There is provided an inference apparatus. An inference unit performs inference with use of a machine learning model based on a subject region including a subject within an image obtained through shooting, and on a plurality of distance information pieces detected from a plurality of focus detection regions inside the subject region, thereby generating an inference result indicating a distance information piece corresponding to the subject or a distance information range corresponding to the subject. The machine learning model is a model that has been trained to suppress a contribution made to the inference result by one or more distance information pieces that are not based on the subject among the plurality of distance information pieces.

An image capture apparatus detects a subject area from an image that has been shot and enlarges a focus detection area in a case where the subject area is not detected or a reliability that the detected subject area corresponds to an intended subject is determined to be low. The image capture apparatus enlarges the focus detection area based on the distances previously obtained by the obtainment unit.

An image processing apparatus detects, from an image, a subject(s) of a first type and a subject(s) of a second type. The apparatus further detects a posture for each of the subject(s) of the first type. The apparatus then obtains, for each of the subject(s) of the first type, reliability that the subject is a main subject, based on the posture, and obtains a focus condition for each of the subject(s) of the first type and each of the subject(s) of the second type. The apparatus determines, based on the reliability and the focus condition, a main subject from the subject(s) of the first type and the subject(s) of the second type detected from the image.
