Abstract

A playback apparatus (100) and corresponding method for playing back images. The apparatus comprising a controller (110) configured for executing the steps of: recognizing an object in an image being played back (320); obtaining a keyword (410) associated to the recognized object (340); and—searching for information based on the keyword (370).

Claims

1. Playback apparatus for playing back images in a program, the apparatus comprising a controller configured for executing the steps of:

downloading image data of objects in images of the program based on preliminary information about the program;

recognizing an object in an image being played back based on the downloaded image data;

obtaining a keyword associated to the recognized object; and

searching for information based on the keyword.

2. Playback apparatus as claimed in claim 1, wherein the controller is further configured for:

obtaining a plurality of keywords; and

enabling a user to select one of the keywords for searching.

3. Playback apparatus as claimed in claim 2, wherein the controller is further configured for:

recognizing a plurality of objects in the image being played back; and

obtaining the plurality of keywords by obtaining a keyword associated to each of the recognized objects.

4. Playback apparatus as claimed in claim 3, wherein the controller is further configured for:

indicating the object in the image associated to a highlighted keyword.

5. Playback apparatus as claimed in claim 2, wherein the controller is further configured for:

obtaining one or more keywords associated to a program of which the image being played back is part.

7. Playback apparatus as claimed in claim 1, wherein the image data comprises multiple albums for at least one of the objects, each album containing information to recognize a face.

8. Playback apparatus as claimed in claim 1, wherein the images that are played back are part of a video and wherein the controller is configured for:

displaying the information retrieved based on the keyword; and

pausing the video when displaying the information.

10. A computer program comprising computer program code means adapted to perform the steps of the method according to claim 8 when said program is run on a computer, a digital signal processor, a field-programmable gate array, an application-specific integrated circuit, a micro-processor, a micro-controller, or any other form of programmable hardware.

6. (canceled)

9. Method comprising the steps of:

downloading image data of objects in images of a program based on preliminary information about the program,

playing back images from the program;

recognizing an object in an image being played back based on the downloaded image data;

obtaining a keyword associated to the recognized object; and

searching for information based on the keyword.
