Abstract
A device and a method for measuring spatial color characteristic and resolution are provided. The measuring device includes: a light source, a measuring dial plate and a camera under test, wherein the light source has at least two different spectral power distribution characteristics, the measuring dial plate is provided with a through hole penetrating a thickness direction of the measuring dial plate, the light emitted from the light source passes through the through hole, and the surface of the measuring dial plate is set in black color; the measuring dial plate can also be provided with a measuring pattern, the light emitted from the light source passes through a region other than the measuring pattern. With the device provided in the present disclosure, the spatial color and resolution of the camera can be measured simultaneously, which shortens the manufacture cycle of the camera and reduces measurement cost.
