摘要:
Techniques are disclosed for coupling a printer to a communications network (such as the a Plain Old Telephone Service network), downloading printing information (such as a digital image) to the printer over the communications network, and using the printer to print output based on the printing information. A user may use the printer to connect to a printing server that serves the printing information. Prior to transmission of the printing information to the printer, the printing server may process the printing information to tailor the printing information based on the capabilities of the printer. The printing server may communicate with the printer using one or more printing protocols. The printer may be equipped with a controller for communicating according to the printing protocol. Downloads of printing information to the printer may be interrupted and subsequently resumed from the point of interruption.

An adaptive halftoning method where the difference between a digital image and a filtered digital image is introduced into the system on a pixel by pixel basis is disclosed. In this method, each input difference pixel has a corresponding error value of the previous pixel added to the input value at a summing node, resulting in modified image difference data; the modified image difference data is passed to a threshold comparator where the modified image difference data is compared to a threshold value, the threshold value varying according to the properties of the digital image, to determine the appropriate output level; the output level is subtracted from the modified image difference value to produce the input to an error filter; the output of the error filter is multiplied by an adaptation coefficient, where the adaptation coefficient varies according to the properties of the digital image, to generate the error level for the subsequent input pixel; and, the cyclical processing of pixels is continued until the end of the input data is reached.

System and methods are disclosed that provide users of mobile digital devices the opportunity to obtain a permanent record of the service rendered at the mobile device for all modes of web based services, location based services, services originating at the mobile device and not related to the location of the device, services originating via a voice portal, web based services originating via voice communication. Services include location independent services, such as tickets and coupons, and location based services, such as obtaining directions/or and maps to the nearest store or hotel or to a given location, obtaining traffic information, and receiving location-based coupons at the mobile device.

Imaging system whereby color image data intended for reproduction on an image reproduction means may be provided to a functional engine for modification according to one or more functional transforms. Color management may be applied to the data before output to the selected image reproduction device, so as to achieve WYSIWYG color matching of the image data with respect to the color fidelity limitations or other characteristics of the intended image reproduction device.

Systems and methods are disclosed that provide users of mobile handheld digital devices the opportunity to share large data objects, such as images or digital audio files, with multiple users and the opportunity to upload a data object from a data object source and transmit the uploaded data object to a remote server in order to make the uploaded data object available for sharing with multiple users. The shared data objects can be accessible via a link to the object or by means of reduced size versions of the shared data objects.

Techniques are disclosed for uploading content (such as a digital photograph) from a content upload device to a content server over a communications network, and for automatically forwarding the content from the content server to one or more remote destinations. A user of the content upload device may cause the content upload device to upload the content to the content server by initiating a single action, such as pressing a single button on the content upload device, and without providing information identifying the user to the content upload device. Upon receiving the content, the content server may add the content to a queue, referred to as a content outbox, associated with the user. The content server may automatically forward the content in the user's content outbox to one or more remote destinations specified by preferences associated with the user's content outbox.

Techniques are disclosed for coupling a printer to a mobile communications device (such as a cellular telephone), downloading printing information (such as a digital image) to the printer over a wireless network through the mobile communications device, and using the printer to print output based on the printing information. A user may use the mobile communications device to connect to a printing server that serves the printing information. Prior to transmission of the printing information to the printer, the printing server may process the printing information to tailor the printing information based on the capabilities of the printer. The printing server may communicate with the printer using one or more printing protocols. The printer may be equipped with a controller for communicating according to the printing protocol.
