Abstract: According to one embodiment, an image processing device includes storage and a processor. The storage stores a statistical model generated by learning bokeh produced in a first image affected by aberration of an optical system, the bokeh changing nonlinearly in accordance with a distance to a subject in the first image. The processor obtains a second image affected by the aberration of the optical system. The processor inputs the second image to the statistical model and obtains distance information indicating a distance to a subject in the second image.

Abstract: According to an embodiment, an image display device includes an optical element, a voltage controller, and a display. Regarding the optical element, the refractive-index distribution changes according to the voltage applied thereto. The voltage controller controls, in a first mode, the voltage applied to the optical element in such a way that a first-type refractive-index distribution is achieved which acts as a first-type Fresnel lens; and controls, in a second mode that is different than the first mode, the voltage applied to the optical element in such a way that a second-type refractive-index distribution is achieved which acts as a second-type Fresnel lens having a greater number of steps than the first-type Fresnel lens. The display is disposed on the back side of the optical element and displays images.

Abstract: According to one embodiment, an image processing device includes first storage and a processor. The first storage is configured to store a first statistical model generated by learning bokeh which occurs in a first image. The processor is configured to acquire a second image, acquire a bokeh value which indicates bokeh occurring in the second image and an uncertainty level which indicates a level of uncertainty for the bokeh value, generate a first bokeh map based on the bokeh value and uncertainty level, and acquire a second bokeh map obtained by interpolating a bokeh value with respect to the first bokeh map. The bokeh value and the uncertainty level are output from the first statistical model by inputting the second image into the first statistical model.
