Claim 11:
12. A method involving a license plate recognition (“LPR”) system comprising a camera device with an image sensor, a processor, and a memory, the method comprising steps to:
receive, by the processor from the memory, a first long-exposure image of a field of view captured by the image sensor with a long-exposure setting;
receive, by the processor from the memory, a first short-exposure image of the same field of view captured by the image sensor with a short-exposure setting, wherein the short-exposure image and the long-exposure image are nearly simultaneously outputted by the image sensor;
detect, by the processor, 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, by the processor, the first license plate and the second license plate in the first short-exposure image, wherein characters of the first license plate have a greater probability of being recognized by a computerized optical character recognition platform in the first long-exposure image than in the first short-exposure image.
