Patent ID: 8363111

Claim:
A resolution test device, adapted for testing a resolution of a camera device, the resolution test device comprising: a test module, adapted for providing a graph and causing the camera device to shoot a test image of the graph; and an analysis module, coupled to the camera device and adapted for capturing the test image shot by the camera device, shifting an analyzing window of the analysis module a specific distance in a first direction from a static area to a first area on the test image, analyzing the first area to generate a first high-pass element, shifting the analyzing window back to the static area, shifting the analyzing window the specific distance in a second direction from the static area to a second area on the test image, analyzing the second area to generate a second high-pass element, generating a third high-pass element according to the first high-pass element and the second high-pass element, and defining the resolution of the camera device according to the third high-pass element.
