  • Patent number: 7075681
    Abstract: A system and method for reducing the volume of data necessary to represent an image by utilizing tiling and masking techniques is disclosed. Initially, an image described by raster content having an original number of bits per pixel is provided. The image is divided into tiles such that each of the tiles represents a portion of the image. Then, for each of the tiles, the following steps are performed: (a) the colors in the tile are identified; (b) the required number of masks are compared to a threshold number of masks to determine if data reduction by using masks is worthwhile; (c) if the required number of masks is less than the threshold number of masks, a representation of the tile is generated using fills and/or masks; and (d) if the required number of masks is greater than or equal to the maximum number of masks, a representation for the tile using the original format and number of bits per pixel or a smaller index is generated.

  • Patent number: 7054040
    Abstract: First and second reading modules read first and second signals in the main scanning direction of the image of a document. The scanning module includes a carriage for relatively moving the first and second reading modules and the image of the document in a sub-scanning direction to make the modules scan the image. A scanning-control-condition selecting module selects scanning control conditions of the scanning module in accordance with a plurality of read magnifications preset as read magnifications of the document by the first and second reading modules. A first setting module sets the scanning control conditions to a plurality of control conditions in accordance with the read magnification of the first reading module. A second setting module sets the scanning control conditions to a plurality of control conditions in accordance with the read magnification of the second reading module.

  • Patent number: 7042600
    Abstract: A method of eliminating strobing in successive scan lines of an image includes determining a nominal scan line time and an associated scan line integration time for the image sensor. A nominal illumination light source output period is determined for the illumination source. In order to ensure that the scan line integration time is equivalent to an integer number of illumination source light output periods, at least one of the nominal scan line integration time and the nominal illumination source light output period is adjusted. A clock signal, derived from the pixel clock, drives both the frequency circuitry of the lamp drive circuit and the integration time of the image sensor. The present method provides a reliable means for eliminating lamp strobing independent of the relative phasing of the lamp oscillation phase with respect to the start of each scan line integration.

  • Patent number: 7012720
    Abstract: A method of effacing zipper image, applicable to scan a document by a scanner with a stagger charge-coupled device. The nth (n is a positive integer) pixel obtained by scan on a scan line at which the zipper image is produced is subtracted by the (n+1)th pixel obtained by scan on the scan line. The absolute value of the result is then compared to a critical value. If the result is smaller than the critical value, the nth pixel is the nth pixel modified as the nth pixel after process.

  • Patent number: 7002714
    Abstract: An autofeeder and media object digitization system. A receptacle for media objects is coupled to align a first wall with a clip to hold the media object. A suction device forming part of the first wall sucks a media object against a suction plate. The suction plate then moves the media object into engagement with the clip. The clip is driven to move the media object past a scanning window. A release lever or the clip is triggered to release the media object after it has passed the scanning window.

  • Patent number: 6972878
    Abstract: The present invention provides a scanner including a housing defining two mounting holes. An elastic rib is located beside each of the two mounting holes to provide a retaining action. A paper cover is pivotally mounted on the housing and has two locking hooks. Each locking hook is mounted in a respective mounting hole of the housing. Thus, the height of the paper cover can be adjusted according to the variation of depth of the locking hook in the mounting hole. In addition, the locking hook is retained by the elastic rib and the catch plate of the mounting hole, such that the paper cover cannot be removed easily, thereby preventing the paper cover from being lost.

  • Patent number: 6961153
    Abstract: There is provided an image inputting apparatus which allows various processing while minimizing originals to be reset in an original feeder. The image inputting apparatus is provided with a scan processing command for operating only an image reading section and a feed processing command for operating only an original feeder section with respect to an external control unit such as a computer. When the external control unit issues the feed processing command, an image input control section of the image inputting apparatus receiving the command recognizes that the command is a command for controlling the original feeder section and instructs an original feeder monitoring control section to feed the original. Receiving the instruction, the original feeder monitoring control section controls the original feeder section to feed one original onto a platen.

  • Patent number: 6958833
    Abstract: An image input scanner includes a linear array of photosensors to record images, such as in a digital copier or facsimile. A subset of the photosensors can be selected, depending on a particular situation, for recording images, while other photosensors are deselected. In this way, recording of “blank” image data, such as would be caused when photosensors in the array are not exposed to a sheet passing relative to the array, is avoided. In one embodiment, the array includes a plurality of local clock drivers, each clock driver controlling image data readout from a subset of photosensors. When a subset of photosensors are selected for a given situation, only the clock drivers associated with the selected photosensors are activated.
