Abstract

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.

Claims

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.

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.

7. An image forming apparatus, comprising:

an image matching unit configured to match 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

an image shooting unit configured to make 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.

8. The apparatus according to claim 7, further comprising:

an image registering unit configured to obtain the registered image by shooting the object.

9. The apparatus according to claim 7, further comprising:

an image processing unit configured to perform an image processing for an image formed by the shooting.

10. The apparatus according to claim 7, further comprising:

an information prompting unit configured to give an information prompt when an object corresponding to the registered image is not matched with the object in the real-time image.

11. 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

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.

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

the image forming apparatus according to claim 8.
