METHOD FOR OBTAINING IMAGE AND IMAGE PICKUP DEVICE AND ELECTRONIC DEVICE USING THE SAME

---

Abstract

---

The present invention provides a method for measuring a depth of field of an image, including: (a) picking up a first image having a first resolution at a first position; (b) driving the optical lens to move to a second position in a direction along a non-optical axis, and picking up a second image having a second resolution at the second position; and (c) synthesizing the first image and the second image, so as to obtain a third image having a third resolution, where the third resolution is greater than the first resolution and the second resolution. In addition, the present invention also provides an image pickup device and an electronic device using the method.
