  • Publication number: 20190320187
    Abstract: [Object] To prevent an inappropriate processing parameter from being used in a case in which an image that may be expressed by various expression methods is handled. [Solution] Provided is an image processing device including: a control unit that decides a processing parameter for image processing performed on an image on the basis of at least one of a transfer function related to conversion between light and an image signal that is applied to the image or a color range that is applied to the image; and a processing unit that executes the image processing using the processing parameter that is decided by the control unit.

  • Publication number: 20190308428
    Abstract: A printing apparatus having a body, a cover, a pair of supporting parts, a locking member, and an engaging portion, is provided. At least one of the pair of supporting parts is a movable supporting part. The locking member arranged on the movable supporting part is movable between a locked position and an unlocked position. The engaging portion arranged in a container compartment engageable with the locking member being at the locked position. The locking member at the unlocked position when the cover is open is separated from the engaging portion. In a process where the cover is moved to be closed, a protrusive portion in the cover contacts to be pressed against a contact portion in the locking member, causing the locking member to shift from the unlocked position to the locked position to be engaged with the engaging portion.

  • Publication number: 20190281267
    Abstract: [Object] To provide satisfactory image quality irrespective of signal expression schemes. [Solution] Provided is an image processing device including: a coding unit that codes an image acquired on the basis of a transfer function related to conversion between light and an image signal; and a control unit that controls coding processing executed by the coding unit, on the basis of the transfer function. The control unit may control a coding amount assigned to each partial region of the image in the coding unit, on the basis of the transfer function. The control unit may control a prediction residual coding amount or a mode coding amount for mode selection when the image is coded in the coding unit, on the basis of the transfer function.

  • Patent number: 7606512
    Abstract: An image forming apparatus, such as a printer, may have a horizontally-loaded drawer containing, for example, a toner cartridge or an image forming unit having toner. The apparatus may have an opening through which the drawer is inserted, and a cover over the opening. The cover may include two or more protrusions to assist in forcing the drawer into place as the cover is closed. The cover may include a first protrusion that is closer to the cover's hinge, and a second that is farther from the hinge than the first. The first protrusion may also be longer, extending further from the cover, than the second, so that during the closing operation, the first protrusion makes contact with the drawer before the second. The points of contact on the drawer may be angled and/or curved such that the force exerted by the protrusions directs the drawer horizontally and, if desired, downwardly towards an operating position.

  • Patent number: 7561825
    Abstract: A discharge tray is provided on a predetermined surface of an image forming unit for receiving a recording medium discharged from the image forming unit. The image reading unit is disposed in confrontation with the discharge tray for reading an image from an original document. The coupling portion is disposed at a first position on the image forming unit. The coupling portion couples the image reading unit with the image forming unit, allowing the image reading unit to pivotally move about a first pivoting axis. The image reading unit is pivotally movable between a closed position for covering the discharge tray and an open position for exposing the discharge tray. The pivoting-restricting portion is disposed at a second position different from the first position. The pivoting-restricting portion restricts pivotal movement of the image reading unit past the open position in an opening direction.

  • Patent number: 7429039
    Abstract: A hinge device is configured that when a cover is opened, a support-section-side pivot shaft is guided upward by a fixed-section-side guide groove; and a fixed-section-side pivot shaft is guided while being restricted in downward movement by a support-section-side guide groove which tilts in accordance with a pivot operation of the cover. As a result, occurrence of interference between a frontward edge of the cover and an upper face of a document ejection tray can be prevented without causing the frontward edge to move lower than its position in a face-down state. In addition, chattering of the cover during the opening/closing operations can also be prevented.
