Abstract:
An image processing apparatus includes a plurality of compression units and a switching unit. The plurality of compression units compress image information by different compression methods. The switching unit extracts plural pieces of color information from pieces of color information which constitute the image information in a color space expressing the image information, and selects one of the plurality of compression units in accordance with hue angles of the plural pieces of extracted color information.
Abstract:
A sheet conveying apparatus that conveys a sheet serving as a recording medium and effectively reduces energy consumption includes a movable sheet supporting device configured to support sheets, a sheet size detecting device configured to detect a size of the sheets by detecting a location of the sheet supporting device, a gap detecting device configured to detect a gap between the sheets and the sheet supporting device, and a reporting device configured to notify an operator of a gap detected by the gap detecting device.
Abstract:
An image data processing device has an image identifying unit and a file generating unit. The image identifying unit identifies a common image that is common to each page and a non-common image that differs from page to page on the basis of inputted image data including a plurality of pages. The file generating unit generates separate files of the common image and the non-common image.
Abstract:
An automatic grading method has processes of reading, identifying and calculating. A process of reading a document is performed and the document has one or more answers. A process of identifying the answers from the document is also performed. A process of calculating a score of the document based on a score of each answer is performed.
Abstract:
An image forming apparatus includes a reversing unit which reverses and feeds recording material fed from a fixing device, and a guiding device including first and second guide members facing each other to form a part of a first conveying path in which a recording material with a toner image fixed thereto is conveyed to the reversing unit from the fixing device. The second guide member forms, in cooperation with a third guide member, a part of a second conveying path in which the recording material is conveyed to an outside of the main body of the image forming apparatus. The first and second guide members are movable between a sheet guide position in which the first and second guide members guide the recording material along the first and second conveying paths, and a sheet jam removing position in which each of the first and second conveying paths is opened for removal of a jammed sheet. A feeding device feeds the recording material fed from the fixing device through the first and second conveying paths, respectively, and a displacement device displaces the first and second guide members to the sheet guide position or the sheet jam removing position in cooperation with the reversing unit.
Abstract:
A color television cathode ray tube which comprises a phosphor screen formed of (A) a red-emitting phosphor selected from the group consisting of europium-activated rare earth metal oxide and europium-activated rare earth metal oxysulfide; (B) a green-emitting phosphor selected from the group cosisting of a mixture of copper-activated zinc sulfide and gold-activated aluminum-coactivated zinc sulfide and copper- and gold-activated zinc sulfide; and (C) a blue-emitting phosphor of silver-activated zinc sulfide, and wherein the green-emitting phosphor contains 0.005 to 0.02% by weight of copper and 0.005 to 0.15% by weight of gold based on the total amount of the green-emitting phosphor; and current running through the cathodes of electron guns for exciting the red-, green- and blue-phosphors can be made to have a substantially equal amount for the respective electron guns.
