Abstract
An image processing device includes a displacement amount acquisition unit to acquire an amount of displacement of an image, a geometric correction unit to apply image processing to an input image according to the amount of displacement to perform geometric correction of the input image, a write timing control unit to control write timing of the input image according to the amount of displacement to perform correction of the input image, and a correction mode determination unit to select a first correction mode or a second correction mode according to the amount of displacement when the image is printed-out. With the first correction mode, the geometric correction unit corrects the input image in a first and a second direction. With the second correction mode, the geometric correction unit corrects the input image in the first direction and the write timing control unit corrects the input image in the second direction.
