IMAGE FORMING METHOD AND APPARATUS, AND ELECTRONIC DEVICE
The embodiments of the present invention provide an image forming method and apparatus, and an electronic device. The image forming method includes: matching a real-time image formed by an image forming element with a pre-stored registered image, when a depth of field of the image forming element moves; and making a shooting when an object corresponding to the registered image is matched with an object in the real-time image and the object is within the depth of field of the image forming element. With the embodiments of the present invention, an accurate auto-focusing can be achieved, an effect of highlighting a specific object and clearly imaging the same can be obtained, and an image of higher quality can be formed.
1 . An image forming method, comprising:
matching a real-time image formed by an image forming element with a pre-stored registered image, when a depth of field of the image forming element moves; and
making a shooting when an object corresponding to the registered image is matched with an object in the real-time image and the object is within the depth of field of the image forming element.
2 . The method according to claim 1 , wherein by using a focusing apparatus, the depth of field of the image forming element is controlled to move from near to far, or move to-and-fro between proximal and distal ends.
3 . The method according to claim 1 , wherein said making a shooting comprises shooting is a static image.
4 . The method according to claim 1 , further comprising obtaining the registered image by shooting the object.
5 . The method according to claim 1 , further comprising: performing an image processing for an image formed by the shooting.
6 . The method according to claim 1 , further comprising: giving an information prompt when an object corresponding to the registered image is not matched with the object in the real-time image.
7 . An image forming apparatus, comprising:

a focusing apparatus configured to control the depth of field of the image forming element to move; and
the image forming apparatus according to claim 7 .
12 . The electronic device according to claim 11 , wherein the focusing apparatus is configured to control the depth of field of the image forming element from near to far, or move to-and-fro between proximal and distal ends.
13 . The electronic device according to claim 12 , wherein the focusing apparatus comprises at least one of a Voice Coil Motor (VCM), a T-Lens, a piezo motor drive, a Smooth Impact Drive Mechanism (SIDM) or a liquid actuator.
14 . The method according to claim 1 , wherein said making a shooting comprises shooting a dynamic image.
15 . The method according to claim 1 , further comprising obtaining the registered image by obtaining the registered image transmitted from another device via a communication interface.
16 . The apparatus according to claim 7 , further comprising:
an image registering unit configured to obtain the registered image transmitted by another device via a communication interface.
17 . An electronic device, comprising:
an image forming element having a depth of field;
a focusing apparatus configured to control the depth of field of the image forming element to move; and
