Abstract
A mark detecting apparatus includes an imaging unit configured to generate an alignment mark image by imaging of an alignment mark on an object, a detecting unit configured to detect the alignment mark in the alignment mark image, and an adjusting unit configured to adjust a parameter relating to the imaging, based on a learning model generated by learning using the alignment mark image in which the alignment mark could not be detected and a first parameter as the parameter for the imaging of the alignment mark image in which the alignment mark could be detected. The adjusting unit acquires a second parameter as a result of inference processing based on the learning model. The imaging unit performs the imaging in a state where the parameter is adjusted to the second parameter.
