Abstract:
1. An image processing device comprising: an image reading component configured to read an original document image with a plurality of image sensors arranged in series, and to divide pixel signals corresponding to one main scanning line read out into N blocks, and to output pixel signals corresponding to one main scanning line by outputting data from each of the N blocks; a detecting component configured to detect presence or absence of a factor of black line on a platen or white board from the pixel signals output from the image reading component; and a series of error pixel correcting processing components each configured to receive the data from a corresponding block among the data output from the N blocks by the image reading component, and to correct error pixels brought about by the factor of black line the detecting component detects, wherein when the detecting component detects the factor of black line at a boundary between a Kth block and a (K−1)th block of the N blocks, the Kth error pixel correcting processing component notifies the (K−1)th error pixel correcting processing component of neighboring pixel information about the error pixels, and the (K−1)th error pixel correcting processing component corrects the error pixels at the boundary in response to the neighboring pixel information notified and the data from the (K−1)th block.
