摘要

The present invention is a defect determination device capable of accurately determining a defect. A defect determination device (11) is provided with: a pixel-of-interest selection unit (111) for selecting a single pixel of interest among a plurality of pixels; a reference pixel group extraction unit (112) for extracting a reference pixel group, which is a pixel group composed of a plurality of pixels within a predetermined range of the periphery of the pixel of interest and which is a pixel group that does not contain the pixel of interest and pixels adjacent to the pixel of interest; a defect candidate determination value calculation unit (113) for calculating the average brightness value in the reference pixel group, and deriving a defect candidate determination value corresponding to the average brightness value on the basis of correspondence information set in advance; a differential value calculation unit (114) for calculating a differential value between the average brightness value and the brightness value of the pixel of interest; and a defect candidate determination unit (115) for determining whether the pixel of interest is a defect candidate pixel on the basis of the differential value and the defect candidate determination value.
