Detection method, imaging apparatus, and program

An imaging apparatus comprising:

• an imaging element that has a first pixel for generating a first signal and second and third pixels for generating second and third signals for detecting a phase difference;
• a memory that stores a model trained through machine learning;
• and
• a processor,
• wherein the processor is configured to execute:
• an input process of inputting a second image based on the second signal, a third image based on the third signal, or a fourth image based on the second signal and the third signal to the model as an input image;
• a subject detection process of detecting a subject included in a first image generated by the first signal, through the model on which the input process is executed;
• and
• a first focusing position detection process of detecting a focusing position with respect to the subject, through the model on which the input process is executed,
• wherein, in the input process, the input image is rotated and input to the model, and
• in the first focusing position detection process, the focusing position is detected based on the rotated input image.

A non-transitory computer-readable storage medium storing a program for operating an imaging apparatus including an imaging element that has a first pixel for generating a first signal and second and third pixels for generating second and third signals for detecting a phase difference, and a memory that stores a model trained through machine learning, the program causing the imaging apparatus to execute:

• an input process of inputting a second image based on the second signal, a third image based on the third signal, or a fourth image based on the second signal and the third signal to the model as an input image;
• a subject detection process of detecting a subject included in a first image generated by the first signal, through the model on which the input process is executed;
• and
• a first focusing position detection process of detecting a focusing position with respect to the subject, through the model on which the input process is executed,
• wherein, in the input process, the input image is rotated and input to the model, and
• in the first focusing position detection process, the focusing position is detected based on the rotated input image.
