Abstract
With reference to any one of a plurality of images, the other images are moved by a distance greater than or equal to one pixel width in a main scanning direction and/or a sub-scanning direction. Then, the plurality of images are combined to form a composite image.
Claims7
An image processing apparatus comprising:
- an image detector having a plurality of pixels and configured to convert an optical image into an image signal to pick up the image signal as an image;
- a moving unit configured to move the image detector from a first position by a distance greater than or equal to a pixel width;
- a control unit configured to control the image detector and the moving unit such that a first image is picked up by the image detector at the first position, and that a second image is picked up by the image detector at a second position displaced from the first position by the distance greater than or equal to the pixel width;
- and
- a combining unit configured to combine the first image and the second image to form a composite image by changing, in coordinates of the composite image, coordinates of the second image to values corresponding to the distance.

A control method for controlling an image processing apparatus that combines a plurality of images obtained by an image detector to form a composite image, the control method comprising the steps of:
- causing the image detector to pick up a first image at a first position;
- causing the image detector to pick up a second image at a second position displaced from the first position by a distance greater than or equal to a pixel width of the image detector;
- and
- combining the first image and the second image to form the composite image by changing, in coordinates of the composite image, coordinates of the second image to values corresponding to the distance.
