Abstract:
An image forming device that executes an image forming program for real-time mechanical control and another program, using a single cache memory for the image forming program and said another program. The image forming device includes: a cache lockdown unit that executes a cache lockdown to lock down a storage area of the cache memory that stores at least a portion of the image forming program necessary for image formation processing; and a print unit that executes the image formation processing while the storage area is locked down.
Abstract:
To provide an electronic device that is capable of displaying a warning indication of urging a replacement of a memory at an optimal timing. A system control calculate a warning indication threshold value based on a ratio of a value to a TBW (guaranteed write capacity), the value being a multiplication of a sum of the data write quantity per day that are defined for a for-system partition and a for-each function partition of the SSD and specific days (for example, 3 months) before the sum of write quantities reach the TBW. The system control part, which controls data write on the aforementioned partitions, causes a panel part to display the warning indication of urging a replacement of the SSD when a remaining write capacity of the TBW reaches the warning indication threshold value.
Abstract:
An image forming apparatus including: a storage device composed of a plurality of storage sections for storing a job data to be input; an image forming section for performing an image formation based on the job data having been stored in the storage device; and a control section configured to control a first mode for processing an independent job data, and a second mode for processing a plurality of job data in parallel, wherein the control section is configured to control in such a manner that a storage section, in said plurality of storage sections, to be used in the first mode differs from a storage section to be used in the second mode.
Abstract:
To provide an image processing apparatus that changes methods of storage to a memory depending on image data to be input and improves overall image processing performance, as well as a control method of the image processing apparatus. To accomplish this, the present image processing apparatus changes methods in which input image data is stored depending on whether scanner image processing is to be performed by a system control unit that comprehensively controls the image processing apparatus or performed outside of the system control unit. Specifically, when performing scanner image processing in the system control unit, since input image data is to be input directly from a CCD, the image data is stored frame-sequentially in a memory. On the other hand, when performing scanner image processing outside of the system control unit, input image data is stored dot-sequentially in a memory.
Abstract:
In an optical scanner, when an emission control unit varies a period at which image data is output from an output buffer of the emission control unit in order to correct a sub scan magnification of a LED array and a vacant region of an input buffer of the emission control unit ceases to exist, a buffer control unit temporarily stores the image data in a vacant region of a memory of an image correcting unit, and transfers the image data temporarily stored in the memory to the input buffer when the vacant region is generated in the input buffer.

Abstract:
An image forming apparatus is provided with a processor, a storage unit for storing a program and data, a function unit for performing functional operations; and an interactive input/output unit. The storage unit includes first storage areas, second storage areas, and third storage areas, which are hierarchized. The program causes the processor to display specified information allotted to the first storage areas on the interactive input/output unit. If one first storage area is selected, information of the second storage areas related to the selected first storage area is displayed on the interactive input/output unit. If one second storage area is selected, information of files in the third storage areas included in the selected second storage area and the names of processes to be performed to the files are displayed on the interactive input/output unit. If the file and process are selected, the process is performed to this file.
Abstract:
An image forming apparatus is disclosed. The image forming apparatus includes plural image output units, plural output image data converting units disposed for the corresponding image output units for converting image data of a predetermined format into image data of a format for the corresponding image output units, a first memory unit which is used in common for storing image data in processes by the image output units and the output image data converting units, and a memory area adjusting unit which adjusts a memory area in the first memory unit for memory area obtaining requests from the image output units and the output image data converting units.
Abstract:
Disclosed is an image processing apparatus which prevents repetitive storage of identical image data, and efficiently uses a storage area. More specifically, a facsimile apparatus (8) has a network interface, and also has a display unit (4c) as a display means for displaying an image as a user interface, a main controller (3) including a memory as a storage means for storing image data, a display controller (4b) as a generating means for generating an image to be displayed on the display means, by using the image data stored in the memory, and an HTTP server as a transmitting means for transmitting the image data stored in the memory, in response to a browsing request input via the network interface.
Abstract:
An image forming device includes an operating system to execute any of a plurality of programs. The image forming device comprises a rewritable memory which has a virtual memory area managed by the operating system and an image memory area used to store image data. A memory assignment unit assigns one of the virtual memory area and the image memory area of the rewritable memory for execution of a program of the plurality of programs upon starting up of the image forming device.
