N2 - In this paper, the implementation to estimate the focus map spatially based on the intentional reblur of one image, which is the only input data, is presented. This enables flexible computation in the spatial domain, rather than the frequency domain. The gradient magnitude term widely used in image processing was used to derive a ratio map. The pixels closer to the focal point of the camera were on the thinner edge in the proposed ratio map. Oppositely, The edge was wider the when the pixels were far from the focal point. The core of proposed algorithm is introduced and the experimental results demonstrate the enhanced effectiveness, quality, and precision of the proposed algorithm.
