1. A learning method causing a statistical model to learn, the statistical model being a statistical model for inputting an image including a subject and outputting a bokeh value indicating bokeh occurring in the image in accordance with a distance to the subject, and the learning method comprising:
acquiring first multi-view images obtained by capturing a first subject from multiple viewpoints by a capture device; and
causing the statistical model to learn, based on a first bokeh value output from the statistical model by inputting a first image of the first multi-view images, and a second bokeh value output from the statistical model by inputting a second image of the first multi-view images,
wherein the causing the statistical model to learn includes:
acquiring (i) a first distance from the capture device to a first subject included in the first image upon capturing the first image, and (ii) a second distance from the capture device to a first subject included in the second image upon capturing the second image, from the first multi-view images;
discriminating a relationship in length between the first distance and the second distance; and
causing the statistical model to learn such that a relationship in magnitude between the first bokeh value and the second bokeh value is equal to the discriminated relationship.
