Abstract: A mechanical assembly for fine focus of a wafer-level camera module includes a threaded lens acceptor for mounting with a wafer-level compatible image sensor and a complimentary threaded lens base for mounting with a wafer-level lens stack. In a method of forming a wafer-level camera with a mechanical fine focus assembly, the lens base and the lens acceptor rotationally couple to join the lens stack with the sensor, and to adjust z-height of the camera module to achieve optimal focus. The camera module is secured at the optimal focus position.

Abstract: An apparatus for recapturing electrical charge from a capacitor is provided. The apparatus includes a charge recovery controller configured to generate a signal indicating when the electrical charge from the capacitor is to be recovered. The apparatus also contains a charge recovery circuit configured to transfer the electrical charge from the capacitor to a battery upon receipt of the signal.

Abstract: A sheet misfeed detection system comprises an audio sensor configured to detect an audio signal generated by a sheet fed by an automatic document feeder (ADF) and a detection module configured to detect a misfeed condition of the sheet based on the audio signal generated by the sheet.

Abstract: An imaging system comprises a calibration system adapted to perform a calibration scan of a charged luminescent calibration strip disposed in a scan window of an automatic document feeder. The calibration system is adapted to determine whether an opaque object is disposed within a visible area defined by the scan window from the calibration scan.

Abstract: A memory management system and method includes, in one embodiment, an index location in a hash table that represents metadata, and a file memory address saved at the index location so that the hash table is searchable by a processor by entering the metadata into a hash function to transform the metadata into the index location where the memory address is stored.

Abstract: An imaging device power management system comprises a control circuit adapted to adapted to vary a duty cycle of a scanning module of an imaging device during a scanning operation performed by the scanning module based on a source of energy coupled to the imaging device for operating the scanning module.

Abstract: A duplex detection imaging system comprises a scanning device having a photosensitive element disposed therein for receiving light reflected from a front surface of a document. The photosensitive element is also adapted to receive light reflected from a back surface of the document while the front surface of the document is oriented toward the photosensitive element for determining whether an image resides on the back surface of the document.

Abstract: A “see-through” scanner comprises a touch-sensitive panel that enables a scanner user to designate an area to be scanned by touching the scanner.

Abstract: A digital camera and related methods enable a scrolling slideshow of captured images across a display screen. The display screen can be the digital camera's display screen or an external display screen (e.g., a TV screen or a computer monitor) driven by the digital camera. The number of images scrolled across a display screen can be adjusted for ease and efficiency of viewing based on user preference. The camera provides controls for image scrolling including speed adjustment, forward scrolling, reverse scrolling, scroll pausing, and scroll resuming. The camera permits images to be locked in place on the display screen during the scrolling slideshow, which provides for easy comparison with other images that continue to scroll across the display screen. When an image is locked, scrolling images appear to scroll to a position behind the locked image.

Abstract: A digital camera is built having a still mode and a video mode. The camera is configured to control two different light sources. When the camera is in still mode, it is configured to fire a strobe during capture of the image. When the camera is in video mode, it is configured to turn on a continuous light source during capture of the video. These two different light sources may be combined into a single unit or may exist as separate devices. In video mode, a partial depress of the shutter control may turn on the continuous light source prior to exposure, allowing the light source to stabilize before video capture begins.

Abstract: Disclosed are systems and methods for image scanner feature detection comprising an image scanner feature treated to facilitate detection of an associated feature artifact in a scanned image, wherein the treated image scanner provides a predetermined optical diversity attribute.

Abstract: A media recording device comprises a receiver operable to receive a broadcast signal comprising a media transmission, a storage device operable to continuously store the received media transmission, a user input device operable to receive an input from a user indicative of a date and time occurring in the past for playback of the stored media transmission, and a playback device operable to play back stored media transmission beginning at the user-provided date and time.

Abstract: A file-saving system is disclosed for saving an active file as multiple new files.

Abstract: A digital camera and method that provide the ability to dynamically partition memory (both internal and removable) into memory dedicated for saved images and memory dedicated for deleted images. Deleted images may occupy as much memory as is available down to a user or factory selectable minimum. When a user deletes an image it is moved from a saved memory partion into a deleted memory partition, and when the memory partition dedicated to deleted images is full, then images are automatically and permanently deleted. In a preferred embodiment, the deleted images are automatically and permanently deleted on a first-in first-deleted basis. The deleted memory partition may be a physical memory partition or may correspond to indexed memory locations of the deleted images.

Abstract: A digital camera having an improved user interface for use in viewing and editing still images and viewing and editing video, along with a method of displaying, editing and scrolling through video recorded by the digital camera. The user interface includes a display device for selectively displaying recorded images, a slide bar, and left and right slidable buttons that are moveable in left and right directions across the slide bar and that are operative to display and scroll through recorded still frames of the video corresponding to the location of the respective slidable button. The left and right slidable buttons are depressible to activate respective switches, wherein the left slidable button is depressible to select the first frame of video and crop preceding frames, and wherein the right slidable button is depressible to select the last frame of video and crop succeeding frames.

Abstract: A digital camera and automatic mode detection method that eliminates the need for a user to select between video recording mode and still image mode while using the camera. The appropriate mode is automatically selected by the digital camera based upon the length of time its shutter button is depressed.

Abstract: A scanner that illuminates a partial width of a scan line is disclosed. The scanner first determines the needed scan width and then performs a scan where the full width of the scan is not illuminated.

Abstract: Application data is stored in a redundant array of independent memories. In one embodiment, the application data is entered in a first memory. The first memory is parked when the first memory has received the application data. The second memory is unparked and application data is entered in the second memory. The second memory is also parked when the second memory has received the application data, thereby reducing the likelihood of losing application data due to physical impacts to the memories.

Abstract: A system and method is described for installing a new memory into a redundant array of independent memories. The method comprises initiating a duplication function in a processor, transmitting an empty data indication from the new memory to the processor, and replicating application data from a first old memory to the new memory. An embodiment of the system comprises a processor, a bus in communication with the processor, a first memory in communication with the processor in a first data path removed from the bus, and a second memory in communication with the processor in a second data path removed from the bus and having an empty memory indicator so that, in response to the second memory containing no application data, it provides a corresponding indication to the processor.
