A method and apparatus for organizing digital images that contain a persons face is disclosed. A database of known faces allows the faces in the images to be identified. The names of the people identified in the image are used in naming the image files and in naming the path to the image files.
摘要:
An improved progress monitor or progress dialog box for a computer system that uncovers or reveals information as the progress bar indicates progress in addition to changing the colors or shades of the progress bar. The information displayed can be the text of a story, the punch line of a joke, or any other information that can inform or entertain the user.
摘要:
Described is a method which corrects for malfunctioning or inoperable ink ejection elements in a one-pass printmode. The method comprises obtaining the standard printmask; identifying the ink ejection elements which are malfunctioning; ascertaining ink ejection elements adjacent to the ejection elements which are malfunctioning; selecting particular adjacent ink ejection elements from the adjacent ink ejection elements; and modifying the standard printmask by adjusting the amount of ink deposited by the selected adjacent ink ejection elements to create a modified printmask.
摘要:
A method of expanding the on-track operational range of a disk drive based upon detection of an external vibration condition. The method involves detecting that a vibration state exists and, while the existence of the vibration state is detected, modifying the default on-track-declaration algorithm such that a data transfer operation can be completed in less time than if the default on-track-declaration algorithm was in use.
摘要:
Systems for providing information to a user are provided. In this regard, a representative system includes an identification device. The identification device incorporates a locator and a transmitter. The locator is configured to facilitate determining a location of the identification device so that information corresponding to a user of the identification device and information associated with the location of the identification device can be transmitted via the transmitter to a services system. In response to the information provided by the identification device, the services system can provide information to the user via the first identification device based, at least in part, on the location of the identification device. Image-capturing devices also are provided.
摘要:
A completely passive adapter for scanning transparent images in a reflective scanner. Mirrors are used to capture light from a lamp that is internal to the scanner and to reflect that light thought a transparent image along the light path required by internal scanner optics. For larger images, a lens is added to capture additional light. Different embodiments of the adapter accommodate variation in angles of optical paths and offset between the light source path and the light detection path. Embodiments are provided having two tilted mirrors, two mirrors plus an optical wedge, four mirrors, and seven mirrors. An optional graduated density optical filter may be added to compensate for nonuniform illumination.
摘要:
A method for determining when overall lamp intensity is stable for a lamp in a document scanner. The intensity of a relatively small portion of the lamp is controlled as part of a closed loop intensity control system. During a warm-up transient period, the intensity of the small portion of the lamp is monitored and power to the lamp is monitored. A changing power to the lamp indicates that the overall lamp intensity has not stabilized. Scanning is initiated when the intensity of the monitored portion of the lamp is within a predetermined control range and the power to the lamp has stabilized for a predetermined time period. The predetermined time period can be a default value or can be determined by a user.
摘要:
An optical scanning device for generating a data signal representative of an object which is scanned comprising a light source for illuminating the object; an imaging assembly for projecting imaging light from the object onto an image plane; a plurality of linear photosensor arrays positioned at the image plane for generating light sensing signals indicative of the intensity of light in different spectral regions impinged thereon; a transparent plate positioned in adjacent overlying relationship with the photosensor arrays; a plurality of filter coatings disposed on different regions of the transparent plate in alignment the plurality of photosensor arrays for filteringly transmitting imaging light in the predetermined different spectral regions to the different photosensor arrays.
摘要:
A document scanner is disclosed wherein means are provided to dynamically compensate for any changes in document illumination intensity that may occur as a document is scanned. The compensation method and apparatus operates to measure the intensity of light that is reflected from a target area that borders an edge of the document being scanned. The target area is a narrow, elongated, area that extends in the scan direction. The target area is of a color to approximate the document's background area, i.e. the document's nonimage area. Since the target area is of a continuous and uniform color tone, any variation in the quantity of light that is reflected from the target area is caused by a variation in the intensity of illumination thereof by the scanning light source. The method and apparatus of the invention controls the scanning light source so as to maintain the light reflected from the target area at a substantially constant magnitude.
