Specifically, as also shown in fig. 4, the control circuit board 201 determines a first region including a first line segment 501 and a second region including a second line segment 502 in the target region 108, wherein the distances of the first line segment 501 from the top and the bottom of the first region are within a distance threshold, and the distances of the second line segment 502 from the top and the bottom of the second region are within a distance threshold; determining the sum of absolute values of gradient values in a direction perpendicular to the third line segment, of the brightness of each pixel on each third line segment parallel to the first line segment 501 in the first region, and determining the sum of absolute values of gradient values in a direction perpendicular to the fourth line segment, of the brightness of each pixel on each fourth line segment parallel to the second line segment 502 in the second region; the determined target region 108 is corrected, wherein the top of the corrected target region 108 is a third line segment with the maximum sum of absolute values of gradient values, and the bottom of the corrected target region 108 is a fourth line segment with the maximum sum of absolute values of gradient values.
