ALL-FOCUSED IMAGE GENERATION METHOD, DEVICE USING SAME, AND PROGRAM USING SAME, AND OBJECT HEIGHT DATA ACQUISITION METHOD, DEVICE USING SAME, AND PROGRAM USING SAME

摘要

An all-focused image generation method comprises the steps (i) to (vi). The step (i) is a step of taking L images of an object at different focal positions. The step (ii) is a step of acquiring gray scale images of the object at the respective focal positions. The step (iii) is a step of performing multiresolution transform for the gray scale images. The step (iv) is a step of calculating focal position probability distribution regarding the focal positions, for each pixel position. The step (v) is a step of acquiring an optimal focal position for each of the pixel positions. The step (vi) is a step of generating an in-focus image by providing a pixel corresponding to the acquired pixel value to the pixel position. In the step (v), the optimal focal position is approximately calculated by belief propagation.
