  • Patent number: 8922792
    Abstract: In an apparatus connected to a plurality of input devices, in the case of a browsing mode of images stored in a device from which images are input, a user is allowed to select, in parallel, from the images stored in the input device and images showing interfaces capable of connecting to the other devices. Further, if an image indicating an interface is selected, the interface changes to an input mode of image data. Thus, the user is allowed to input image data from the other input devices without returning to the setting screen of an input device in such a mode.

  • Patent number: 8520043
    Abstract: An optical writing apparatus includes a light source device that includes a VCSEL having an alignment of at least two channels in a sub scanning direction configured to emit plural light beams in a block. A deflector deflects the plural light beams toward an image bearer that forms an image by changing a line speed of image formation. A control device decreases a number of light beams by turning off a prescribed same number of the channels symmetrically from the both ends of the alignment in accordance with the line speed.

  • Patent number: 8456686
    Abstract: According to this invention, the date range can be intuitively designated by designating up, down, left, and right directions, and images stored in a storage medium can be easily restricted to images which may be subjected to printing. In order to restrict images stored in a memory card on the basis of the date, a region for inputting the start date of the date range is displayed at the upper portion of a display window on a display device, and a region for inputting the end date is displayed at the lower portion. One of the regions is designated and selected with up and down direction keys. A date in the selected region is changed with left and right direction keys. Images having storage dates between the start date and the end date are decided as printing target candidates.
