ABSTRACT:
An image processing apparatus has a mechanism for setting a desired magnification of a reproduced image, a display for displaying the selected magnification, an optical system for forming an image on a transfer medium, and a control unit. The control unit controls the optical system so as to form the desired magnified image even when the setting of a desired magnification changes. The control unit can also include a first timer for effecting a timing operation based on a predetermined time irrespective of input magnification and a second timer for effecting a timing operation based on the input magnification with a predetermined time relation to the first timer. In addition, the apparatus can include a first device for directly setting a magnification for image formation corresponding to a position of a movable member in accordance with a converted digital value and a second device for setting a predetermined specified magnification irrespective of the position of the movable member, or a device for selecting a retained magnification or a magnification corresponding to the position to the movable member changed before completion of image formation, without changing the position of the movable member after the completion of the image formation.
