Abstract

A method and devices for copying an image (2) from an electronic display (1) to an electronic paper (3), wherein said electronic paper (3) is held against an area (6) of the electronic display (1) for performing a copy action and that said electronic display (1) comprises identification means for determining the borders of the area (6), a copy set button included in said devices for initiating the copy action, circuits for establishing a wireless connection between the display (1) and the paper (3) and a processor (5) for reading image information from the area (6) of the electronic display (1) for sending the image information to the electronic paper (3) for the display of the image (2) comprised in said area (6) of the electronic display (1) on the electronic paper (1).

Claims

1. Method for copying an image (2) from an electronic display (1) to an electronic paper (3) having light displaying elements arranged in a cross point matrix, comprising the steps of:

setting the electronic paper (3) to request a copy from said electronic display (1),

establishing a wireless connection (7) between said electronic display (1) and said electronic paper (3),

placing an electronic paper (3) against the electronic display (1),

covering the electronic display (1) on at least a part of an area (6) including said image (2) to be copied with said electronic paper (3),

identifying in said electronic display (1) the borders of the area (6) to be copied,

demanding the copy action to be carried out,

processing, in said electronic display (1), data containing image information for said area (6) to be copied,

transmitting by means of said wireless connection the image information from the electronic display (1) to the electronic paper (3) and

displaying on said electronic paper (3) by means of said light displaying elements arranged in said cross point matrix a copy of the image (2) filling up said area (6) of the electronic display (1).

2. The method according to claim 1, further comprising the step of:

identifying the area (6) to be copied as the area, which at any time during the copy action until the demand of the copy action to be carried out is covered by the electronic paper (3),

3. The method according to claim 1, further comprising the step of:

storing in a memory (8) included in said electronic paper (3) said image information for later displays of said image (2) on the electronic paper (3).

4. The method according to claim 1, further comprising the step of:

processing in said electronic display (1) said image information for adapting semantic information, such as fonts and layouts, to characteristics of the electronic paper (3).

5. The method according to claim 1, further comprising the step of:

providing said image information as analogue video signals or as digital image signals.

6. The method according to claim 1, further comprising the step of:

performing said identification of the area (6) of the display (1) to be copied by means of light sensitive elements (15) included in the display (1).

7. The method according to claim 1, further comprising the step of:

performing said identification of the area (6) of the display (1) to be copied by means of a detection of a change of the electromagnetic field around the display (1) in the area (6) which has been covered by the electronic paper (3).

8. The method according to claim 1, further comprising the step of:

performing said identification of the area (6) of the display to be copied by means of micro-beacons (16) provided in a known pattern of the display (1).

9. The method according to claim 1, further comprising the step of:

aligning the copy of the image (2) to be displayed on the electronic paper (3) with the image (2) displayed on the electronic display (1) in relation to the horizontal and vertical direction of rows and columns of light emitting elements as provided on the image (2) of the electronic display (1).

10. The method according to claim 1, further comprising the step of:

displaying a copy of the image (2) as it will be displayed on the electronic paper (3) on a window of the electronic display (1) for at least some seconds.

11. An electronic display (1) having light sensing elements (15) arranged in a cross point matrix of a screen of said display, for receiving an electronic paper (3) held against said screen for performing a copying of an image (2) from said electronic display (1) to said electronic paper (3), characterized in that the electronic display (1) comprises transmitter and receiver circuits (14) included in the electronic display (1) for establishing a wireless connection (7) between the electronic display (1) and the electronic paper (3), identification means (15, 16, 17) for determining the borders of an area (6) of said screen covered by said electronic paper (3), a processor (5) for reading data representing the image displayed on said area (6) of said screen for a transmission of said data to the electronic paper (3) by means of said wireless connection.

12. The electronic display according to claim 11, wherein said identification means includes light sensing elements (15).

13. The electronic display according to claim 11, wherein said identification means includes electromagnetic field change detection means (17).

14. The electronic display according to claim 11, wherein said identification means includes micro-beacons (16) provided in a known pattern of the display (1).

15. An electronic paper (3) having light displaying elements arranged in a cross point matrix on a face of said electronic paper (3) and adapted to perform a copying of an image (2) from a screen of an electronic display (1) when said face of the electronic paper (3) is held against the screen of the electronic display (1),

characterized in that the electronic paper (3) is provided with:

transceiver circuits (13) included in the electronic paper (3) for establishing a wireless connection (7) between the electronic display (1) and the electronic paper (3),

processing means in a circuit (4) for receiving data representing the image (2) on said electronic display (1) from said transceiver circuits (13) and for re-establishing said image (2) on said face of the electronic paper (3).

16. The electronic paper according to claim 15, wherein said transceiver circuits (13) are integrated into the electronic paper (3).

17. The electronic paper according to claim 15, wherein said electronic paper (3) includes a memory (8) for storing the data representing said image (2) for the display of said image (2) at a later occasion.
