Image processing device, non-transitory computer-readable storage medium, and image processing method

A non-transitory computer-readable storage medium storing a program that causes a computer to execute processing comprising:

• processing captured image data representing a captured image, to generate processed image data representing a processed image, the captured image being an image including an object and a background of the object, the object being a detection target, the processed image being an image in which the object is detected;
• generating expected data representing an expected image on a basis of object data representing a position of the object and background data representing the background, the expected image being a virtual image in which the object is placed at the position on the background;
• and
• comparing the processed image data and the expected data to determine whether or not the object is detected correctly in the processed image data.
