Abstract: A focus-quality judging method includes the following steps. Firstly, a comparing object including a target area is provided. A reference image pickup device is provided to shoot the comparing object to obtain a standard image including a standard target area image. Then, a first pixel number contained in the standard target area image is counted. The comparing object is shot by a test image pickup device to obtain a test image including a test target area image, wherein the test image has the same resolution as the standard image. Then, a second pixel number contained in the test target area image is counted. The first pixel number contained in the standard target area image is compared with the second pixel number contained in the test target area image. According to the comparing results, it is discriminated whether the test image pickup device performs an accurate focusing operation.
