A brain image reconstruction apparatus can reconstruct a brain image as a sharper image. A brain image reconstruction apparatus has a data acquisition unit that acquires brain activity data of a user； a brain image reconstructor that detects image information from the brain activity data and constructs a brain image； a linguistic information detector that detects linguistic information from the brain activity data； an image database that stores sample images corresponding to the linguistic information； and an image processor that superimposes the sample image with the brain image, and constructs a process image.
