Abstract: An ergonomic “press-on-press-off” capture mode is added to an existing “press-and-hold” capture mode in a portable hand-held scanning device without adding additional control buttons or requiring the user to make a selection between which capture mode to use. Supporting both capture modes simultaneously is accomplished through monitoring the capture button and distance traveled by the device. When the capture button is pressed and released, a check is made to see if the device was moved a predetermined distance while the capture button was depressed. If yes, then the press-and-hold capture mode is confirmed, and image data capture ends. If no, then the press-on-press-off capture mode is confirmed, and image data capture continues, even though the capture button is not depressed, until a second press of the capture button or lift off. The second press of the capture button or lift off terminates the image data capture for the press-on-press-off capture mode.

The send page module controlling the transfer of data to another device includes code segments for establishing a communication link over a first communication port with the target device, monitoring the status of the link while the transfer is in progress, and displaying an animation on the display screen that graphically portrays the transfer of image data to the target device.

Abstract: Moire patterns are significantly suppressed in a scanner that continuously varies its number of lines per inch. The number of dots per inch in the direction different from the relative motion between the scanner and the document is generally a fixed property of the optical sensor, but in the LPI direction the distance between consecutive lines can be made to randomly vary between a maximum distance and a minimum distance. This spatially distributes the moire effect, and prevents its accumulation into the usual recognizable two dimensional pattern.

Abstract: An appliance indicates that it is transferring information over a wireless communication path to an external device by displaying an animation. In one embodiment, an animation indicates that the appliance is attempting to establish communication over an infra red (IR) port with the external device by displaying an animation having an light emitting diode (LED) with emanating waves propagating away from the LED. Movement of the waves stop when communication is established. The wave edges indicate a maximum cone angle indicating the direction that the IR port must be pointed to establish and maintain communication with the external device.

Abstract: An appliance provides for the selection of data to be transmitted to an external device by selecting metaphoric page icons, each icon corresponding to a page of captured information. Metaphoric page icons may be selected by selecting the icons individually, by selecting a predefined group of icons, by selecting tagged icons, or by selecting all icons. A default selection includes selecting the current metaphoric page icon displayed on the display.

Abstract: A hand-held image capture and communication appliance and method of using same are provided wherein images may be captured and saved in an internal memory. The appliance includes a processor for manipulating and exhibiting the images on a built-in display screen. Program code stored in the internal memory and executed by the processor includes a delete page module for purging the memory of captured images when they are no longer needed. The delete page module includes a code segment for displaying an animation, which, in the preferred embodiment, is designed to convey the concept to the user that a delete operation is irreversible. One implementation of the animation shows the deleted page or group of pages turn into ashes, which is a metaphor for the permanence of the delete operation. A confirmation prompt is provided prior to carrying out the delete operation to inform the user how many pages or images will be deleted and what percentage of memory will be freed.

Abstract: A document scanner generates an 8-bit binary word for each picture element (PEL) of a document. One of a group of 256 different binary words is thereby generated in accordance with the image/background content of each document PEL. These scan words vary in magnitude from hexadecimal "00" to "FF", representing a PEL containing only white background, or representing a PEL containing only the most dense black portion of the document's image, respectively. An intensity and/or contrast look-up table memory element, or a computation means, each having 256 addressable locations or inputs, is addressed using the scan words. Each storage location or input is addressed by one of the 256 possible document PEL words. The stored content of each storage location in the look-up table memory element, or the value that is computed by the computation means, comprises an enhanced 8-bit binary word that varies as a function of user selected image intensity and/or contrast enhancement.
