Claim 0:
1. A license plate recognition (“LPR”) system attached to a law enforcement vehicle, the system comprising:
a camera device comprising an image sensor, the camera device is configured to capture images comprising long-exposure images and short-exposure images with the image sensor, and the image sensor is configured to nearly simultaneously output a long-exposure image of a field of view and a short-exposure image of the field of view;
a memory configured to store the images outputted by the image sensor;
a processor, which is communicatively coupled to the memory, programmed to:
receive, from the memory, a first long-exposure image, wherein the first long-exposure image is captured with a first long-exposure setting of the camera device;
receive, from the memory, a first short-exposure image, wherein the first short-exposure image is captured with a first short-exposure setting of the camera device;
detect a first license plate and a second license plate in the first long-exposure image, wherein the first license plate is in a first portion of the field of view and the second license plate is in a second portion of the field of view, and wherein the first portion of the field of view is different than the second portion of the field of view; and
detect the first license plate and the second license plate in the first short-exposure image, wherein the first license plate is in the first portion of the field of view and the second license plate is in the second portion of the field of view, and wherein characters of the second license plate have a greater probability of being recognized by a computerized optical character recognition platform in the first short-exposure image than in the first long-exposure image.
