Dynamically optimizing photo capture for multiple subjects

Abstract

A user device detects, in a field of view of the camera, a first side of a document, and determines first information associated with the first side of the document. The user device selects a first image resolution based on the first information and captures, by the camera, a first image of the first side of the document according to the first image resolution. The user device detects, in the field of view of the camera, a second side of the document, and determines second information associated with the second side of the document. The user device selects a second image resolution based on the second information, and captures, by the camera, a second image of the second side of the document according to the second image resolution. The user device performs an action related to the first image and the second image.

         6 . The method of  claim 5 , further comprising:
 receiving, from a user via the user device, the first information,
 wherein determining the first information is further based on comparing the first information received from the user to the first information captured by the camera of the user device. 
   
     
     
         7 . The method of  claim 1 , further comprising:
 determining a screen aspect ratio of a display of the user device,
 wherein selecting the first image resolution is further based on the screen aspect ratio. 
   
     
     
         8 . A user device, comprising:
 one or more memories; and   one or more processors, coupled to the one or more memories, configured to:   determine, based on a preview of a first side of a document, first information associated with the first side of the document;   select, based on the first information and a screen aspect ratio of a display of the user device, a first image resolution associated with the user device;   capture, by a camera of the user device, a first image of the first side of the document according to the first image resolution;   capture, by the camera of the user device, a second image of a second side of the document according to a second image resolution associated with the user device; and   perform an action related to the first image and the second image.   
     
     
         9 . The user device of  claim 8 , wherein the one or more processors are further configured to:
 determine a plurality of image resolutions, including the first image resolution and the second image resolution, supported by the user device,
 wherein selecting the first image resolution is further based on determining the plurality of image resolutions. 
   
     
     
         10 . The user device of  claim 8 , wherein the second image resolution is a same image resolution as the first image resolution. 
     
     
         11 . The user device of  claim 8 , wherein the one or more processors are further configured to:
 capture the preview of the first side of the document,
 wherein the preview of the first side of the document includes the first information, and 
 wherein determining the first information is based on capturing the preview of the first side of the document. 
   
     
     
         12 . The user device of  claim 8 , wherein the one or more processors are further configured to:
 receive, from a user via the user device, the first information,
 wherein determining the first information is further based on comparing the first information received from the user to the first information captured by the preview of the first side of the document. 
   
     
     
         13 . The user device of  claim 8 , wherein, to select the first image resolution, the one or more processors are configured to:
 determine a set of optimal image resolutions of a plurality of image resolutions corresponding to the screen aspect ratio of the display of the user device, and   select, based on a threshold associated with a minimum resolution required for capturing the first image of the first side of the document with a threshold amount of data for processing by the user device, the first image resolution from the set of optimal resolutions.   
     
     
         14 . A non-transitory computer-readable medium storing a set of instructions, the set of instructions comprising:
