The following describes in detail a method for testing an image processing chip according to an embodiment of the present application with reference to the accompanying drawings.
Please refer to fig. 1, which is a flowchart illustrating a method for testing an image processing chip according to an embodiment of the present disclosure. The method can be applied to electronic equipment, and the electronic equipment can be a mobile phone, a tablet computer, a notebook computer and the like. As shown in fig. 1, the method may include steps 1100-1300, which are described in detail below.
Step 1100, in response to a test request to the image processing chip, replacing preview image data collected by the camera with test image data through the central processing chip.
For example, a tester may send a test request for the image processing chip to the electronic device through the test tool, and after receiving the test request for the image processing chip, the electronic device may control the electronic device to start the camera application program, and replace preview image data acquired by the camera with test image data through the central processing chip when the camera application program is in an open state.
For example, a tester may send a test request for the image processing chip to the electronic device through the test tool, and after receiving the test request for the image processing chip, the electronic device replaces preview image data acquired by the camera with test image data through the central processing chip when the camera application is in an open state.
The test image is a fixed picture pre-stored in the camera application.
For example, when a camera application of the electronic device is in an open state, the electronic device may display a video recording interface, so that the camera captures preview image data in real time. Here, the central processing chip replaces each frame of preview image data collected by the camera with the fixed test image data.
After executing the test request responding to the image processing chip and replacing the preview image data collected by the camera by the central processing chip with the test image data, entering:
In this embodiment, replacing the preview image data collected by the camera with the test image data through the central processing chip in step 1200 may further include the following steps 1210 to 1220:
step 1210, separating the test image data from the operation interface data of the camera application program through the central processing chip.
The operation interface data of the camera application program is interface data of a video recording interface, and the video recording interface includes, for example and without limitation, a "photograph" button, a "video recording" button, a "night scene" button, a "portrait" button, and the like.
In this step 1210, the central processing chip includes the operation interface data and the test image data of the camera application program, where the central processing chip is required to separate the operation interface data and the test image data of the camera application program, and send the operation interface data and the test image data of the camera application program to the image processing chip through different data paths.
Step 1220, sending the separated test image data to the image processing chip through the central processing chip.
The image processing chip may be an external image processing chip (i.e., a chip dedicated to image enhancement processing) that may be processed by the external image processing chip in the electronic device. The image enhancement processing functions described above include, for example and without limitation, noise reduction functions, motion estimation motion compensation functions.
It can be understood that, under the condition that the image enhancement processing function of the image processing chip is in an on state, the image processing chip performs effect enhancement processing on each frame of received test image data, and in order to avoid affecting the received test image data, the electronic device closes the image enhancement processing function of the image processing chip. Under the condition that the image enhancement processing function of the image processing chip is in a closed state, the image processing chip only transmits the received test image data and does not change the content of the test image data.
In this embodiment, the central processing chip sends the separated test image data to the image processing chip through the first data path, and sends the separated operation interface data of the camera application program to the image processing chip through the second data path. The RX1 interface of the image processing chip receives the separated test image data transmitted by the first data path, and the RX0 interface of the image processing chip receives the operation interface data of the separated camera application program.
In this embodiment, after receiving the test image data sent by the central processing chip, the image processing chip divides the test image data into two paths of data, one path of the test image data is transmitted back to the central processing chip for data verification, and the other path of the test image data is mixed with the operation interface data of the camera application program and is superimposed on the operation interface data and sent to the display screen for display.
After the central processing chip sends the test image data to the image processing chip so that the image processing chip sends the test image data back to the central processing chip, entering:
step 1300, verifying the returned test image data through the central processing chip to obtain a test result of the image processing chip.
In this embodiment, after receiving each frame of test image data returned by the image processing chip, the central processing chip verifies each frame of test image data, and further obtains a test result of the image processing chip.
In this embodiment, the step 1300 of verifying the returned test image data by the central processing chip to obtain the test result of the image processing chip may further include the following steps 1310 to 1350:
step 1310, performing cyclic redundancy check analysis on each frame of returned test image data through the central processing chip to obtain a cyclic redundancy check code of each frame of test image data.
The central processing chip performs Cyclic Redundancy Check (CRC) analysis on each frame of the returned test image data to obtain a CRC code of each frame of the test image data.
Step 1320, comparing the cyclic redundancy check code of each frame of the test image data with a preset cyclic redundancy check code through the central processing chip.
The predetermined Cyclic Redundancy Check (CRC) code may be pre-stored in the camera application, and the electronic device has a one-to-one correspondence with the predetermined CRC code.
Illustratively, the central processing chip compares the CRC code of the returned 20 frames of test image data with a preset CRC code, for example.
Step 1330, determining that the test result of the image processing chip is a test pass under the condition that the cyclic redundancy check code of each frame of test image data is the same as the preset cyclic redundancy check code.
Continuing with the example of step 1320, if the CRC code of the 20 frames of the returned test image data is compared with the preset CRC code, and the CRC codes of the 20 frames of the test image data are all the same as the preset CRC code, the central processing chip indicates that the test result of the image processing chip is that the test is passed, that is, the image processing chip has no abnormality.
Step 1340, determining that the test result of the image display chip is that the test is failed under the condition that the cyclic redundancy check code of the at least one frame of test image data is different from a preset cyclic redundancy check code.
Continuing with the example of step 1320, the central processing chip compares the CRC code of the 20 frames of the returned test image data with the preset CRC code, and when the CRC code of at least one frame of the 20 frames of the test image data is different from the preset CRC code, it indicates that the test result of the image processing chip is that the test is failed, that is, the image processing chip is abnormal.
According to the embodiment of the application, after the electronic equipment receives a test request for the image processing chip, the preview image collected by the camera is replaced by the test image data through the central processing chip, the test image data are sent to the image processing chip, the image processing chip transmits the test image data back to the central processing chip, and the central processing chip verifies the transmitted test image data to obtain the test result of the image processing chip. Namely, after the electronic equipment receives the test request of the image processing chip, the test of the image processing chip can be automatically carried out, the usability of the image display chip hardware is detected through the video recording software channel of the electronic equipment, the whole test replaces a manual test method through a software test method, and the test efficiency and the test accuracy of the image processing chip are improved.

(2) The camera application 21 replaces the frame image data filled in the surfeview with the same frame test image data.
(3) The display frame (surface flicker) 22 separates the operation interface data from the test image data of each frame, and transmits the separated test image data to an RX1(Receive X1) interface of the image processing chip 23 through a first data path, and transmits the separated operation interface data to an RX0(Receive X0) interface of the image processing chip 23 through a second data path.
(4) And the image processing chip 23 divides the received test image data into two paths of data under the condition that the image enhancement processing function is closed, wherein one path of test image data is mixed and superposed with the received operation interface data and is transmitted to the display screen 24 for displaying. The other path of test image data is passed back to the camera application 21 for verification.
(5) After receiving each frame of test image data returned by the image processing chip 23, the camera application 21 performs cyclic redundancy check analysis on each frame of returned test image data to obtain a cyclic redundancy check code of each frame of test image data. And comparing the cyclic redundancy check code of each frame of test image data with a preset cyclic redundancy check code, and determining the test result of the image processing chip as a test pass under the condition that the cyclic redundancy check code of each frame of test image data is the same as the preset cyclic redundancy check code. And under the condition that the cyclic redundancy check code of at least one frame of test image data is different from the preset cyclic redundancy check code, determining that the test result of the image display chip is that the test does not pass.
