Abstract: An image forming apparatus includes rendering units that refer to rendering data composing partial regions within a page as input data, generates image data by merging the rendered results, and uses the image data as output data. Each rendering unit holds a rendering position of processing that is currently executed by itself, and detects a rendering position of processing that is currently executed by another rendering unit. When rendering for a partial region that is currently processed is completed, a control unit detects a rendering position held in another rendering unit, and changes allotment of a partial region serving as the next rendering target of its rendering unit so as to reduce the difference between time periods until its rendering unit and another rendering unit complete rendering for the next partial region.

Abstract: In an image processing apparatus which generates an input signal when a mobile information terminal contacts a display surface and makes a wireless communication with the contacting mobile information terminal, it is difficult to make an appropriate display by discriminating whether a contact object is a mobile information terminal or a user's finger. To accomplish this, when a mobile information terminal (200) is placed on a touch panel (104), this placement is recognized based on a wireless communication response (701), and a processing menu for the terminal is displayed. On the other hand, if the user's finger (300) is placed, since no wireless communication response (701) is detected, it is recognized that the contact object is not the mobile information terminal (200), and a general manipulation menu is displayed.

Abstract: An information processing apparatus that achieves both power supply to an external device and information processing. Power supply capability to be presented to the external device is determined based on a state of the information processing apparatus. Power is supplied to the external device, based on a request from the external device as to the power supply capability to be presented to the external device. In a case where the state of the information processing apparatus has changed, the power supply capability to be presented to the external device is changed based on the changed state.

Abstract: To accomplish this, when an image processing apparatus determines with reference to a parameter associated with the image processing apparatus that allocations of storage capacities to a first storage unit which stores block images obtained by dividing image data in a page unit and a second storage unit which stores tile images obtained by dividing each block image are required to be changed, the apparatus changes the allocations of the storage capacities in correspondence with the parameter, and also changes division sizes of the block images and the tile images in accordance with the changes in storage capacities.

Abstract: A method is provided for controlling an image forming apparatus provided in a room managed by a management apparatus capable of managing an entry or exit state of a participant who attends a conference and configured to process a print job received from a client computer. The method includes determining whether the room is used by a participant of a conference relating to the print job transmitted from the client computer, outputting the print job in a case where it is determined that the room is used by the participant of the conference relating to the print job, and restricting an output of the print job in a case where it is determined that the room is not used by the participant of the conference relating to the print job.

Abstract: In a case that a first processor assists a second processor, the first processor issues a request for execution of a type of image processing assigned to the second processor, receives information specifying data on which the first processor performs the type of image processing assigned to the second processor, and performs the type image processing assigned to the second processor on the data specified by the information. According to this, it is possible to execute auxiliary processing by a light-loaded processor for a heavy-loaded processor in correspondence with loads of plural processors.

Abstract: Conventionally, pixel data are converted into the tile sequence. According to this invention, span information or run-length information during conversion into pixel data from vector data such as a display list converted from a page description language is converted into the tile sequence before rendering into pixel data. This can greatly reduce the amount of data temporarily stored for conversion into the tile sequence.

Abstract: An image forming apparatus capable of ensuring security of discharged printouts and preventing noise made by the operation of the image forming apparatus from becoming obtrusive to a user. The post-processing apparatus switches the operation mode of post processing to one of a normal operation mode and a quiet operation mode, and opens and closes a sealing door. Current limiting circuits switch the operation mode to the quiet operation mode before sealing of the door is released by a sealing drive circuit in response to an instruction from the user.

Abstract: An image processing apparatus divides inputted image data into blocks of a predetermined size, applies a plurality of image processes to each block, and determines whether a block includes image data with an attribute of not executing predetermined image processes. As a result of the determination, the predetermined image processes are not applied to the block if it is determined that the block includes the image data with the attribute of not executing the predetermined image processes. However, the predetermined image processes are applied to the block if it is determined that the block does not include the image data with the attribute of not executing the predetermined image processes. The image data with the attribute of not executing the predetermined image processes is vector image data, and the predetermined image processes are rendering, resolution conversion, and image compression.

Abstract: When the data is divided into blocks each having a set block size, and image data includes an object which extends over a plurality of blocks, the object is divided based on object information associated with the object. The object information of the divided object is re-set based on the object information associated with the object divided into blocks. Block vector image data are generated using the object having the re-set object information.

Abstract: In a case that a precedent queue to supply data to be processed does not include data to be processed, a processor D switches its operation mode to an auxiliary mode to perform a part of processing assigned to a processor A, and issues a request for execution of the part of the processing assigned to the processor A, to the processor A. In response to the request, the processor A notifies the processor D of information to cause the processor D to perform the part of the processing assigned to the processor A, and the processor D performs the part of the processing assigned to the processor A in accordance with the notified information.
