Image processing apparatus and image processing method that determine transmittance of an image based on defect information

An image processing apparatus comprising:

• a processor;
• and
• a memory, including instructions stored thereon, which, when executed by the processor cause the image processing apparatus:
• to acquire a captured image of an inspection target;
• to detect one or more pieces of defect information based on the image;
• to determine a predetermined transmittance of the image, based on a trend in the pieces of the defect information, which is a ratio of the area of the pieces of defect information to the area of the image;
• to set the predetermined transmittance to an upper limit if the ratio is greater than or equal to a first threshold;
• to set the predetermined transmittance between the upper limit and a lower limit if the ratio is greater than or equal to a second threshold or a third threshold, the second and third thresholds being less than the first threshold;
• to set the predetermined transmittance to the lower limit if the ratio is less than the third threshold;
• and
• to display the pieces of detected defect information so as to be superimposed on the image displayed with the predetermined transmittance.

• and
• to display the first and second layers so as to be superimposed on one another or to display the first and third layers so as to be superimposed on one another, respectively.
