Abstract
The camera view-correction apparatus comprises at least one dividing plate located in the view finder so as to divide the view finder into several regions. Each region has a light source at the far end, so that when all the light sources are successfully observed without being shielded by the dividing plate, it indicates that the optical axis of the view finder is matched with the optical axis of the lens. Alternatively, the camera view-correction apparatus has a plurality of plates located in the view finder. The plates enclose a tunnel free space with a cross shape for the cross-sectional view. Light can pass the tunnel free space and reach the eyes. If the optical axis of the view finder is tilted, some portion of the light is shielded by the plates with respect to the tilted direction.
