preferred embodiment thereof, given by way of non-limiting example, and with reference to the accompanying drawings in which: - Figures 1a and 1b illustrate the calibration phase of a possible embodiment of the method according to the first aspect of the invention; FIGS. 2a and 2b illustrate the display phase of a possible embodiment of the method according to the first aspect of the invention; FIG. 3 is an exemplary architecture for the implementation of a possible embodiment of the method according to the first aspect of the invention; FIG. 4 is a schematic representation of the various steps of a possible embodiment of the method according to the first aspect of the invention. In the following we will take the example of the display of images of a mobile phone proposed by an online store type website.

The invention is however not limited to this specific example, but extends more generally to the visualization of any target object on any type of display device. The invention is advantageously applicable to any e-commerce store offering for sale articles whose actual size does not exceed that of a computer screen. But the invention also applies to the visualization in real size of products larger than a computer screen, the user can actually use the scroll functions vertical / horizontal to view the entire product. In the following, the preferred example of the display of an image of a target object (for example a mobile phone) representing, when resized and displayed according to the invention on a display device, the following is also shown: target object at its actual size. But the invention is not limited to this preferred example, and extends more generally to displaying an image of a target object representing this object in a size having corresponding proportions (for example a factor or a reduction factor) resized in accordance with the invention on an image of a reference object. According to a preferred embodiment, the method according to the invention makes it possible to display a target object (mobile phone) at real size, after performing a calibration using an image of a reference object. Referring to Figure 3, there is shown a client station C having a display device 1. This is for example the computer that the user uses to connect to an e-commerce site. It is more precisely through an internet browser that the user accesses all the web pages proposed by e-commerce site, these pages being stored on a server S. The server S includes a web application 4 loaded information processing. In particular, the web application 4 can be formatted to calculate, among other things, the dimensions of the images to be displayed, and to generate the web pages that the client wishes to display according to the reference data (target object, data of the standard, etc.). ). The server S also comprises an application server 5 which offers basic services (processing of the JSP pages, web server, etc.), for example a servlet container. The server S further comprises a repository of the terminals R in the form of a database containing all the information (dimensions, technical characteristics, images of the different views, etc.) on the terminals offered for sale by the e-site. -trade.

Note that for ease of use, the data is stored in a database. But this data can just as easily be stored in a CSV, XML, or other configuration file. The images are preferentially stored in a 3o tree of the server S. But they could just as easily be

stored in a database (BLOB or other), or in a file server type WebDav. One possible embodiment of the invention is as follows. Calibration phase This phase is shown diagrammatically in FIGS. 1a and 1b, and bears the reference A in FIG. 4. The user accesses (see block 100 in FIG. 4), through his internet browser, at a web page presenting a resizable area (Javascript, Flash, Java Applet, ...) in which an image of a reference object 3 is displayed. The reference object is typically a standard size everyday object. This is for example a coin, a CD, a DVD, etc. The preferential reference object here is a bank card, a common object at the disposal of a large part of the population (in the form of a credit card or withdrawal card for the youngest), which has a standard size of 86x54 mm. It could just as well be a withdrawal card, life card, corporate badge, ...

It should also be noted that the bank card offers the advantage of being of substantially equivalent size to that of a cell phone with a common flap. This implies that by using this reference object rather than a smaller one, the target object will be resized with greater accuracy.

At initialization, the image 3 displays the reference object (bank card) on the display device 1 in a fixed size, preferably larger than the actual size. The known data are as follows: - the dimensions of the actual bank card (Height and Width in millimeters);

7

the dimensions of the original image 3 of the bank card (Height and Width in pixels) as displayed in the resizable area. By placing the actual reference object on the area displayed on the screen, or by comparing the area displayed on the screen with the knowledge that it has about the actual size of this reference object, the user will be able to calibrate the system, by resizing the area accurately (block 110). For example, the user affixes his bank card in the upper left corner of the map displayed on the screen, and resizes the image 3 1 o until it is the same size as the map qu It has been arranged on the screen The resizing performed by the user of the image of the reference object is illustrated by the solid arrow bearing the reference 6 in FIG. 1, and the resized image of the object. This resizing of the image of the reference object is, for example, performed in the same way as the resizing of a window in the Windows operating system. the user may be asked to validate it, the server S will then memorize the resizing performed (block 130) Once the calibration operation has been carried out, the server S knows: the dimensions of the real bank card (Height and Width in millimeters); imensions of the original credit card image 3 (Height and Width in pixels) as initially displayed in the resizable area; dimensions of the resized image of the bank card (Height 'and Width' in pixels) as displayed in the resizable area at the end 30 Visualization phase

This phase is shown diagrammatically in FIGS. 2a and 2b, and bears the reference BH in FIG. 4. The user then accesses, via his internet browser, a web page presenting the target object 2, here a mobile phone, which he wants to visualize (block 200). For example, by clicking on a link 7 offering the display Actual size, the user accesses another page offering the different colors and views of the target object. The server S then calculates the dimensions of the target object to display 1 o in its actual size (block 210). For this purpose, an image of the target object is automatically resized in proportions corresponding to the resizing performed by the user on the image of the reference object during the calibration phase. For this purpose, the server S retrieves the information it needs from the repository R, namely the dimensions (block 220) and the images (block 230) of the object in question. Finally, a web page is generated which displays the image at the right dimension 2 'according to the dimensions calculated by the server (block 240). The automatic resizing of the image of the target object is illustrated by the arrow 8 in FIG. 2b, so that an image 2 'of the real size target object is finally displayed on the device 1. above, the resizing is done on the client side by the web browser according to dimensions calculated by the server S, which offers the following advantages in particular: the load of the server is limited because the resizing of the image is processed by the client (for example, the image is resized automatically by hovering over the image of the view you want to see).

a single image (per view) of sufficiently precise resolution so that the resized image is of sufficient quality regardless of the resolution of the customer's screen, is necessary. According to an alternative embodiment that minimizes the load of the client, the server generates images with adequate dimensions and a web page containing a link to the image in question. Advantageously, the method according to the first aspect of the invention is implemented during a user's browsing session on a site accessible by a telecommunication network, typically on an e-commerce site, and the user's resizing proportions of the reference object's image is saved in a session variable, which session variable is used during the session to automatically resize any proposed target object images on said site that the user wishes to view. In such a way, in particular, said proportions will be used for the display of all the images of the mobile phones that the user wishes to view. The session variable can also be saved in a cookie, or cookie, so that the reference data can be retrieved by the user during a future visit to the online sales site. In other words, during a subsequent browsing session, the session variable is used for the automatic resizing of any target object image proposed on said site that the user wishes to view.

Various calculation examples are described below for resizing the image of the target object. In order to realize this resizing, the following information is for example necessary: ù The size of the reference object on the screen in pixels (RefPix) ù The size of the reference object in millimeters (RefMM) û The size of the object to display in millimeters (Width, Height, Thickness) To resize an image representing a front view of the mobile phone, two reference data, the Width and Height of the phone in millimeters, are used to calculate the dimensions L and H of the phone in pixels in the image resized to real size: L = (L_RefPix * Width) / L_RefMM H = (H_RefPix * Height) / H_RefMM To resize an image representing a closed profile view of the mobile phone, two reference data, the thickness and the height of the phone in millimeters, are used to calculate the dimensions L and H of the phone in pixels in the image resized to full size.

L = (L_RefPix * Thickness) / L_RefMM H = (H_RefPix * Height) / H_RefMM Other representations of the mobile phone are of course envisaged in the context of the invention. As examples, it is possible to display a real-size representation of the mobile phone in an open front view, in a three-quarter open profile view, in an open front view, and so on. The invention is also not limited to the visualization of the target object by means of 2D images, but also extends to the visualization of the target object by means of a 3D representation which is resized according to the invention to offer the user a real-size 3D perception of the target object. It is also common that e-commerce sites allow the user to view side by side different objects of the same type, thus offering a comparison function of the products offered for sale. The invention can be implemented in the context of such a comparison of different target objects, in order to present side by side several resized images according to the invention to represent different telephones to their real size. The user is then better able to compare phones.
