Abstract

Aspects of the present invention include method and apparatuses that may utilize a digital video recording device with a screen control panel, for example, a touch screen control panel, to record digital video data with adjusted light compensation based on a selected object within a scene. For example, a user, using a touch screen control panel, may choose an object within a scene. Based on this selection, the digital video recording device may adjust the backlight compensation settings and camera angle to obtain a better image of the selected object. A user may select an object by touching the image of the object, tracing the selected object, or touching a number of reference points of the object. Then, depending on the user selection, the digital video recording device may take a snapshot, zoom in and take a snapshot, record the scene, or it may lock on the object and readjust and track the object as the object moves, while recording the scene.

Claims

1. A vehicle-mounted digital video recording device for capturing video data during an event comprising:

a storage medium;

a touch screen control panel; and

a processing device configured to record a scene, receive a user selection of an object within the scene and then automatically perform compensation in order to enhance recognition of the selected object within the scene.

2. The digital video recording device of claim 1, wherein the user selects the object using the touch screen control panel.

3. The digital video recording device of claim 2, wherein the user may select the object displayed on the touch screen control panel by touching the object or tracing the object with a stylus or a finger.

4. The digital video recording device of claim 1, wherein the digital video recording device is adapted to adjust backlight compensation settings to obtain an enhanced image of the selected object in response to the user selection of the object, wherein the selected object may appear more enhanced than other parts of the scene.

5. The digital video recording device of claim 1, wherein the digital video recording device is adapted to take a snapshot of the object based on a user action while recording the scene.

6. The digital video recording device of claim 1, wherein the digital video recording device is adapted to zoom in based on a user action while recording the scene.

7. The digital video recording device of claim 1, wherein the digital video recording device is adapted to adjust backlight compensation settings and lock on to the object, wherein the digital video recording device is adapted to follow and track the object while recording the movements of the object.

8. The digital video recording device of claim 1, wherein the digital video recording device is adapted to capture a still image of the object and transfer the image to an character recognition unit.

9. The digital video recording device of claim 1, wherein the processing device is further configured to extract data from an image of the object, retrieve information about the extracted data, and display the retrieved information on the touch screen control panel.

10. The digital video recording device of claim 9, wherein extracting the data comprises performing character recognition to extract a license plate number from a license plate and retrieving information comprises retrieving data from a remote database.

11. A method for recording video data with a vehicle-mounted digital video capturing device corresponding to an event comprising:

displaying a scene representing the video data on a touch screen control panel while recording the scene; and

performing compensation in response to a user selection of a particular object or area located within the scene in order to enhance recognition of the selected object in the scene.

12. The method of claim 11, wherein the user may select the object displayed on the touch screen control panel by touching the object or tracing the object with a stylus or a finger.

13. The method of claim 11, wherein the digital video recording device is adapted to take a snapshot based on a user action while recording the scene.

14. The method of claim 11, wherein the digital video recording device is adapted to adjust backlight compensation settings and lock on to the object, wherein the digital video recording device is adapted to follow and track the object while recording the movements of the object.

15. The method of claim 11, further comprising:

extracting data from an image of the object;

retrieving information about the extracted data; and

displaying the retrieved data on the touch screen control panel, wherein the extracting the data comprises performing character recognition to extract a license plate number from a license plate and retrieving information comprises retrieving data from a remote database.

16. A method for recording video data corresponding to an event, comprising:

displaying a scene representing the video data on a touch screen control panel;

locking on to an object or an area in response to a user selection, wherein the digital video recording device is adapted to follow and track the object while recording its movements; and

performing compensation in response to the user selection of the object in order to enhance recognition of the selected object in the scene, wherein the selected object may appear more enhanced than other parts of the scene.

17. The digital video recording device of claim 16, wherein the digital video recording device is adapted to zoom in and take a snap shot while recording the scene in response to the user selection of the object or the area.

18. The method of claim 16, wherein the digital video recording device is adapted to center the object or the area while the digital video recording device is recording the scene.

19. The method of claim 16, wherein the digital video recording device is adapted to adjust a camera angle in order to obtain an enhanced image of the selected object or the area in response to the user selection of the object.

20. The method of claim 16, wherein the user selects the object or the area using the touch screen control panel.
