An apparatus for processing images of a display includes an image sequence receiving module adapted to receive a first sequence of images of the display. The first sequence of images includes at least one image corrupted due to partial refreshing of the display. The apparatus also includes an image processing module operable to process the first sequence of images on an image by image basis to eliminate the at least one corrupted image from at least one of the first sequence of images and a second sequence of images captured subsequent to the first sequence of images.

In a method for obtaining a resource to read a symbol, an image containing at least one of the symbol and an indicator of the symbol is obtained. At least a portion of the obtained image is sent to a symbol identification service and the resource from the symbol identification service is received, wherein the resource enables the symbol to be read.

Obtaining a resource to read a symbol

A system for determining layout of print data printed by a printer onto a recording medium, in which the recording medium is processed by a target device different from the printer. Printing capabilities of the printer and processing capabilities of the target device are both determined. Then, layout of the print data is determined based on compatible capabilities between the printing capabilities of the printer and the processing capabilities of the target device. The layout preferably is determined through communication with the printer and the target device so as to negotiate the layout.

A user interface for image acquisition devices that provides common control of common features of different image acquisition devices while retaining the flexibility needed to provide tailored control that take advantage of unique features of each different image acquisition device. The user interface includes a control area for displaying a property sheet. The property sheet has a plurality of property pages, each of which has an interface for image acquisition device control and each of which has a tab describing the control provided by that property page. At least one property page has an interface for core image acquisition device control, and at least one property page has an interface for device-dependent image acquisition device control. The user interface also provides a property sheet with a property page that attractively provides plural interfaces for control in that property page. The property page includes a control region for providing control and a button region having multiple buttons. An appearance of the control region is changed in response to user manipulation of the multiple buttons, with each different appearance providing a different interface for the control.

Color management system having interchangeable gamut mapping methods

In a method for fabricating a nanowire thermoelectric device, a first electrode pattern is formed on a substrate, wherein the first electrode pattern includes bottom electrodes and a first set of connections which connects the bottom electrodes to form first and second groups of electrically connected bottom electrodes. P-type nanowires and n-type nanowires are selectively formed on the substrate by selectively activating either the first group of electrically connected bottom electrodes and the second group. The p-type and n-type nanowires are then connected by top electrodes. A first set of holes in the substrate is formed to remove the first set of connections. A second set of holes to allow for electrical access to the bottom electrodes, and a second set of connections are formed, so as to result in an array of thermocouples connected to each other in parallel banks of series-connected thermocouples.

Dynamic gamut mapping selection

An application programming interface (API) that provides a common interface between an application program and plural different types of color measuring devices each having at least one color measuring sensor. The API includes plural functions for operating any of the plural different types of color measuring devices. In order to complete an operation performed by at least one of the plural functions, the function that performs the operation must be called a number of times which is different for at least two different types of color measuring devices. For a particular color measuring device, the API provides the application program with flow control data of the number of times that the function must be called. This flow control data preferably can be provided by the function, in the form of a call-again value or as a numerical value, or by a separate function in the API such as a get-device-capabilities function. In some embodiments of the invention, a combination of these methods of providing the flow control data is utilized. Preferred functions for operating any of the plural different types of color measuring devices include a calibrate-position function, a calibrate-sensor function, a move-to-patch function, and a make-measurement function.

Managing color data to transform CMYK source color data from a source device into CMYK destination color data for rendering by a destination device, the CMYK source color data and the CMYK destination color data being comprised of color pixels represented by cyan (C), magenta (M), yellow (Y) and black (K) values, in which a source color profile and a destination color profile are accessed, the source color profile containing a source color transform and the destination color profile containing a destination color transform. A determination is made, for each pixel of the CMYK source color data, whether the pixel has a non-zero C, M or Y value. In a case that a pixel is determined to not have a non-zero C, M or Y value, the CMYK source color data corresponding to the pixel is set into the CMYK destination color data, and in a case that a pixel is determined to have a non-zero C, M or Y value, the CMYK source color data corresponding to the pixel is transformed from a source device color space into CMYK destination color data in a destination device color space. In the transforming step, the source color transform is applied to the CMYK source color data corresponding to the pixel to generate device-independent color data in a device-independent color space, and the destination color transform is applied to the device-independent color data to generate the CMYK destination color data.

Color management of black data

Transformation of CMYK source color data from a source device into CMYK destination color data for rendering by a destination device, in a case which the &ldquo;K&rdquo; channel of the CMYK source color data was generated by a source black generation algorithm. A source color profile corresponding to the source device and a destination color profile corresponding to the destination device are accessed. The source color profile contains a first transform and a copy of or reference to the source black generation algorithm; the destination color profile contains a second transform. An inverse of the source black generation algorithm is applied to the CMYK source color data to generate CMY source color data, the first transform is applied to the CMY source color data to generate device-independent color data, the second transform is applied to the device-independent color data to generate CMY destination color data, and the source black generation algorithm is applied to the CMY destination color data to generate the CMYK destination color data.

Black generation for color management system

A system for mapping an input point to a surface of a color gamut in a color space. A two-dimensional slice of the color space is selected. The two-dimensional slice includes the input point. A projection point in the two-dimensional slice and a projection between the input point and the projection point are determined. An intersection point between the projection and a mathematical approximation in the two-dimensional slice also is determined between points at least substantially on the surface of the color gamut. A new mathematical approximation is determined between points at least substantially on the surface of the color gamut, based on the intersection point. The intersection point is redetermined at an intersection between the projection and the new mathematical approximation. The determination of the new mathematical approximation and the redetermination of the intersection are repeated until the intersection point satisfies a goodness criteria.
