Title:
IMAGE-READING APPARATUS AND IMAGE-READING METHOD
Document Type and Number:
WIPO Patent Application WO/2016/147832
Kind Code:
A1
Abstract:
An image-reading apparatus (1) provided with: N sensor chips arranged in a first direction, each of the sensor chips having a plurality of imaging elements arranged in the first direction; N optical systems in which reduced images of N read ranges aligned in the first direction on a document are individually formed in the N sensor chips; and an image-processing unit (4) in which the position, in the first direction, of the overlapping areas of adjacent read ranges is determined using image data generated by the N sensor chips, the magnification of the read image and a compositing position are obtained from the position in the first direction thus determined, an image process is performed to correct the magnification in the first direction of the image data of the N read ranges, and the image data of the N read ranges subjected to the image process is combined to generate composite image data (D44), the image data being image data of the overlapping areas, the overlapping areas being areas in which there is an overlap between the adjacent read ranges in the image data of the N read ranges, and the compositing position being a position in which two items of image data are combined.
