Information processing apparatus and method for blockchain-based document management

An image processing apparatus generates a first image by adjusting luminance so as to preserve a signal value on a high-luminance side among signal values acquired by reading a document by a scanner, and detects a position of a region corresponding to the document in the generated first image. The image processing apparatus further generates a second image by performing adjustment so as to increase luminance of a pixel contained in the first image, and crops a document image from the generated second image based on the detected position of the region corresponding to the document.

An information processing method includes calculating at least one difference value between a pixel value of a target pixel in an input image obtained by capturing a document image and a pixel value of a corresponding pixel in a shade component image at coordinates identical to those of the target pixel. The shade component image represents shade components of the input image. The shade components depend on an image capture environment. The method further includes correcting the pixel value of the target pixel in the input image based on a correction rate to correct a shade component in the target pixel. The correction rate depends on at least one difference value associated with the target pixel in the input image.

This invention provides a technique of preventing a collision between an original document and a printing material on a conveyance path when an image forming apparatus executes both additional printing on the original document and printing on the printing material. In a case where both additional printing on an original document and printing on a printing material are executed, the image forming apparatus according to one aspect of the invention conveys a read original document to a transfer unit through a conveyance path commonly used for an original document and sheet, and prints an image to be added on the original document. After the original document is conveyed to the transfer unit through the conveyance path, the image forming apparatus feeds a sheet from a sheet feeding unit to the conveyance path, and performs copying on the sheet in the transfer unit.
