Method for adjusting focus position and electronic apparatus

摘要

A method for adjusting focus position and an electronic apparatus are provided. Herein, a depth map is obtained according to a first image and a second image which are captured by a first lens and a second lens, respectively. A plurality of depth values included in the depth map is compared with a depth of field (DOF) table for obtaining a plurality of focus distances. An All-in-Focus (AIF) image is generated according to a plurality of focus images captured by the first lens with the focus distances, respectively. A blur process is executed for a plurality of pixels excluding a focus selected location in the AIF image, so as to obtain an adjusting image.

1. A method for adjusting focus position, for an electronic apparatus, the method comprising:
obtaining a depth map according to a first image and a second image which are respectively captured by a first lens and a second lens, comprises:
simultaneously capturing the first image and the second image by the first lens and the second lens respectively with a base focus;calculating a horizontal shift value of the first image and the second image; andobtaining the depth map by using the first image as a reference according to a lens distance between the first lens and the second lens, the base focus and the horizontal shift value; obtaining a plurality of focus distances by comparing a plurality of depth values included in the depth map with a depth of field table; generating an all-in-focus image according to a plurality of focus images captured by the first lens respectively with the focus distances; and obtaining an adjusting image by executing a blur process for a plurality of pixels excluding a focus selected location in the all-in-focus image.
