  • Patent number: 7027655
    Abstract: Methods and systems for compression of digital images (still or motion sequences) are provided wherein predetermined criteria may be used to identify a plurality of areas of interest in the image, and each area of interest is encoded with a corresponding quality level (Q-factor). In particular, the predetermined criteria may be derived from measurements of where a viewing audience is focusing their gaze (area of interest). In addition, the predetermined criteria may be used to create areas of interest in an image in order to focus an observer's attention to that area. Portions of the image outside of the areas of interest are encoded at a lower quality factor and bit rate. The result is higher compression ratios without adversely affecting a viewer's perception of the overall quality of the image.

  • Publication number: 20040148335
    Abstract: The present invention relates to methods and apparatus for requesting and receiving print jobs over a communications network. In particular, the present invention enables a user to obtain print jobs at a location which may be unspecified, and which may be remote from the source of the print job. A spooling server is used to store a print job received via the network from a print job source. A printer polling device, which may be used at a location remote from the client device, is capable of polling the spooling server via the network to identify whether any print jobs associated with the printer polling device are available for printing at a printer currently associated with the polling device. The spooling server need not initiate contact with the printer through a firewall, since it is polled by the printer polling device. Thus, network security is maintained.

  • Patent number: 6647149
    Abstract: Methods and apparatus are provided for securely transmitting and processing digital image data for display. The invention provides for decomposing, compressing, and scrambling digital image data and forwarding the decomposed, compressed and scrambled image data to a destination where the image data is decompressed, re-composed, and descrambled prior to display. In particular, digital image data is scrambled before or after being compressed and is subsequently descrambled after being decompressed and prior to display such that unauthorized use of the image content is prevented. The invention can be used in conjunction with most standard block-based image compression algorithms such as JPEG as well as some types of wavelet transform based systems.

  • Patent number: 5625712
    Abstract: A method and apparatus are provided for compressing image data to enable the storage thereof in a limited amount of memory available in an imaging system. The image data is rasterized into a plurality of scan lines representing at least a portion of an image. Each scan line comprises a sequence of pixels. The scan lines are compressed in a first coding step. A determination is made as to whether the amount of data contained in the compressed plurality of scan lines exceeds the available storage capacity of the memory. If so, the scan lines are further compressed in a second coding step to reduce the amount of data therein. The second coding step can be successively repeated using more tolerant coding thresholds until the amount of data remaining no longer exceeds the available storage capacity of the memory.

  • Patent number: 5619624
    Abstract: Apparatus is provided for managing a plurality of output devices to generate images from graphic image files. Each of the output devices is associated with a respective control system which includes a first queue for storing the graphic image files. The graphic image files are rasterized to develop raster image data that is stored in a second queue. A job controller selects images represented by data in the graphic image files stored in the first queue for rasterizing on a real time basis. The job controller is responsive to parameters of the graphic image files, the second queue, and the associated output device to manage the flow of image data from the first queue to a raster image processor (RIP) and from the RIP to the output device via said second queue.

  • Patent number: 5615314
    Abstract: An interface provides rasterized data to an imaging device such as a color copier or laser printer. Rasterized image data received from a raster image processor is compressed and stored in an output queue until the imaging device is ready to receive an image represented by the data. A data output path between the output queue and imaging device communicates the rasterized image data to the imaging device. The compressed rasterized image data is decompressed within the data output path as the data is being communicated to the imaging device. Throughput of the imaging device is maximized by actuating the device to operate in a multiple copy mode while rasterized image data for different image pages is successively communicated to the imaging device. An abort command prevents the imaging device from processing extraneous substrates when running in a multiple copy mode.

  • Patent number: 5389985
    Abstract: An imaging system such as an image recorder or scanner is provided with a rearview cathode ray tube. A transparent viewport of optical quality is provided along an optical axis of the CRT which is perpendicular to the CRT faceplate and generally centered with respect to the image area. The electron beam used for scanning the images is placed off-axis with respect to the CRT screen. A deflection control system compensates for spherical distortion and for the keystone effect that results from the off-axis placement of the electron gun. The structure of the present invention eliminates halation, thereby improving the dynamic range and contrast achievable for imaging and/or scanning purposes. The phosphor layer used in the CRT is made substantially thicker than in conventional CRTs, thereby reducing blemishes and improving uniformity, resolution and light output. The partial sharing of electron beam and optical paths enables more compact imaging and scanning systems to be provided.
