Confocal microscopy is a popular technique for 3D imaging of biological specimens. Confocal microscopy images are degraded by residual out of focus light. Several restoration methods have been proposed to reduce these degradations. The major one is Richardson Lucy based deconvolution (RL). Even when employing this method images are still blurry. This is mainly caused due to spherical aberration that depends on the distance from lens. Hence, in the previous study, the restoration method is taking only the depth direction into account. In this paper, predicting PSF more correctly, an image restoring method using RL method and Point Spread Function that is considered based on the depth and horizontal effect of direction, is proposed.
