Abstract

A unit for an method of analyzing received image data to determine whether the received image data corresponds to a single-view or to multiple views is disclosed. The method comprises: dividing the received image data (200) into a number of structures (1-9) of data elements (224-234); computing a correlation between a first one (1) of the structures of data elements and a second one (2) of the structures of data elements; and establishing that the received image-data corresponds to multiple views on basis of the correlation between the first one of the structures of data elements and the second one of the structures of data elements.

Claims

1. A method of analyzing received image data to determine whether the received image data corresponds to a single-view or to multiple views, the method comprising the steps of:

dividing the received image data into a number of structures of data elements;

computing a correlation between a first one of the structures of data elements and a second one of the structures of data elements; and

establishing that the received image data corresponds to multiple views on basis of the correlation between the first one of the structures of data elements and the second one of the structures of data elements.

2. The method of analyzing as claimed in claim 1, wherein said method further comprises the step of:

establishing that the received image data corresponds to multiple views if the correlation is higher than a predetermined threshold.

3. The method of analyzing as claimed in claim 1, wherein said method further comprises the step of:

computing a further correlation between the first one of the structures of data elements and a third one of the structures of data elements and establishing that the received image data corresponds to multiple views if the further correlation is lower than the correlation between the first one of the structures of data elements and the second one of the structures of data elements.

4. The method of analyzing as claimed in claim 1, wherein said method further comprises the step of:

computing a sequence of further correlations between the first of the structures of data elements and respective further structures of data elements and establishing that the received image data corresponds to multiple views if the consecutive correlations of the sequence of further correlations are mutually related according to a predetermined pattern.

5. The method of analyzing as claimed in claim 4, wherein the particular layout of structures of data elements corresponds to a particular layout of structure of light generating elements of a display device which is arranged to receive the image data and which is arranged to generate a particular number of views which matches with the particular layout of structures of data elements.

6. The method of analyzing as claimed in claim 1, wherein the step dividing the received image data into the number of structures of data elements is based on selecting a particular layout of structures of data elements from a set of layouts of structures of data elements.

7. A non-transitory computer-readable storage medium encoded with a computer program to be loaded by a computer arrangement, said computer program comprising instructions to analyze received image data in order to determine whether the received image data corresponds to a single-view or to multiple views, the computer arrangement comprising processing means and a memory, the computer program, after being loaded, causing said processing means to carry out the steps:

dividing the received image data into a number of structures of data elements;

computing a correlation between a first one of the structures of data elements and a second one of the structures of data elements; and

establishing that the received image data corresponds to multiple views on basis of the correlation between the first one of the structures of data elements and the second one of the structures of data elements.

8. A view mode analyzing unit for analyzing received image data to determine whether the received image data corresponds to a single-view or to multiple views, the view mode analyzing unit comprising:

dividing means for dividing the received image data into a number of structures of data elements;

computing means for computing a correlation between a first one of the structures of data elements and a second one of the structures of data elements; and

establishing means for establishing that the received image data corresponds to multiple views on basis of the correlation between the first one of the structures of data elements and the second one of the structures of data elements.

9. A display device which is arranged to display multiple views on basis of received image data, the display device comprising:

receiving means for receiving image data;

light generating means for generating light on basis of the received image data; and

the view mode analyzing unit for analyzing the received image data to determine whether the received image data corresponds to a single-view or to multiple views, as claimed in claim 8.

10. The display device as claimed in claim 9 which is arranged to switch a portion of the display device between a first view mode and a second view mode, comprising optical means for transferring the generated light in dependence of an actual view mode of the portion of the display device, the actual view mode being either the first view mode or the second view mode, the optical means being controlled by the view mode analyzing unit.

11. The display device as claimed in claim 9, wherein said display device further comprises:

mapping means for mapping a first number of views into a second number of views, being different from the first number of views.
