Abstract
An image processing device is provided which corrects error pixels without using a line buffer even in the case of using an image sensor with a structure having a plurality of sensors arranged in series. It has a detecting component for detecting the presence or absence of a factor of black line and Kth error pixel correcting processing components each for receiving the Kth pixel signal among the pixel signals output in N divisions, and for correcting error pixels. When the factor of black line is detected at a boundary between Kth and (K−1)th division outputs, 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 (K−1)th pixel signal.
