Tracker assisted image capture

Abstract

A method for picture processing is described. A first tracking area is obtained. A second tracking area is also obtained. The method includes beginning to track the first tracking area and the second tracking area. Picture processing is performed once a portion of the first tracking area overlapping the second tracking area passes a threshold.

What is claimed is: 
     
         1 . A method, comprising:
 tracking a first tracking area corresponding to an object associated with at least a first frame of a video sequence;   determining, in the first frame, an amount of overlap between the first tracking area and a second area defined at least in part by an action line associated with the first frame; and   increasing a number of frames to record in response to determining that the amount of overlap between the first tracking area and the second area passes a threshold.   
     
     
         2 . The method of  claim 1 , wherein the amount of overlap passes the threshold based on the first tracking area crossing the action line. 
     
     
         3 . The method of  claim 1 , further comprising displaying the action line. 
     
     
         4 . The method of  claim 1 , wherein the action line is set by a user. 
     
     
         5 . The method of  claim 1 , further comprising receiving user input defining the action line relative to at least one frame. 
     
     
         6 . The method of  claim 1 , further comprising receiving a user selection of the first tracking area. 
     
     
         7 . The method of  claim 6 , wherein the user selection is based on a shape. 
     
     
         8 . The method of  claim 7 , wherein the shape is selected by a user. 
     
     
         9 . The method of  claim 6 , wherein the user selection is based on a selection of the object. 
     
     
         10 . The method of  claim 1 , wherein tracking the first tracking area includes tracking the object. 
     
     
         11 . The method of  claim 1 , wherein the action line is part of a bounding box. 
     
     
         12 . The method of  claim 1 , wherein increasing the number of frames including recording a burst of frames. 
     
     
         13 . An apparatus, comprising:
 at least one memory; and   at least one processor coupled to the at least one memory and configured to:
 track a first tracking area corresponding to an object associated with at least a first frame of a video sequence; 
 determine, in the first frame, an amount of overlap between the first tracking area and a second area defined at least in part by an action line associated with the first frame; and 
 increase a number of frames to record in response to determining that the amount of overlap between the first tracking area and the second area passes a threshold. 
   
     
     
         14 . The apparatus of  claim 13 , wherein the amount of overlap passes the threshold based on the first tracking area crossing the action line. 
     
     
         15 . The apparatus of  claim 13 , wherein the at least one processor is configured to cause the action line to be displayed. 
     
     
         16 . The apparatus of  claim 13 , wherein the action line is set by a user. 
     
     
         17 . The apparatus of  claim 13 , wherein the at least one processor is configured to receive user input defining the action line relative to at least one frame. 
     
     
         18 . The apparatus of  claim 13 , wherein the at least one processor is configured to receive a user selection of the first tracking area. 
     
     
         19 . The apparatus of  claim 18 , wherein the user selection is based on a shape. 
     
     
         20 . The apparatus of  claim 19 , wherein the shape is selected by a user. 
     
     
         21 . The apparatus of  claim 18 , wherein the user selection is based on a selection of the object. 
     
     
         22 . The apparatus of  claim 13 , wherein, to track the first tracking area, the at least one processor is configured to track the object. 
     
     
         23 . The apparatus of  claim 13 , wherein the action line is part of a bounding box. 
     
     
         24 . The apparatus of  claim 13 , wherein, to increase the number of frames, the at least one processor is configured to record a burst of frames.
