摘要：
According to one embodiment, a reading system includes an extractor, a generator, a corrector, and a reader. The extractor extracts a first candidate region from an input image. The first candidate region is of a candidate of a region in which a meter is imaged. The generator generates a rectangle around the first candidate region when an exterior form of the first candidate region is circular. The rectangle corresponds to the exterior form of the first candidate region. The corrector generates a second candidate region by using the generated rectangle to correct the exterior form of the first candidate region to approach a perfect circle. The reader reads, from the second candidate region, a numerical value indicated by the meter.
