Abstract

This device for processing video data (10) comprises at least one video image acquisition unit (14). The unit (14) includes means (32) for generating an initial video image, the video image being defined by a video data set. The device further comprises means for transmitting data between the image acquisition unit (14) and an on-board computer (16), and image-creator means for creating a useful video image from the initial video image. The image-creator means comprise means (34) for adjustably selecting at least a portion of the initial video image, the selected portion constituting at least a portion of the useful image.

Claims

1. A video data processor device for a motor vehicle, the device comprising at least one video image acquisition unit including means for generating an initial video image, the video image being defined by a video data set, means for transmitting data between the image acquisition unit and an on-board computer, and image-creator means for creating a useful video image from the initial video image, the device being characterized in that the image-creator means comprise adjustable selector means for selecting at least a portion of the initial video image, the selected portion constituting at least a portion of the useful image.

2. A device according to claim 1, wherein the video image acquisition unit includes means for forming an optical image having an angular field of view greater than 120°

, from which the initial video image is generated.

3. A device according to claim 2, wherein the means for forming the optical image comprise a fish-eye type lens.

4. A device according to claim 1, wherein the image-creator means include means for adjustably selecting at least two portions of the initial video image, the selected portions constituting at least two portions of the useful image.

5. A device according to claim 1, having two video image acquisition units, the useful video image being constituted by two portions selected respectively from the two initial video images generated respectively by the two video image acquisition units.

6. A device according to claim 2, wherein the image-creator means include means for adjustably selecting at least two portions of the initial video image, the selected portions constituting at least two portions of the useful image.

7. A device according to claim 3, wherein the image-creator means include means for adjustably selecting at least two portions of the initial video image, the selected portions constituting at least two portions of the useful image.

8. A device according to claim 2, having two video image acquisition units, the useful video image being constituted by two portions selected respectively from the two initial video images generated respectively by the two video image acquisition units.

9. A device according to claim 3, having two video image acquisition units, the useful video image being constituted by two portions selected respectively from the two initial video images generated respectively by the two video image acquisition units.
