Abstract

The present invention is in the field of digital imaging. It relates to a method for determining the coordinates of a subject of interest in a digital image, so as to be able to then display this subject of interest on the screen of a terminal with low display capacity. The present invention enables, from the screen of a terminal with sufficient display capacity, at least one subject of interest in an original still digital image to be selected, and the coordinates of said subject of interest to be determined. The application of the present invention consists in preparing the display operation of subjects of interest of digital images on the screens of terminals with low display capacity.

Claims

1. A method for selecting and recording at least one subject of interest in an original still digital image, said method comprising the following steps:

a) perform a request for the original image from a terminal whose display capacity enables the display of said original image;

b) display the original image on the screen of the terminal;

c) select a subject of interest in the original image, displayed on the screen of the terminal;

d) automatically determine the coordinates of the subject of interest in the original image;

e) automatically load in a server the original image and the coordinates, in the original image, of the subject of interest;

f) automatically save in the server the original image and the coordinates of the subject of interest.

2. The method of claim 1, wherein the subject of interest is selected by a point, placed approximately in the main part of said subject of interest.

3. The method of claim 1, wherein the subject of interest is selected by a line segment, placed approximately in the main part of said subject of interest.

4. The method according to any one of the preceding claims, wherein the coordinates of the subject of interest in the original image, correspond to the pixels of the markers of said subject of interest.

5. The method according to any one of the preceding claims, wherein the selection of the subject of interest in the original image is performed close to the barycenter of several homogenous entities of the original image, said homogenous entities forming the subject of interest of said original image, and wherein the optimized modified image comprising the several entities of the subject of interest is displayed on the screen of the terminal with low display capacity.

6. The method of claim 5, wherein the selection of the subject of interest is performed by a line segment that covers at least partially each of the homogenous entities of said subject of interest.
