The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings.

1 is a flowchart of a method for detecting a camera of a mobile terminal according to an embodiment of the present invention. As shown in FIG. 1, the method includes:

Step S101, starting a computer side test tool software module.

The computer side test tool software module includes a download and USB communication driver library module and an image processing module. Start the test tool software module on the computer, the computer initializes the download and USB pass The driver library module and the image processing module, the initialization mainly includes initialization of the test tool software module interface, download, USB plug detection function, and initialization of the USB communication function. At the same time of initialization, the camera detection drive software module stored on the computer side is loaded.

Step S102, the computer downloads the camera detection driver software module into the RAM of the mobile terminal.

Connect the mobile terminal to be tested to the USB port of the computer, and the mobile terminal establishes a physical connection with the computer. The computer side downloading and USB communication interface driver library module detects that the mobile terminal to be accessed via the USB bus, controls the mobile terminal to enter the download mode, and starts interacting with the booting software module on the mobile terminal side, and downloads the camera detection driving software module. Go to the RAM of the mobile terminal.

Step S103: The mobile terminal jumps to the camera to detect that the driver software module starts at the starting position of the RAM storage space, and starts running the camera detection driver software.

Step S104, the camera detection driving software module controls the camera to obtain image data.

The camera detection driving software module on the mobile terminal side directly drives the camera related module, completes the initialization, configuration, start preview, and photographing function of the camera. After obtaining a complete image data of one frame, the photographing is stopped, and the obtained image data is written into the mobile terminal. RAM—The address space available for the segment.

Step S105, the mobile terminal transmits the image data stored in the RAM space of the mobile terminal to the computer.

The camera detection driver software module running on the mobile terminal side uploads the image data written in the RAM space of the mobile terminal to the test tool software module on the computer side through the USB port.

Step S106: The computer-side image processing module processes the image data transmitted by the mobile terminal, and displays the image on the computer interface.

The computer-side image processing module displays the image data uploaded by the mobile terminal through image processing such as format conversion, and displays the image satisfying the condition on the computer display interface. Check calculation The image displayed on the display of the machine has been detected by a single mobile terminal.

As can be seen from the above process, the biggest technical key points of the present invention have three aspects compared to other methods of detecting a camera:

1. The mobile terminal side camera detection driver software module is dynamically loaded into the internal RAM of the mobile terminal in the form of independent software, and does not occupy the non-volatile storage device of the mobile terminal, such as flash EEPROM (Electrically Erasable Programmable Read-Only Memory, EEPROM) Erasable Programmable Read Only Memory) Space. The mobile terminal side camera detects that the driver software module software is powered off or lost, and will not affect the subsequent use of the mobile terminal.

Second, the USB device has the hot plug feature. The computer can monitor the insertion and removal of the mobile terminal through the plugging and unplugging of the USB port, and start or end the test by itself. There is no need to leave a button in the software interface to control the start of the test tool by manual operation. With the end, multi-channel testing can be performed in this way, greatly improving the testing efficiency.

3. The image data obtained by photographing is directly displayed on the computer side display screen. Compared with the display device provided by the mobile terminal, the result is simple and intuitive. According to the effect of the observed image, it can be directly judged whether the camera is qualified.

a camera detection driving software module, configured to control a camera of the mobile terminal to obtain an image Data. The camera detection driver software module is stored on the computer side. After the computer detects that the mobile terminal is connected to the computer through the USB interface, the computer downloads the module to the RAM of the mobile terminal. The mobile terminal runs a camera detection driving software module in the RAM, and the module interacts with the computer side downloading and the USB communication driving library module through the USB port, and receives a test command issued by the computer side testing tool software module to complete the initialization and setting of the camera. And the photographing function, the image data obtained by photographing is transmitted back to the computer side.

The download and USB communication driver library module is used to download and temporarily store the camera detection driver software module into the RAM of the mobile terminal. The module completes the download and initialization of the USB communication driver, and performs command and data interaction with the mobile terminal through the USB port of the computer, downloads the camera detection driver software module to the RAM of the mobile terminal, and the RAM type may be SRAM (Static RAM, static random access memory) /PSRAM (Pseudo Static RAM) / DRAM (Dynamic RAM) / SDRAM (Synchronous Dynamic RAM) / DDRAM (Double Data Rate SDRAM) Random access memory, etc., and receive response and detection data transmitted by the mobile terminal during the detection process.

The image processing module is configured to perform corresponding processing on the image data uploaded by the mobile terminal. The image data obtained by the computer from the mobile terminal side through the download and USB communication driver library module is the original data obtained by the camera photographing, and the image processing module needs to process the original data, but does not optimize the image, or according to the image itself. The image quality control image is directly imaged and displayed on a computer monitor to faithfully reflect the true effect of the image to determine the quality of the camera.

And a mobile terminal, configured to use the camera detection driving software module to control its camera to obtain image data, and upload the image data to the computer. The mobile terminal includes a boot software module.

The booting software module is started when the mobile terminal side is powered on, and the module interacts with the downloading and USB communication driver library module on the computer side through the USB port, and receives the code of the camera detecting driver software module of the computer side and stores it in the RAM inside the mobile terminal. At the same time, the mobile terminal is guided to jump to run the camera detection driver software module. When the mobile terminal is powered off, the camera detecting driver software module in the RAM is lost.

In summary, the present invention downloads the camera detection driving software module into the mobile terminal RAM, and runs the camera detection driving software module in the RAM to directly drive the camera to take a photo, and the obtained image data is passed through the USB port. Uploaded to the computer side, enlarged display on the computer's display screen, intuitively judge whether the image quality is qualified and determine whether the camera is qualified. The invention solves the problem that the test camera of the mobile terminal has a long time and low efficiency, and the need of the auxiliary detection tool makes the test cost high, and has the beneficial effects of short detection time, low cost and good effect.
