ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a system and process for writing by hand on a digital image, and in particular a system and process which allow a prerecorded digital image to be combined with personalized graphic elements.
BACKGROUND OF THE INVENTION
In order to personalize a photograph with a message or a drawing, a person can write with a pen directly onto the photographic paper. However, it is difficult to get the ink to adhere to the photographic paper and the result obtained is often very mediocre.
Digital imaging has made image personalization easier. There are techniques for writing on digital images such as those for instance described in Patent Application EP 843 461. EP 843 461 describes a process for combining a prerecorded digital image with text or personalized graphics. The process includes writing the desired text onto a support which is then scanned. The scanned text is then inserted at a predetermined place in the digital image. Such a technique does not allow users to write a message wherever they want on the photograph because the addition is inserted at a predetermined place in the digital image. Moreover, users cannot see the result of their work immediately afterwards, so if it is not suitable, they are not aware of it until after scanning and combining the message and the image. Such a method is therefore neither very practical in use nor very intuitive.
There are other more intuitive devices for adding personalized graphic elements to prerecorded images. Such devices are constituted, for example, by a graphic tablet, like the tablet model PL300 marketed by the Wacom company, and a pen especially designed to write on the tablet, as represented in FIG.

. When the first tip of the pen
30
is applied to the tablet
20
, data concerning the application of the pen is recorded. This data is especially the coordinates of the position of the pen
30
on the tablet
20
, the pressure with which the pen
30
is applied to the tablet
20
, or even the angle of inclination of the pen
30
. Also at its other end such a pen has an eraser function. Using this data, image processing software such as for example Photoshop® can be configured to display a point corresponding to each coordinate of the pen recorded, as represented in FIG.

In certain photographic points-of-sale where this type of tablet is made available to customers so that they can add personalized elements to a photograph, it is desirable that several customers can use such a tablet without having to manage the other controls required for its use, such as supplying a prerecorded image to the tablet, or printing a prerecorded image with personalized elements. This management is preferably done by one or more persons operating the point-of-sale. The devices described above do not allow the use of the tablet to be separated from the management of the other controls.
SUMMARY OF THE INVENTION
An object of the invention is to provide a new system and a process that allows a user to hand write on a photographic type image in a very simple and intuitive way and, further allow another person to manage the other controls.
The invention relates to a system for combining a prerecorded digital image with hand written graphic elements that comprises: at least one computer for managing links between various parts of the system; at least one means for supplying a prerecorded digital image to the system, and a peripheral that comprises: a means for, on the one hand, displaying the prerecorded image and, on the other hand, digitally recording data corresponding to the hand written graphic elements; and a processor for managing the functions of the means for displaying the prerecorded image and for communicating with the computer.
The invention further relates to a process for combining a prerecorded digital image with personalized graphic elements. The process comprises the steps of: acquiring a prerecorded digital image, displaying the prerecorded digital image on a screen; writing and recording a personalized graphic element directly on the screen; and publishing the prerecorded digital image combined with the personalized graphic elements.
The invention further relates to a system for obtaining a prerecorded digital image with hand written graphic elements. The system comprises: at least one computer which manages links between various parts of the system; at least one image supplier which supplies a prerecorded digital image to the system; and a peripheral which comprises: a display element which displays the prerecorded image and which records data corresponding to the hand written graphic elements; and a processor which manages functions of the display element and which communicates with the at least one computer.
