Abstract: An image reading apparatus includes an image reading unit, a character stamp information reception unit receiving the input of character stamp information, a manuscript character information extraction unit, and an information-added image data generation unit. The information-added image data generation unit generates information-added image data serving as data where meta-information and a stamped image are caused to make a set. The meta-information is information where the character stamp information received by the character stamp information reception unit is added to manuscript character information extracted by the manuscript character information extraction unit.

Abstract: An image processing system readily provides a client PC with preview of a target image for printing or transmission. In accordance with a request from a client PC, a server requests a MFP to generate base image data by reducing the size of an original image and to transmit information of image editing contents available for the MFP to the server. In accordance with the requests from the server, the MFP subsequently provides the base image data and necessary information to the server. Then, the server provides the client PC with a preview window to display the image data obtained by reducing the size of the base image data and an image editing window to display image editing contents available for the MFP.

Abstract: An image processing apparatus has a storage unit for storing uncompressed data, a compression processing unit for performing lossless compression and lossy compression on the uncompressed data, a memory controller for reading the uncompressed data from the storage unit and writing compressed data compressed by the compression processing unit and a control unit for controlling transfer of the uncompressed data stored in the storage unit to the compression processing unit, wherein the compression processing unit has one DMA and simultaneously executes the lossless compression and the lossy compression, and wherein the control unit uses the DMA to successively transfer a rectangular region, constituted by a predetermined number of pixels in a main scanning line direction and a predetermined number of pixels in a sub-scanning line direction, of the uncompressed data from the storage unit to the compression processing unit for each rectangular region, and after uncompressed data on a main scanning line is transfer

Abstract: The present invention provides an image processing apparatus including: an image reading section for reading a document image; a particular image determining section for determining whether or not a particular image is included in image data read by the image reading section; an image processing section for processing the image data; and a resolution converting section for changing a resolution of the image data to be transferred to the particular image determining section, wherein the resolution converting section lowers a pixel frequency of the image data to be transmitted to the particular image determining section so as to perform simple processing. The lowered pixel frequency slows down processing speed of the image data and thereby improves determination accuracy.

Abstract: An information displaying and printing system that reduces the time to wait for printing of content displayed on a displaying apparatus to complete is provided. An image forming apparatus transmits an image data and an identification information of the image data stored in a registration information database to a displaying apparatus. The displaying apparatus receives an image data and an identification information of the image data, displays the image data, and transmits a print request with the identification information to the image forming apparatus. The image forming apparatus searches for an identification information coinciding with the identification information received from the displaying apparatus by referring to the registration information database, reads the image data from the registration information database, and prints the image data.

Abstract: An apparatus includes a CCD that reads a script image, an analog front end unit (AFE) that adjusts the offset and the gain of an image signal and A/D-converts the image signal, an image processing IC that applies image processing such as shading correction, input gamma correction, color correction, MTF correction, output gamma correction to the digital image signal, and a spread spectrum frequency IC that generates a spread spectrum clock based on a source oscillation clock, wherein the former block of the image processing unit is driven with the source oscillation clock and the latter block is driven with the spread spectrum clock. The image signal is transferred asynchronously from the former block to the latter block through an external memory controller.

Abstract: An image processing system readily provides a client PC with preview of a target image for printing or transmission. In accordance with a request from a client PC (information transmission direction i), a server 2 requests a MFP 1 to generate base image data by reducing the size of an original image and to transmit information of image editing contents available for the MFP 1 to the server 2 (information transmission direction ii). In accordance with the requests from the server 2, the MFP 1 subsequently provides the base image data and necessary information to the server 2 (information transmission direction iii). Then, the server 2 provides the client PC with a preview window to display the image data obtained by reducing the size of the base image data and an image editing window to display image editing contents available for the MFP 1 (information transmission direction iv).

Abstract: There are provided an information processing apparatus capable of reducing power consumption more than ever without deteriorating processing efficiency in the apparatus as a whole, an image forming apparatus, and a method for controlling the information processing apparatus. When the operation mode is in a sleep mode or an energy save mode at the time of receiving a facsimile data by a FAX modem, an instruction is made not to an image processing chip but to an IO chip to perform image processing for the received facsimile data. The IO chip performs the image professing using an LCDC (Liquid Crystal Display Controller). During this time, main control sections such as an SoC is remained in the non-energized state.

Abstract: A DMA-mode data processing apparatus is provided which enables high-speed data processing and efficient use of a memory bus. For DMA circuits that perform at least one of data write into a memory and data read from a memory, a switch SW is disposed which is operated in accordance with an instruction of a CPU, and memory data lines and command signal lines of a first DMA circuit and a second DMA circuit can be connected through lines based on the instruction of the CPU. As a result, while one DMA circuit performs the data write into the memory or the data read from the memory, the other DMA circuit can acquire the data and can transfer the data to another address of the memory or transfer the data to input/output apparatuses.
