摘要
Two wells are selected (step S10) and upper, lower, left, and right logical edge coordinates of the two wells are calculated (step S20). An image of a portion near each set of logical edge coordinates is captured (step S30), and a rectangular separability filter is applied to each captured image and for each captured image, coordinates of a center position of the rectangular separability filter obtained when a peak value of a separability is obtained are detected as temporary edge coordinates (step S40). Thereafter, actual center coordinates are calculated for each well selected in step S10, based on upper, lower, left, and right temporary edge coordinates (step S60). Finally, the amount of positional displacement of a well plate from an ideal placement state is calculated based on the center coordinates of the two wells selected in step S10 (step S70).
