摘要

According to the embodiment, the tablet inspecting apparatus includes: a differential image generating unit that generates a horizontal differentiated image which is a differential image in the horizontal direction of the captured image of the tablet and a vertical differentiated image which is a differential image in the vertical direction; An inner product image generating unit for generating an inner product image based on an inner product between a reference image having a vector oriented in a tangential direction of a concentric circle centered on a position and a horizontal differentiated image and a previous vertical differential image; A logical product image generating unit for generating a logical product image based on the logical product of the mask and the inner product image; a threshold image generating unit for generating a threshold image in which the logical product image is binarized based on a predetermined threshold value; And a determination unit that determines the presence or absence of a defect in the tablet based on a labeling processing result on the threshold image.
