Abstract
An image read processing apparatus includes an image reading unit movable relative to a medium surface on which an image to be read is recorded. The image reading unit reads the image on the medium surface by repeating a line scanning in a direction substantially perpendicular to the direction of movement of the image reading unit relative to the medium surface during a period of time when the direction of the relative movement is a predetermined direction, and outputs image data representative of the read image and movement data concerning the relative movement. The apparatus further includes a detector for detecting the direction of the movement of the image reading unit relative to the medium surface on the basis of the movement data. When the detected movement direction is a direction substantially different from the predetermined direction, an other-direction moving distance is determined by which the image reading unit has been moved in the different direction. When a blank region including no image data continues spanning a predetermined distance and over during the movement of the image reading unit in the predetermined direction, a distance of the blank region defined by a moving distance of the image reading unit is changed on the basis of the other-direction moving distance.
