Abstract: A system and method for authenticating a user of an image processing system. User credentials are received at an authentication device corresponding to an image processing device, and transmitted to a first server remote from the authentication device. The validity of the user credentials are judged by comparing the received user credentials to authentication information stored at the first server, and a result of the judging is transmitted to the image processing device. The image processing device then requests access to a second server remote from the image processing device, and the second server transmits a request for the user credentials to the first server. After receiving the user credentials from the first server, the second server performs user authentication.

Abstract: A reliable charge pump circuit includes an operational amplifier; an upper current mirror; a lower current mirror; a startup circuit; and an anti-lock circuit, wherein the anti-lock circuit includes a current source and a diode-connected NMOS transistor, which increases the driving strength of the operational amplifier to two NMOS transistors connected to an output node of the operational amplifier, so as to prevent deadlock caused by multiple stable status and improve production yield.

Abstract: A method of invoking a set of services corresponding to a plug-in application installed on an image handling device. The method including launching a host application of the image handling device, accessing a configuration file of the image handling device, the configuration file including an identification of at least one plug-in and a corresponding set of services, launching the identified at least one plug-in, the plug-in providing the corresponding set of service in an integral fashion to the host application and presenting a unified graphical interface including host application services and the corresponding set of service of the plug-in.

Abstract: An image processing device and method for modifying images on an image processing device including a scanner configured to produce an image of at least one document having multiple pages, a communications interface configured to connect the image processing device to a server via a network, a display unit configured to display a preview image or a thumbnail image of at least one of the pages of the scanned document and a user interface configured to display a selectable graphical indicia corresponding to at least one operation for modifying the preview image or the at least one image of the scanned document.
