This invention relates to the field of
mobile device camera testing technology, and discloses an Android dynamic adaptive screen camera testing
system, including a
light sensing module, an
algorithm module, a parametric template
system, a
distortion compensation engine, and a differential rendering module. The
light sensing module collects ambient absolute
illuminance data; the
algorithm module calculates the ambient
illuminance gradient and controls the
system state flow; the parametric template system reconstructs basic texture parameters based on the gradient to generate a two-dimensional texture of the test pattern; the
distortion compensation engine constructs a non-uniform three-dimensional geometric
mesh model based on the screen curvature
radius and performs
spatial distortion calculations on the vertices of the two-dimensional texture; the differential rendering module obtains a feature
mask image, performs shading
resource reallocation calculations, and sends a timing synchronization trigger command to the camera under test after rendering is completed. This invention can reduce the
impact of sudden changes in external ambient light on the pattern display quality and compensate for the geometric deformation at the edges of curved screens.
