  • Patent number: 8351090
    Abstract: An image processing apparatus determines a direction of document placement relative to a scanning direction based on a direction of a shadow region in an input image when a line sensor having a light receiving element performs a scan and an image read from a book document by a reading apparatus is input. When the direction of the binding portion of the document is determined to be along a longitudinal direction of the line sensor, an image of a region read by the light receiving element of the line sensor from reflected light undergoing specular reflection from the document is detected based on the amount of variation in luminance between adjacent pixels in the read image of the book document. Luminance of the image corresponding to the region is corrected.

  • Patent number: 8351050
    Abstract: A wavefront-aberration-measuring device measures wavefront aberration of a to-be-tested optical system and includes a diffraction grating that splits light transmitted through the optical system, a detecting unit that detects interference fringes produced by beams of the split light, an arithmetic unit that calculates the wavefront aberration from the detected interference fringes, an image-side mask insertable into and retractable from an image plane of the optical system, and an illuminating unit that incoherently illuminates the image-side mask. The image-side mask has an aperture with a diameter larger than ?/2NA, where ? denotes a wavelength of the illuminating unit and NA denotes a numerical aperture of the to-be-tested optical system. The arithmetic unit calculates the wavefront aberration of the optical system from the interference fringes detected with the image-side mask being retracted from the image plane and the interference fringes detected with the image-side mask being in the image plane.

  • Patent number: 8346716
    Abstract: The present invention can realize easy transition from a task managed by a To-Do list to a workflow. When an unprocessed task stored in the To-Do list database is converted by an instruction into the workflow in the client software, a document management system of the present invention extracts a workflow definition including an activity corresponding to an unprocessed task to be converted by the instruction and notifies a client software of the workflow definition. When the client software selects the workflow definition, server software creates an instance of the workflow corresponding to the selected workflow definition, and applies information about the task to be converted, to the activity corresponding to the task to be converted in the instance of the workflow.

  • Patent number: 8342648
    Abstract: To provide an inkjet head which includes high-density nozzle rows and which does not easily cause an ejection failure due to adhesion of ink mist around ejection orifices when a high-density image of a secondary color is printed with a small number of paths. An inkjet head includes at least two or more types of nozzle rows that eject different amounts of ink. When A is the cross section, with respect to an ink supplying direction, of an ink supply path from each ejection orifice to a supply port and L is the length of the ink supply path, the value of A/L differs between the two or more types of nozzle rows. The nozzle row of which the value of A/L is small is disposed outside an area between the nozzle rows that eject a largest amount of ink and that are arranged next to each other.

  • Patent number: 8346155
    Abstract: After a sheet has once passed through a punching position where punching processing is performed, a conveyance roller pair conveys the sheet backward to the punching position. A lateral registration detection sensor detects a side edge position of the sheet in a width direction. When a sheet processing apparatus corrects the side edge position of the sheet by controlling a shift unit configured to move the sheet in the width direction so as to correct the side edge position of the sheet, the sheet processing apparatus sets a shifting amount of the sheet to a value that is a predetermined amount greater than a shifting amount required to correct the side edge position of the sheet according to the side edge position of the sheet detected by the lateral registration detection sensor. After the sheet has passed through the die hole in the backward movement toward the punching position, the sheet processing apparatus sets the shifting amount to the required value.
