Abstract: A display controller is provided. The display controller is configured to provide an indirect addressing mode to access a memory location within the display controller. The display controller includes a first pin configured to enable access to one of a register of the display controller or a memory region of the display controller based upon a logical level of a first signal received by the first pin. A second pin is included. The second pin is configured to define the access to the register or the memory region as one of address information or data based upon a logical level of a second signal received by the second pin. The display controller includes an extra pin mode module configured to enable the first signal to select the data to access memory without accessing a register block. A device and methods for implementing an indirect addressing mode is also provided.

Abstract: The invention is directed to a method and apparatus for reducing the bandwidth required to transmit image data to a display device. It is contemplated that the image data represents a plurality of pixels defining an image for display on the display device, and that the image data is transmitted in a data stream with the data being in a predetermined order of pixel components. The method comprises the steps of receiving the image data from the data stream, and transforming the image data as it is received by selectively storing some of the image data in a memory for access by the display device and discarding other of the image data.

Abstract: A system for translating a portrait-oriented software address to a portrait-oriented yet landscape-configured display address. Based on the orientation of a display device, an address translation system either passes the software address “as is” or translates the address to represent a portrait-oriented display address. A refresh address generator operates alternatively in column-forward and column-reverse modes, and additionally operates alternatively in row forward and row reverse modes to selectively rotate the image.

Abstract: The invention is a hardware switching apparatus for initiating a soft power-down and a remote power-up in a computer system. The apparatus includes a power supply, a switching device having a first switch position and a second switch position, a switching circuit, and a wiring harness for remotely controlling the switching circuit. The power supply senses the power delivered from a primary source and produces a power-down signal when the power is interrupted. When the switching device is in the first switch position, the switching circuit is adapted to cause the power supply to produce a power-down signal. When the switching device is in the second switch position, the switching circuit is adapted to cause the power supply to produce a start-up signal.

Abstract: A system and method for performing an interface save/restore procedure in an electronic device includes a processor that begins to execute a first task in conjunction with a host interface of a display processor. The processor subsequently receives an interrupt request for executing a second task that has a higher priority than the first task. A save/restore module responsively stores task states from the host interface into an interface states register. The task states correspond to an interrupted execution point in the first task. The processor temporarily stops the first task to execute the second task. The save/restore module restores the stored task states to the host interface after the second task is completed, and the processor may then efficiently resume the first task.

Abstract: A label printer can continue to print labels without causing a paper jam even when the label detector is not operating. During label printing by the label printer 1, this method confirms if the label detection operation of the optical sensor 14 disposed near the label dispensing slot 3 is normal or not (step ST2). If normal, the next label printing operation starts automatically after a label is printed and the optical sensor 14 detects that the label has been removed from the label dispensing slot 3 (steps ST3, 4, 5). If not normal, an error indicating LED flashes to inform the operator and operation switches to a manual label printing mode in which the optical sensor 14 is not used and starting the next label printing operation waits for manual input (steps ST6, 7, 8). Labels can still be printed when the optical sensor 14 is not operating normally.

Abstract: A data pipeline and clock control (relationship) that allows image data from a camera to pass directly through a display controller to an LCD without being written into, temporarily stored, and read out of a display buffer, e.g. a VRAM, is provided. Elimination of the video memory (VRAM) lowers the chip cost, reduces the power requirements, reduces delay due to writing and reading from the video memory, and reduces the pin count since fewer power pins are required.

Abstract: In a case where application data stored in a PC database 300a are edited by a PC 300, and the edited contents are to be reflected to contents of the memory of a terminal database 200a, PC 300 refers to a synchronization profile SP including item IDs and ID numbers of a most recent synchronization communication and communication time information of the synchronization communication, thereby detecting which items have been edited at a time subsequent to completion of a most recent synchronization communication.

Abstract: A system and method of editing a digital image to remove an unwanted object includes designating a rectangular region of the digital image including a subset of pixels within the digital image that includes the object to be removed. A band of pixels adjacent one major side of the rectangular region is selected and a mirror of the selected band of pixels is copied in a repeating pattern to define a first matrix corresponding in size to the designated region. A band of pixels adjacent the opposite major side of the rectangular region is then selected and a mirror of the selected band of pixels is copied in a repeating pattern to define a second pixel matrix corresponding in size to the designated region. The pixels of the first and second matrices are blended according to a first blending equation to create an initial texture.

Abstract: The invention is directed to a method and apparatus for mapping defects on a light transmissive support surface of a document scanning or photocopying device. The method includes a step of cleaning the support surface between steps of operating the device so as to reflect light from defects associated with the support surface. At least a selected characteristic of the reflected light, such as its intensity, at predetermined pixel locations before the step of cleaning is compared with the same characteristic of the reflected light at the same pixel locations after the step of cleaning. A selected pixel location is mapped to a defect map if (1) the characteristic for reflected light is substantially equal for the selected pixel location at each step of operating the device, and (2) the characteristic for the reflected light at a step of operating the device substantially meets a predetermined standard.

The selecting circuit has inputs coupled to the respective storage outputs of the memory pair and an output coupled to a control line of the switch for controlling the switch. A selecting line of the selecting circuit selects between the inputs, for selecting one or the other of the storage outputs of the first and second storage elements.

Abstract: A method of producing an adaptive partial ink layer for a pen based computing device is described. The adaptive partial ink layer is used to form an ink trail, which follows the input pen as it moves in contact with a touch screen. This allows the user to view the input while it is being made, which allows the input to be improved through the visual observation. A three-cell block is formed to permit single character input from the pen and then the block is extended in the direction of a cursive input to accommodate a word or phrase. Whereas, a common direction for the cursive input is from left to right, any direction emanating from the three cell block can be used if the interpreter of the pen passed computing device is set up to allow such an input.

Abstract: An apparatus and a method for processing checks and other negotiable instruments efficiently captures MICR data required for electronic payment and an image of the check or negotiable instrument enabling the amount, payee, and other information printed or written on the check face to be clearly read. The image reading unit 11 of the check processing apparatus 110 scans and outputs a gray scale image of the check. A threshold value determination unit 12 sets a threshold value for digitizing the image data based on the density level frequency distribution of primary gray scale image data obtained by the image data reading unit scanning a first scanning area T. This first scanning area contains part of a printed text area 127 where text is printed on the negotiable instrument and part of the background 49 of the negotiable instrument.
