The length and width of the first filter 22 are substantially the same as the length and width of the first photosensitive chip 21 . The first optical filter 22 is stacked with the first photosensitive chip 21 in the normal direction of the first photosensitive chip 21 . The edge of the first filter 2 is roughly aligned with the edge of the first photosensitive chip 21 , so that the structure of the first camera 20 is compact.
