponding to the type of film, sets the color table in an image data converter, and performs prescanning. If the user reselects a film type after prescanning, the color table set before prescanning and a color table selected after prescanning are transferred to a confirmation image changing unit where the difference between the two tables is calculated. Prescanned image data is transferred from a memory to the confirmation image changing unit, added to the difference, and returned to the memory. The color table selected after prescanning is set in the image data converter, and scanning for obtaining a high-resolution image is executed.Type: GrantFiled: April 7, 2003Date of Patent: February 5, 2008Assignee: Canon Kabushiki KaishaInventors: Shigeki Yamada, Takahisa Akaishi

Patent number: 7317560Abstract: In an image reading apparatus that can read a reflection original and transparent original, a film holder for holding the transparent original is provided to be pivotal to the left or right about a shaft as the center. After the transparent original is set such that its image can be seen correctly, when the film holder is brought down to the right, the film can be set correctly concerning its upper and lower sides. At this time, as the film holder is held by the reading apparatus, its positional shift can also be prevented.Type: GrantFiled: January 11, 2005Date of Patent: January 8, 2008Assignee: Canon Kabushiki KaishaInventors: Takayuki Nishinohara, Yasushi Ishida, Shigeyuki Sugiyama, Katsumi Obana, Hiroyuki Noguchi

Publication number: 20070291329Abstract: A thin transparent media adapter is used when scanning transparent media on a contact image sensor or reduction optics scanner. The adapter uses illumination from an existing scanner light source to illuminate a diffuser and the media. A lens assembly is used to focus the light from the media to create an intermediate image between the adapter and the scanner platen glass. The adapter is an optical assembly that forms an intermediate image of the transparent media in the image side focal plane of existing scanner optics. The existing scanner optics can then capture and focus the light from the intermediate image onto the scanner's existing sensor array. The adapter magnetically couples to the scan system to allow the lens array to follow movement of the optical system of the scanner.Type: ApplicationFiled: June 14, 2006Publication date: December 20, 2007Inventor: Kurt Eugene Spears

Installation for increasing a scanning range of a scanner along an axial direction of a light source
Patent number: RE40678Abstract: An installation for increasing the scanning range along the axial direction of the light source. The installation includes a light source and a transparent glass panel. The light source provides a light beam necessary for scanning a document. The transparent glass panel has a coating thereon for lowering light transparency near the mid-portion of the light axis relative to either end.Type: GrantFiled: September 2, 2005Date of Patent: March 24, 2009Assignee: Transpacific IP, Ltd.Inventor: Jen-Shou Tseng
