According to one embodiment, a reading system includes a calculator and a determiner. The calculator calculates a total value of luminances and fluctuation of the luminances in at least a portion of a second direction at each of a plurality of points in a first direction for at least a portion of an image subjected to a polar transformation. A meter is imaged in the image and includes a pointer, a display panel, and graduations. The pointer rotates around a rotation axis. The graduations are arranged along a circumferential direction around the rotation axis on the display panel. The polar transformation is referenced to a center of the meter. The first direction corresponds to the circumferential direction. The second direction corresponds to a diametrical direction from the center toward the graduations. The determiner uses the total value and the fluctuation to determine a position at which the pointer exists.
