Abstract
A method and a device are for displaying images. A chain of a determined number of images is provided in a housing. Images are displayed by being positioned in a display area. Images are displayed in a determined number of steps corresponding with the number of images. The control device switches the drive device on and off for the purpose of positioning and displaying one of the images. The method and device include calculation of the steps with a parameter determined by the movement of the chain from a position close to a start to a position close to an end of the chain.

A method for displaying images, comprising:
- providing a chain of a predetermined number of images;
- providing a display area for displaying one image at a time;
- displaying the images by moving the chain in the display area and positioning the image in the display area;
- displaying the images of the chain in a predetermined number of steps corresponding with the predetermined number of images;
- calculating the predetermined number of steps in accordance with a parameter related to a length of the chain;
- and
- determining the parameter in accordance with the movement of the chain from a position close to a start of the chain to a position close to an end of the chain.
An image display device for displaying images, comprising:
- a housing including a display area adapted to display images;
- two substantially parallel rolls arranged in the housing and placed on either side of the display area, a chain of a number of images windable onto the rolls, each image positionable in the display area;
- a drive device configured to drive the rolls;
- and
- a control device coupled to the drive device and configured to switch the drive device on and off to position and display each image in the display area in a number of steps;
- wherein the control device is configured to determine a parameter related to movement of the chain from a position close to a start to a position close to an end of the chain, and the control device is configured to calculate the number of steps corresponding with the number of images in accordance with the parameter.
