Abstract

A method for processing an image before the image is displayed on a display unit, including: obtaining information of the image and judging the aspect ratio of the image whether equal to the aspect ratio of the display unit; if equality, then display the image on the display unit; else, stretching the image to make the size of the image equal to the size of the display unit; blurring the stretched image; covering the blurred image with the original image and obtaining a combination image; displaying the combination image on the display unit. Present invention also provides an electronic device with the image processing function.

Claims

1. An electronic device capable of processing image, the electronic device comprising:

an input unit configured to generate instructions in response to user'"'"'s operations;

a storage unit configured to store images;

a display unit configured to display the images;

a processing unit comprising;

an obtaining module configured to obtain information of one of the images when the input unit generates an instruction to display the image in response to an operation;

a comparison module configured to obtain an aspect ratio of the image according to the information of the image and an aspect ratio of the display unit and compare the aspect ratio of the image with the aspect ratio of the display unit;

a stretching module configured to stretch the image in order to cover the display area of the display unit if the aspect ratio of the image does not match the aspect ratio of the display unit;

a blurring module configured to blur the stretched image;

a combination module configured to cover the blurred image with the original image to form a combined image;

a display control module configured to control the display unit to display the combined image.

2. The electronic device of claim 1, wherein the blurring module blurs the whole image.

3. The electronic device of claim 1, wherein the blurring module blurs a part of the stretched image corresponding to blank areas that are generated when the aspect ratio of the image does not match the aspect ratio of the display unit.

4. The electronic device of claim 2, wherein the blurring module blurs the image through a blur filter, and the blur filter is selected from the group consisting of a Gaussian blur filter and a mosaic blur filter.

5. The electronic device of claim 3, wherein the blurring module blurs the image through a blur filter, and the blur filter is selected from the group consisting of a Gaussian blur filter and a mosaic blur filter.

6. A method for processing an image before the image is displayed on a display unit of an electronic device, the method comprising:

obtaining information of an image when an instruction to display the image is received;

comparing an aspect ratio of the image with an aspect ratio of the display unit;

stretching the image if the aspect ratio of the image does not match the aspect ratio of the display unit in order to cover the display area of the display unit;

blurring the stretched image;

covering the blurred image with the original image to form a combined image;

displaying the combined image on the display unit.

7. The method of claim 6, wherein the step of blurring the stretched image comprises:

blurring the whole stretched image.

8. The method of claim 7, wherein the step of blurring the stretched image further comprises:

determining blank areas of the display unit;

blurring parts of the stretched image corresponding to the blank areas of the display unit.
