Method and device for presenting digital images on a low-definition screen
First Claim
Patent Images
1. A method for displaying a digital image having a relatively high definition and contained in a database of a server on the screen of a display device, comprising the steps of:
- a) on request coming from the display device requiring the display of a digital image in the database, determining the type of screen associated with the display device on which the image will be received;
b) before transmission, applying to the image to be transmitted, a transformation of the image definition, the transformation being a function of the type of display screen that has been determined in step a);
c) transmitting the image modified by the transformation; and
d) displaying this modified image on the screen of the display device;
wherein at least two different images are transmitted to the display device, the images being sufficiently similar so as to increase the visual perception of grey levels by sequential alternating display of the distinct images received.

Abstract
In order to present digital images on different types of screens, and especially on low definition screens, the system provides a server that is adapted for receiving messages coming from at least one display device, and a table for recognizing the type of display device with which the server is communicating. The server performs a transformation for adapting the definition of the image that is transmitted to the type of display screen that is recognized.

3. A method for displaying a digital image having a relatively high definition and contained in a database of a server on the screen of a display device, comprising the steps of:
-
a) on request coming from the display device requiring the display of a digital image in the base, determining the type of screen associated with the display device on which the image will be received; b) determining on the image at least one principal area of interest containing an object; c) detecting the characteristics of the object contained in said at least one principal area of general interest is detected to at least the area of principal interest; d) applying to at least the area of principal interest a transformation which is a function of the characteristics of the object in order to adapt the characteristics of the image of the object contained in said at least one area of principal interest to the given type of display screen, to at least the area of principal interest; e) applying to at least the area of principal interest a transformation which is a function of the definition of the given type of display screen in order to adapt the definition of the object contained in said at least one area of principal interest to the characteristics of the display screen; f) transmitting the image modified by the transformation; and g) displaying said area of principal interest on the screen of said given type.
