In this case, in the above, whether the object is specified may mean, for example, a category or classification determined for the object. Depending on an embodiment, whether or not the object is specified may be determined not by the electronic device 100 but by an input or request of an external input, for example, a defect inspection requester or terminal for the object. Accordingly, whether or not the object is specified may be determined based on whether or not a learning model usable for defect inspection can be specified for the object to be inspected. That is, when the external input is received, the electronic device 100 may specify and selectively select a learning model based on the received external input. When the object of the object is specified, the electronic device 100 selects and uses a specific first learning model corresponding to the specified object.

Defect inspection can be performed.

Meanwhile, according to an embodiment, when the result of the previously performed defect inspection of the object is equal to or less than a predetermined reference value and the previously selected learning model among the plurality of stored learning models is one of the plurality of first learning models, the electronic device 100 may control to select a second learning model other than another first learning model belonging to the first learning model from among the plurality of stored learning models. According to embodiments, regardless of target specification of an object or when target specification of an object is difficult, the electronic device 100 determines the target object based on at least one of a first learning model and a second learning model set by default. You can also perform a defect inspection on . In this case, the electronic device 100 may perform a corresponding operation by determining whether to define or re-examine an additional learning model based on the object defect inspection result according to a specific learning model set as default. For example, the electronic device 100 performs a defect inspection on an object based on a specific first learning model set as a default, and if the result is equal to or less than a predefined reference value, the electronic device 100 inspects the defect on the object based on the second learning model. can be re-executed. According to an embodiment, the electronic device 100 selects at least two or more specific first learning models from among the first learning models by default to perform defect inspection on the object, and based on a result of the execution, the defect inspection based on the second learning model. You can decide whether or not to do it again. In this case, the selected specific first learning model may be determined based on information about an object subject to defect inspection, a history of previous defect inspection, settings of the electronic device 100, information input by a person requesting inspection or a terminal, and the like. can This may also be used in the same or similar form for specifying a target object.
