The image focusing method includes following steps. Firstly, an image is captured. Then, the plural first incident light pixels of the image are collected as a first pattern, and plural second incident light pixels of the image as a second pattern. The first pattern has a first block corresponding to a focusing area of the image. The second pattern has a second block corresponding to the focusing area of the image. Then, a phase difference between the first block and the second block and phase differences between the first block and plural test block are obtained. The test blocks are partially overlapped with the second block or located near the second block. Afterwards, a lens module is moved according to the lowest phase difference."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image focusing method utilizing plural phase differences and image pickup device using the same","description":"An image focusing method and an image pickup device using the image focusing method are provided.
