Abstract:
Provided is an image forming apparatus that speeds up the auto color mode. The image forming apparatus includes a document reading unit that reads a document including a plurality of pages and outputs image data and can determine whether the document is a color document or a monochrome document. In the document read by the document reading unit, when monochrome pages of the first specific number of pages or more continues in the same job, a document determining unit predicts that the subsequent page is also determined to be a monochrome document. When the document is predicted by the document determination unit to be a monochrome document, an image processing unit performs monochrome image processing for the monochrome document on the image data immediately after reading.
Abstract:
A reference device includes an operation section, a function collecting section, a function selection screen generating section, and a remote connection section. The function collecting section receives a function list from another device connected to a network. The function selection screen generating section generates a function selection screen including a function of the reference device and a function present only in the other device by comparing the function list received from the other device to a function list of the reference device and displays the function selection screen on the operation section. When the function present only in the other device is selected in the function selection screen, the remote connection section remotely connects the other device in which the selected function is present to the operation section of the reference device.
Abstract:
An image processing apparatus has a plurality of image processing functions, executes processing based on an OS as an operation system, and includes an OS memory and a control device. The control device functions as an allocating device, a determination device, and a release device. The allocating device allocates, on the OS memory, image processing memories used for image processing, for the image processing functions, respectively. The determination device determines, based on respective past usage statuses of the image processing memories allocated for each of the image processing functions, regions unlikely to be used, of the image processing memories. The release device, upon occurring memory shortage in the OS memory, releases the regions of the image processing memories determined by the determination device to resolve the memory shortage.
Abstract:
Provided is an image forming apparatus that suppresses degradation of performance of processing up to completion of printing while suppressing the occurrence of moire. A data-compression unit stores identification data indicating the presence or absence of periodicity obtained by analyzing printing data, and printing data correlated with the identification data in a first memory area of a RAM. A color-conversion-processing unit that performs a speculative process, causes printing data that has undergone a color conversion process corresponding to printer printing to be stored in a second memory area of a RAM. A screen-processing unit that performs a speculative process, performs an AM screen process on printing data. In addition, a system-control unit causes the image-forming unit to move from a printing pre-start position to a printing start position based on a determination result of a printing color in a color conversion process corresponding to a first printer printing by the color-conversion-processing unit by a speculative process.
Abstract:
An image forming system includes a portable terminal device, an image forming apparatus, and a marker registration circuit. The image forming apparatus prints a marker associated with location information of a user who has instructed execution of printing on a recording medium. The portable terminal device includes an information acquisition circuit and a position notification image output circuit. The information acquisition circuit photographs a marker printed on a recording medium using an imaging device so as to acquire the location information registered in the marker registration circuit, and the location information is associated with the marker photographed by the imaging device. The position notification image output circuit outputs a position notification image that notifies a position corresponding to the location information acquired by the information acquisition circuit to an output device.
Abstract:
An augmented reality operation system includes: an image-taking device, a display device, an MFP, an augmented reality processing section displaying, on the display device, a synthetic image obtained by synthesizing an operation image illustrating an operation section for operating the MFP with a taken image taken by the image-taking device, and an operation reception section receiving operation on the operation section in the operation image. The operation reception section, based on a position (on the synthetic image) of a hand taken by the image-taking device and a position of the operation section on the synthetic image, receives the operation on the operation section.

Abstract:
An image forming apparatus includes an image reading unit, an image forming unit, an acceptance unit, a paper transporting unit, a mode selecting unit, and a control unit. The image reading unit includes a document transporting device, a loaded-document detecting unit, a document table, a document holder, and a placed-document detecting unit. The mode selection unit can select a first mode in which paper is transported at the start of image reading operation and a second mode in which paper is transported after the image reading operation. If the loaded-document detecting unit detects that a document has not been loaded in a loading position and the placed-document detecting unit detects that a document has not been placed on the document table, the control unit controls the mode selection unit to select the second mode and controls the image reading unit to read an image on the document table.
Abstract:
An image processing device reduces an image in a sub-scanning direction at a reduction factor of ½N (N>1) and includes one or more ASICs each of which performs image reduction at a reduction factor of 50%. When the one or more ASICs perform the image reduction processing in N stages each at the reduction factor of 50%, one of the ASICs performs an i-th stage of the image reduction processing at 50% (N−1≧i≧1) and stores resulting image data into a buffer memory that is equal in size to ½i of one band. Then, one of the ASICs performs an (i+1)-th stage of the image reduction processing at 50% on the image data acquired through the i-th stage of the image reduction processing and stores resulting image data into a buffer memory that is equal in size to ½i+1 of one band.
