Abstract

A method for testing a camera module of an electronic device includes following blocks. An analysis module and a control module are installed in the electronic device. A test fixture is utilized to secure the electronic device. The control module instructs the camera module to capture a video and a photo. The analysis module automatically examines whether the video and the photo fall within predetermined parameters. A system associated with above method for testing the camera module of the electronic device is also disclosed.

Claims

1. A system for testing a camera module of an electronic device, the system comprising:

a test fixture comprising a seat for securing the electronic device and a panel pivotally attached to the seat;

a display screen attached to the panel; and

an analysis module;

wherein the camera module is capable of capturing a video and a photo of the display screen, and the analysis module is capable of examining whether the video and the photo fall within predetermined parameters.

2. The system of claim 1, further comprising a control module capable of instructing the camera module to capture the video and the photo.

3. The system of claim 2, further comprising a storage module that stores an exemplar video and an exemplar picture, the analysis module is capable of comparing the video and the photo captured by the camera module with the exemplar video and exemplar picture.

4. The system of claim 3, wherein the control module, the analysis module, and the storage module are installed in the electronic device.

5. The system of claim 1, wherein the display screen is capable of providing motion.

6. The system of claim 1, wherein the test fixture further comprises a rear flange panel and a side flange panel that is substantially perpendicular to the rear flange panel, the seat is configured for supporting the electronic device;

the rear flange panel and the side flange panel are configured for securing the electronic device, and a height of the side flange panel is less than that of the rear flange panel.

7. A method for testing a camera module of an electronic device comprising:

installing an analysis module and a control module in the electronic device;

providing a test fixture to secure the electronic device;

attaching an object to the test fixture;

the object being configured for being captured by the camera module;

instructing the camera module to capture a video and a photo from the object; and

examining whether the video and the photo fall within predetermined parameters.

8. The method of claim 7, wherein the object is a display screen.

9. The method of claim 8, wherein the instructing the camera module to capture the video and the photo comprises:

opening a video capturing window;

adjusting a screen resolution of the camera module;

initializing video parameters;

displaying images of the display screen;

capturing the photo after a first predetermined time period; and

capturing the video after a second predetermined time period.

10. The method of claim 9, wherein the screen resolution of the camera module is adjusted to a maximum value.

11. The method of claim 7, further comprising utilizing a sample electronic device to capture an exemplar video and an exemplar picture.

12. The method of claim 11, wherein the step of examining whether the video and the photo fall within predetermined parameters comprises:

comparing the photo with the exemplar picture;

determining whether differences between the photo and the exemplar picture fall within predetermined ranges.

13. The method of claim 12, further comprising comparing the video with the exemplar video;

if differences between the photo and the exemplar picture and differences between the video and the exemplar video fall within predetermined ranges;

a test pass result is presented;

if not;

a failure result is presented.

14. The method of claims 13, wherein the step of comparing the video captured by the electronic device with the exemplar video comprising comparing frequencies of the video captured by the electronic device and the exemplar video and comparing frames of the video with a corresponding frame of the exemplar video.
