parsing, by the device, the image with a two-dimension decoding mode; and
obtaining, by the device, content information of the image;
wherein processing, by the device, the image on the device and obtaining, by the device, the key characteristics of the image comprises:
converting, by the device, the image on the device into a Grayscale image;
detecting, by the device, the Grayscale image;
identifying, by the device, positioning images of the Grayscale image; and
taking, by the device, the positioning images of the Grayscale as the key characteristics of the image.

2. The method according to claim 1 , further comprising:
determining, by the device, whether the key characteristics of the image are characteristics of a two-dimension code;
wherein parsing, by the device, the image with the two-dimension decoding mode comprises:
parsing, by the device, the image with the two-dimension decoding mode if the key characteristics of the image are the characteristics of the two-dimension code.

3. The method according to claim 2 , wherein converting, by the device, the image on the device into the Grayscale image comprises:
reading, by the device, Red Green Blue (RGB) values of pixels of the image;
saving, by the device, the RGB values of the pixels of the image in a binary array; and
converting, by the device, the RGB values in the binary array into YUV values with a YUV algorithm.

4. The method according to claim 3 , wherein determining whether the key characteristics of the image are the characteristics of the two-dimension code comprises:
determining whether the positioning images of the Grayscale image are positioning images of the two-dimension code;
determining that the key characteristics of the image are the characteristics of the two-dimension code if the positioning images of the Grayscale image are the positioning images of the two-dimension code; wherein
the two-dimension code comprises: a Multi-row two-dimension code or a matrix two-dimension code.

5. The method according to claim 4 , wherein before processing, by the device, the image on the device and obtaining the key characteristics of the image, the method further comprises:
receiving a processing instruction of the image; wherein
the processing instruction comprises: an instruction generated by clicking on the image, an instruction generated by pressing the image exceeding a preset length of time or an instruction generated by a selection menu;
wherein if the key characteristics of the image are the characteristics of the two-dimension code, before parsing the image with the two-dimension decoding mode and obtaining the content information of the image, the method further comprises:
outputting an image processing menu to make a response to the processing instruction; wherein the image processing menu comprises a two-dimension reading option;
wherein parsing the image with the two-dimension decoding mode and obtaining the content information of the image comprises:
parsing the image with the two-dimension decoding mode and obtaining the content information of the image if the two-dimension reading option is selected.

6. The method according to claim 5 , wherein parsing the image with the two-dimension decoding mode and obtaining the content information of the image comprises:
positioning an area of the two-dimension code in the image according to position of the positioning images of the Grayscale image;
reading the area of the two-dimension code;
decoding the read two-dimension code; and
obtaining the content information of the image.

7. The method according to claim 1 , wherein after obtaining the content information of the image, the method further comprises:
outputting the content information of the image; wherein
the image comprises: an image on a webpage on the device, an image stored in the device or an image in a file displayed on the device.

8. A device for parsing an image, comprising:
a processing module, to process an image on the device and obtain key characteristics of the image; and
