    摘要： An image reading apparatus including: a paper supply section; a transporting path for transporting a document supplied from the paper supply section; a first sensor which reads an image on a first surface of the document from one side of the transporting path; a second sensor which reads an image on a second surface of the document from the other side of the transporting path; and an image processing section which is constituted so as to correspond to a first reading mode in which two sides of the document are read using the first sensor plural times, and a second reading mode in which two sides of the document are read using the first sensor and the second sensor, and which makes a registration position and direction of an output image in both the first and second reading mode the same.

    摘要： The invention provides an image reading apparatus includes a feeder that feeds a sheet, a transfer path on which the sheet fed by the feeder is transferred, a first reading unit that captures a first image on a first face of the sheet from one side of the transfer path to obtain first image data, a second reading unit that captures a second image on a second face of the sheet from the other side of the transfer path to obtain second image data, and a correction unit that substantially equalizes image density of the first image data and that of the second image data in a case where the first image and the second image are captured at a single transfer of the sheet through the transfer path.

    摘要： An image processing apparatus includes: a first determination unit that determines whether each of an image regions is for a vector image; a color number counting unit that counts the number of colors in the pixels of high-resolution image data; a frequency counting unit that counts a number of times where the difference between the colors of each of the pixels in the high-resolution image data and the colors of at least one pixel located around each of those pixels is greater than or equal to a threshold; a second determination unit that determines that the image region is not an image region for a vector image; and a generation unit that generates image data in which a process for rendering images in the image regions determined by the first determination unit to be image regions for vector images is defined by numerical values or numerical formulas.
