Abstract
A camera-testing box for testing optical properties of an image-capturing device includes a box body, a light source, a photographic film, a mask, and a base. The light source is disposed inside the light-free box body. The photographic film is disposed on a side of the light source inside the box body. The mask is disposed on a side of the photographic film away from or facing the light source, and the mask includes a transparent area and a shielding area to reduce flare-causing light reflected by screws and other extraneous objects in the camera-testing box. The base is disposed inside the box body, and on a side of the mask away from the light source. The base supports the to-be-tested image-capturing device.
