Abstract: An image reading apparatus has: electrodes that come into contact with a medium during transport; charge detection circuits, each of which corresponds to one of the electrodes; a reader, and a controller. The controller executes inclination inference processing for calculating the inclination of the medium with respect to a transport path as an inferred inclination value according to a signal from each charge detection circuit, inclination detection processing for deriving the inclination of the medium with respect to the transport path as a detected inclination value according to the result of reading by the reader, and correction value deriving processing for storing a correction value based on the difference between the detected inclination value and the inferred inclination value in a storage section. In inclination inference processing with the correction value stored in the storage section, the inferred inclination value is calculated in consideration of the correction value.

Abstract: An image processing system comprises a first image processing apparatus and a second image processing apparatus. The first image processing apparatus obtains image data and transmits, to the second image processing apparatus, the obtained image data and information relating to the image data. The second image processing apparatus receives the image data and sets a condition for determining whether the image data is the image data to be processed, and determines whether or not the received image data is the image data to be processed, based on the set condition and the information. The second image processing apparatus executes, when it is determined that the received image data is the image data to be processed, image processing on the image data, based on the information and stores a result of the execution of the image processing.

Abstract: Provided is an image reading system capable of improving the image quality of a document in which text and images are mixed in the same page. A camera captures a document in page units to obtain captured image data. A document reading unit is an image scanner having a higher resolution than the camera. An area classifying unit classifies the captured image data captured by the camera into areas for each content. An area selecting unit selects, for each classified area, whether to output captured image data based on the area classification and the state of the captured image data. An image processing unit processes the captured image data or the scanned image data for each area, and outputs or deletes the data as area data. The document output unit collects the processed area data, reconstructs the data into document data, and outputs the document data.

Abstract: Provided is an image reading system that can disperse and improve the image quality of a document. The document reading unit reads a document page by page and outputs it as image data. The area classification unit classifies the read image data into area data for each content. The blockchain creation unit creates a block in which identification information is added to the classified area data, and sequentially calculates and includes the previous hash value of the previous block, thereby creating the blockchain of the document. The image processing unit in information processing apparatus processes or deletes the area data for each received block. The block acquisition unit acquires a block processed by the information processing apparatus. The document output unit collectively reconstructs the block that is acquired into document data and outputs the document data.
