A signal processing device (10) uses first characteristic data detected from a sheet-like detection target by a first detection element (1) and second characteristic data detected from the detection target by a second detection element (2) and having (i) a characteristic that is different from a characteristic of the first characteristic data and (ii) a correlation with the first characteristic data. The signal processing device (10) includes an evaluation value generator (3) that generates, by using the correlation with the second characteristic data, an evaluation value determining whether the first characteristic data includes an unnecessary portion, and a correction amount determiner (4) that determines, by using the evaluation value, for correction of data determined by the evaluation value generator (3) to be the unnecessary portion, a correction amount for the first characteristic data.

An information processing system includes an image processing apparatus including first circuitry and an information processing apparatus including second circuitry The first circuitry of the image processing apparatus reads an application form with a scanner to generate image data, acquires electronic watermark data from the image data, acquires, from an integrated circuit card, first identification information of the integrated circuit card, and creates application data based on the application form. The second circuitry of the information processing apparatus communicates with the image processing apparatus via a network, and performs user authentication based on the first identification information of the integrated circuit card acquired from the integrated circuit card and second identification information of the integrated circuit card previously associated with identification information of the application form. The first circuitry of the image processing apparatus stops creating the application data when the user authentication fails.

An information processing apparatus includes a feeding unit that feeds a document placed on a document placement unit, a reception unit that receives an execution instruction, a first reading unit that reads an image of the fed document to generate first image data, a second reading unit that reads an image of a document placed on a platen to generate second image data, an execution unit that, based on the reception unit receiving a single execution instruction, executes first processing in which the first reading unit reads the image of the fed document to generate the first image data, and second processing in which the second reading unit reads the image of the document placed on the platen to generate the second image data, and a storage unit that executes processing for storing the first image data and the second image data.

An image processing device includes an image reader that reads an image, a first determiner that determines whether character crushing occurs when the image is binarized, a second determiner that determines a rate of a photographic region in the image, and a controller that performs conversion into monochrome N-gradation image data based on determination results of the first and second determiners.

An image forming apparatus includes a reading device and a controller. The reading device reads an image of a source document, and generates image data. The controller receives an input of the image data generated by the reading device. Further, the controller decides that the source document is a chargeable item, when image information indicating that the source document is the chargeable item, for which charging a usage fee corresponding to the source document to a predetermined third party is permitted, is included in the image data.

An electronic device and a document processing system both with cost saving function are disclosed. The electronic device performs a blank page counting process on a received first document file data containing blank pages, in order to generate cost information of non-blank pages and display it for reference. With the above electronic device, it is able to save the cost of outputting blank pages and avoid waste of paper to achieve the purpose of cost saving. The document processing system includes the above electronic device, which is connected to the document processing system via a network.

An image forming apparatus according to the present disclosure includes an image forming unit configured to form an image based on an image forming condition; a reading unit configured to read a test image on a sheet; a controller configured to: control the image forming unit to form the test image; obtain read data related to the test image output from the reading unit is formed; and update the image forming condition based on the read data. The controller operates in a first mode and a second mode, the first mode is a mode in which, the controller controls the image forming unit to form the image for the second sheet after the image forming condition is updated based on the reading data related to the test image.

A copying apparatus capable of calibrating a copy position comprises a scanning module scanning an original to obtain an original image; and a processing module being electrically connected to the scanning module and recognizing whether the original image contains an original mark corresponding to a template mark. If the original image contains the original mark, then the processing module generates print data for being printed out according to the original image and a position parameter of the template mark. A copying method capable of calibrating the copy position is also provided. Thus, the copy position can be calibrated according to the mark of the original to prevent the copy result from having a positional offset. Consequently, no positional offset occurs even if the original is copied multiple times based on the previous generation of original.

In a copy system includes an image recording apparatus and a reading apparatus. A controller of the image recording apparatus performs: controlling a recording device to record a particular code indicating communication information identifying a communication device of the image recording apparatus; receiving image data; and controlling the recording device to record at least one image based on the received image data. A controller of the reading apparatus performs: controlling a reading device to read at least one document to create image data; and analyzing the created image data and determining whether the created image data contains the particular code on a page-by-page basis. When determining that the created image data contains the particular code. The controller of the reading apparatus performs: obtaining the communication information indicated by the particular code; and transmitting a portion of the created image data to a destination identified by the communication information.
