Abrégé

This image restoration device comprises a mask image generation unit, a pixel restoration unit, and an image synthesis unit. The mask image generation unit generates a mask image for an unnecessary object from the input image. The pixel restoration unit first performs down-sampling processing on the input image and the mask image to generate a downsized input image and a downsized mask image by reducing the number of pixels. Next, the pixel restoration unit uses the downsized input image and the downsized mask image to perform object removal processing and pixel restoration processing on a missing region in which the object is removed and generates a downsized restoration image. Then, the pixel restoration unit performs up-sampling processing on the downsized restoration image to generate a restoration image having the same size as that of the original input image. Next, the pixel restoration unit uses the mask image and the restoration image to perform pixel restoration processing on the missing region to generate a final restoration image. The image synthesis unit synthesizes an image by using the input image and the final restoration image.

The purpose of the present disclosure is to achieve, without installing an intra-house communication device and an uninterrupted switching device in a user building, switching of an intra-station communication device that communicates with the user building from an intra-station communication device in a relocation-source building to an intra-station communication device in a relocation-destination building. The present disclosure provides a system for switching a relocation-source intra-station communication device connected to an intra-house communication device to a relocation-destination intra-station communication device, the system comprising a light splitting unit which connects the intra-house communication device to both of the relocation-source intra-station communication device and the relocation-destination intra-station communication device and which has a variable branching ratio, wherein when a light signal level from the light splitting unit becomes lower than a intra-house threshold value determined in advance, the intra-house communication device continuously emits light toward the light splitting unit, stops communication with the relocation-source intra-station communication device, and accumulates data for the intra-station communication device, and the relocation-destination intra-station communication device starts communication with the intra-house communication device after the light signal level from the light splitting unit becomes higher than the intra-house threshold value determined in advance.
