The matrix of the point spread function for an X-ray pinhole camera system has been calculated. The computer-simulated pinhole images and real pinhole images measured in laser-plasma experiments have been restored using Lucy-Richardson algorithm. The number of iterations the resolution of the restored imaging and the details of the restore method have been discussed. The reliability of the restoration algorithm is also verified by a simulated optical experiment.
