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. An 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: A method and circuit for excluding regions from an exposure calculation is described. The method includes obtaining pre-image data representing an image of a scene and dividing the image into a plurality of regions. Regions that contain a predetermined number of bright pixels are identified, bright pixels being pixels that are brighter than a threshold level of brightness. Each region that has at least the predetermined number of bright pixels from the exposure calculation are excluded.

Abstract: A method and apparatus for capturing a plurality of overlapping images using an imaging device are described. The method includes receiving input indicating a start of a multi-image capture, input indicating an end of a multi-image capture, and storing a current image. Each time an amount of rotation of the imaging device about at least one axis exceeds a displacement angle, a new current image is stored until the input indicating the end of the multi-image capture is received.

Abstract: A digital imaging device is operated to capture a first image in a digital format. At least two non-contiguous portions of the first image are rendered in a display of the digital imaging device. The at least two non-contiguous portions of the first image are used to align a live version of a second image in the display, wherein the second image is an extension of the first image. The second image is captured in a digital format. A corner matching algorithm is applied to determine an offset of the second image with respect to the first image, wherein the offset is required to achieve a substantially accurate alignment of the first and second images. Application of the corner matching algorithm is limited to an overlap region intervening between the at least two non-contiguous portions of the first image.

Abstract: A system and method for effectively utilizing a live preview mode in an electronic device includes a capture subsystem configured to generate image data that has luminosity characteristics that vary depending upon corresponding exposure settings of the electronic device. A display controller of the electronic device analyzes the image data from the capture subsystem to create a live preview representation of the foregoing exposure characteristics of the image data. In certain embodiments, the live preview representation may include a live preview histogram. The display controller then displays the live preview representation on a display of the electronic device in either a manual live preview mode or an automatic live preview mode. The display controller may be utilized to adjust the exposure settings of the capture subsystem after the live preview representation is analyzed to efficiently optimize the luminosity characteristics of the image data.

Abstract: A method and apparatus for obtaining and maintaining accurate time. A preferred apparatus includes a dedicated timekeeping device, a time synchronization client, and an access point. The timekeeping device is adapted for counting local time. The time synchronization client is adapted to transmit a query signal for querying a time server over a network to cause the time server to provide a current server time. The access point is adapted for producing a wireless signal representative of the current server time for wireless transmission to the timekeeping device, for synchronizing the local time of the dedicated timekeeping device to the current server time.

Abstract: A central processing unit (310) in a display system carries pixel-value signals and software-address signals representing the locations of the pixels whose values the pixel-value signals represent. An address-translation circuit (420) converts those software addresses to logical addresses representing the locations of those pixels in a 90°-rotated version of the image that the software address signals represent, and the logical addresses are applied to an image-buffer memory (410) to specify the locations in which to store the pixel values. A refresh-address circuit (620) generates the address signals used in fetching from the image-buffer memory (410) the values that are applied to a display device (360) employed to display the image. The refresh-address generator (620) is operable alternatively in row-forward and row-reverse modes and alternatively in column-forward and column-reverse modes.

Abstract: A computer system includes an operator input device, a central processing unit (CPU), and a display device, such as a liquid crystal display (LCD) or cathode ray tube (CRT) providing a visible image to the computer user as an output of computer activity. The computer system includes a video display controller (VDC) with a graphics generator. This VDC receives image information, such as text or graphics generated by the CPU, or retrieved by the CPU from another facility (such as a CD-ROM) of the computer system, and responsively provides image signals driving the CRT or LCD display. The VDC includes a power saving controller implementing one of several available power saving modes dependent upon one or more of several possible inputs. Each of the power saving modes includes the same list of VDC functions which may individually be enabled or disabled in each power saving mode dependent upon a bit value entered into a register of the power saving controller.
