An image forming apparatus which implements a plurality of functions includes: storage with a prescribed storage area; an operating system which implements at least some of the functions by allocating a part of the prescribed storage area for a plurality of processes and executing the processes; and a storage area managing section which predicts an amount of consumed memory in response to generation of a job and determines whether or not the amount of consumed memory is allocable to the job in the prescribed storage area. The job is a processing target for the image forming apparatus. The amount of consumed memory is used for processing the job by the image forming apparatus. When determining that the amount of consumed memory is not allocable, the storage area managing section ends at least one process which is not used to process the job to make the amount of predicted memory allocable.

An image processing apparatus generates a binary image from a multivalue input image, detects a character region and a non-character region from the binary image, and clips regions surrounding each of characters included in the detected character region as character clipping rectangles. The apparatus determines, on the basis of a black pixel density of the binary image included in the character clipping rectangle, whether or not the character clipping rectangle is a character region and determines, on the basis of a number of pixels included in the character clipping rectangle determined to be a non-character region, whether or not the character clipping rectangle determined to be a non-character region is a character region.

Disclosed is an image processing apparatus, including a receiver that receives a setting of a job; a reader that optically reads an original; a memory that stores the image data; and a hardware processor that instructs the external device to store the image data to be edited, and edits the image data page by page by using the page edit function of the external device, wherein when a temporary storing job for temporarily storing the image data in the memory is executed, the hardware processor judges whether a setting of a setting item for an edit of the image data page by page is changed, and in case that the setting of the setting item is changed, the hardware processor carries out a preceding transmission process in which the image data stored in the memory is transmitted to the external device and is stored in the external device.

An information processing device including a communication unit configured to communicate with an external device on an Internet, the external device being configured to generate a single print job based on a single file received from the information processing device and provide the generated print job to a printer, and a controller configured to select one or more first-format files, each of which is in a first format configured such that an individual file in the first format contains a single page, cause a converter to convert the selected one or more first-format files into a single second-format file, the second-format file being in a second format configured to allow an individual file in the second format to contain a plurality of pages, and control the communication unit to transmit the single second-format file acquired through the conversion, to the external device.

A transmitting and receiving system includes a first information processing apparatus and a second information processing apparatus. The first information processing apparatus includes a first cache memory, and the second information processing apparatus includes a second cache memory. The second information processing apparatus is configured to transmit and receive information to and from the first information processing apparatus. When transmission information to be transmitted from the first information processing apparatus to the second information processing apparatus is stored in the first cache memory of the first information processing apparatus, the first information processing apparatus transmits partial information that is included in the stored transmission information to the second information processing apparatus or transmits identification information that identifies the transmission information to the second information processing apparatus.

An image processing system includes a first flip-flop bank and a second flip-flop bank, and a control system configured to control JPEG processing of image data. The control system is further configured to, during a first period, use one of the first or second flip-flop banks as a write bank and the other of the first or second flip-flop banks as a read bank and, during a second period, alternate the use of the first and second flip-flop banks as the write bank and the read bank. Further, the control system is configured to, after alternating the use, initialize the read bank to zero.

A printer receives print setting information from a server, and executes a one-set process repeatedly in accordance with the print setting information. The one-set process includes: a specifying process for specifying a page number which is to be requested to the server, a transmitting process for transmitting the request including the specified page number to the server, a storing process for storing a partial data in the memory in a case where the partial data is received from the server, a printing process for printing using the partial data, and a releasing process for releasing an area in the memory.

Further, the control system is configured to, after alternating the use, initialize the read bank to zero.

A history generating apparatus includes an image generating section, an image reading section and a history generating section. The image generating section generates a bitmap first image and generates initial attribute information indicating attributes of respective pixels of the first image. The image reading section reads an image based on the first image formed on paper so as to generate a bitmap second image. The history generating section separates the second image into image regions by attribute indicated by the initial attribute information, performs image processing on each of the image regions according to the attribute and combines the image regions so as to generate a history image.
