Abstract
According to one embodiment, an imaging device includes a first optical system including a lens and is configured to control a position of the lens to adjust a focal point. The imaging device includes first storage and a processor. The first storage is configured to store a statistical model generated by learning bokeh which occurs in an image influenced by aberration of a second optical system and changes nonlinearly in accordance with a distance to a subject in the image. The processor is configured to acquire an image influenced by aberration of the first optical system, input the acquired image to the statistical model and acquire distance information, and control the position of the lens included in the first optical system.
