Abstract:
A screen display control device includes: a compression unit which compresses input image data in a line unit; a rewritable image memory to which the compressed data compressed in the line unit by the compression unit is written in non-synchronization with a reading process; a decompression unit which decompresses the compressed data periodically read from the image memory in synchronization with screen display to restore original image data; a display unit which displays an image of the image data decompressed and restored by the decompression unit; a buffer memory which temporarily maintains compressed one-line data compressed by the compression unit; and a writing/reading control unit which controls the processes of writing and reading the compressed data to and from the image memory and processes of writing and reading the image data to and from the buffer memory. When the processes of reading and writing the compressed data of the same line to and from the image memory compete with each other, the writing/reading control unit controls the image data of the line to be written so as to be maintained in the buffer memory. The writing/reading control unit controls the process of reading the compressed data of the line maintained in the buffer memory upon reading the compressed data of the line.

Abstract:
An exemplary image capture device includes a camera module, a buffer including a first unit and a second unit, a processor, and a memory. The camera module is configured for capturing images by forming corresponding electric signals. The first unit of the buffer is configured for buffering electric signals formed in a period that the image capture device is used to preview before capturing. The second unit of the buffer is configured for buffering electric signals formed after the image capture device is fired to photograph. The processor is configured for processing the electric signals in the first unit into preview digital images when preview, and processing the electric signals in the second unit and those still buffered in the first unit into final digital images after the image capture device is fired. The memory is configured for storing the final digital images outputted from the processor.

Abstract:
For achieving high-speed continuous shooting and increasing the number of shots that can be picked-up continuously, within a limited buffer memory size, an image pickup apparatus is provided with a function of carrying out a first process of storing output data from an image pickup element on a first memory area and a function of carrying out a second process of processing data placed on the first memory area and storing the processed data on a second memory area, and is configured to perform the first and second processes in parallel.
Abstract:
A memory management device enables to effectively use a memory which permits its stored data to be erase only in blocks. A facsimile apparatus is arranged to temporarily store sending information and received information in the memory and them to send or received the information. The facsimile apparatus includes a flash memory whose data is allowed to be erased only in blocks and a storage unit for storing the sending or the received information in its own blocks if the sending or the received information is stored in the flash memory.
Abstract:
A system and method are provided for adaptively allocating random access memory (RAM) in an multifunctional peripheral (MFP) device with a plurality of components. The method comprises: supplying an interface; and, in response to interface prompts, selecting the allocation of RAM for MFP features or components. Typically, the MFP device includes fax, scanner, printer, and copier components, and the method further comprises selecting the allocation of RAM for MFP components selected from the group including fax, scanner, printer, or copier. The method further comprises: selecting the allocation of RAM for MFP features selected from the group including post script (PS) documents, printer control language (PCL) documents, tagged image file format (TIFF) documents, or portable document format (PDF) documents. Supplying an interface includes supplying front panel graphical user interface (GUI) to present RAM allocation options, and selecting the allocation of RAM for MFP functions in response to interface prompts includes allocating portions of RAM in response to GUI prompts. Alternately, the MFP is connected to a computer workstation with a display. Then, supplying an interface includes receiving a request from a browser loaded on the computer workstation and, from an embedded web server in the MFP, supplying a GUI to the computer workstation display, presenting RAM allocation options.
Abstract:
A multi-function apparatus includes a basic memory, a socket, and a controller. The basic memory includes at least a first image memory area for a copying function and a second image memory area for a facsimile function. The socket connects an add-on expansion memory. The controller arranges memory assignments of the basic memory in accordance with a first memory map to perform operations of the copying and facsimile functions when the expansion memory is not mounted to the socket. The controller rearranges the memory assignments of the basic memory and of the expansion memory with an effect of expanding the first and second image memory areas in accordance with a second memory map to perform the operations of the copying and facsimile functions when the expansion memory is mounted to the socket.
Abstract:
A multifunction apparatus has a receiver that receives a picture signal and a converter that converts the picture signal received by the receiver into image data. A memory is provided for storing the image data obtained through conversion by the converter. The memory is usable also for an operation other than an operation related to the conversion by the converter unit. A detector detects an amount of memory space available in the memory. A conversion mode changer changes a mode of conversion by the converter unit, on the basis of result of the detection by the detector unit. The multifunction apparatus improves the quality of image data and efficiently and fully uses the memory, thereby reducing the memory capacity required and reducing the manufacturing costs.
