In addition, in the first window 81, the inspection image Wk2 at the time of the designated operation is displayed as a still image. At the time of the designation operation, the same inspection image Wk2 as the second window 82 is displayed in the first window 81.

  Next, the inspection object W3 is inspected, and the current inspection image Wk3 is displayed in the second window 82. In addition, the quality determination result of the inspection object W3 is a non-defective product (OK). In the first window 81, the inspection image Wk2 is continuously displayed. The inspection image Wk2 displayed in the first window 81 when inspecting the inspection object W3 is a past inspection image.

  In the display examples shown in FIGS. 8A and 8B, the user performs a designation operation on the inspection image Wk determined to be defective and the second window 82 is displayed. The second window 82 is also displayed when a designation operation is performed on the inspection image Wk that has been performed. In this case, the non-defective inspection image Wk is displayed as a still image on the first window 81 or the second window 82. Further, the second window 82 may be always displayed and the second window 82 may be left blank until a user performs a designation operation.

  Here, the predetermined timing at which the second window 82 is displayed is not limited to the timing at which the designation operation is performed on the inspection image Wk in the first window 81 but may be the timing at which the determination unit 44 determines the defective product.

  When the second window 82 is displayed at the timing of the defective product determination, the display control unit 47 displays the second window 82 at the timing when the determination unit 44 determines the defective product, and the inspection image at the time when the defective product is determined.
