In a first aspect, a method for testing a camera module according to an embodiment of the present invention is implemented based on a system shown in fig. 1, where the system includes: the control device 1 and the light source device 2, the control device 1 and the light source device 2 establish communication connection. In some embodiments, the control device 1 may establish a communication connection with the light source device 2 through a serial communication manner. Specifically, the serial communication mode may be implemented by, but not limited to, nine signal lines: two data signal lines, a signal ground line and 6 control signal lines, wherein, realize that control device 1 sends the data of light source equipment 2 through the TxD data signal line, realize that control device 1 receives the data from light source equipment 2 through the RxD data signal line.

The camera module 3 to be tested establishes communication connection with the control device 1 through the test fixture, so that the control device 1 can control the camera module 3 to be tested to shoot test images and acquire the test images shot by the camera module 3 to be tested. The control device 1 is configured to initiate a light source adjustment instruction to the light source device 2; the light source equipment 2 is used for providing a target light source environment required by testing the camera module to be tested according to the light source adjusting instruction initiated by the control equipment 1; the control device 1 is further configured to obtain a test image shot by the camera module 3 to be tested in the target light source environment.
In a second aspect, an embodiment of the present invention provides a method for testing a camera module, which can be applied to the control device shown in fig. 1, and with reference to fig. 2, the method for testing a camera module provided in the embodiment of the present invention includes:
first, step S201 is performed to establish a communication connection between the control device and the light source device.
Specifically, in the present embodiment, the communication related parameters between the control device 1 and the light source device 2 are preset:
(1) bit/second (baud rate) used for defining data transmission rate, and data transmission abnormality can be caused by too high or too low data transmission rate;
(2) data bit (Data bit): 8 bits (ASCII 0 to 255);
(3) parity (Parity bit): is free of
(4) Stop bit (Stop bit): 1 bit, indicating the end of the transmission and providing the computer with the opportunity to correct the clock synchronization.
The control device and the light source device establish communication connection based on preset communication related parameters, and perform information interaction between the control device and the light source device in subsequent S202.
Specifically, before starting to test any camera module to be tested, a communication connection between the camera module to be tested and the control device needs to be established; and then, electrifying and lightening the camera module to be detected so as to enable the camera module to be detected to shoot. After the camera module is lightened, the process of automatically executing S202-S203 once can be triggered based on the starting operation executed by the user on the control equipment, so that each test image required by testing the camera module to be tested is automatically completed, and the user does not need to rely on any operation on the light source equipment and the camera module to be tested in the process of testing the camera module to be tested.
S202, initiating a light source adjusting instruction to the light source equipment based on the communication connection, wherein the light source adjusting instruction is used for controlling the light source equipment to provide a target light source environment required by testing the camera module to be tested.
It should be noted that the crosstalk test performed on the to-be-tested camera module requires multiple test images shot by the to-be-tested camera module in different target light source environments, and in some embodiments, multiple different light source adjustment instructions may be sequentially initiated to the light source device based on communication connection, where the light source adjustment instruction initiated each time is used to control the light source device to provide a corresponding target light source environment. Therefore, the control device can adjust the light source device to one target light source environment required for shooting one of the test images at one time by initiating the light source adjustment instruction for each time, and can change the light source environment provided by the light source device to a plurality of different target light source environments required by initiating different light source adjustment instructions for the light source device for a plurality of times in sequence. Therefore, the number of times of initiating the light source adjustment instruction corresponds to the number of test images taken and the type of target light source environment that needs to be provided, and the specific number of times is not limited herein.
In the embodiment of the invention, the light source adjusting instruction initiated by the control equipment each time represents the light source state and the color temperature value of the target light source environment which need to be provided, so that the light source equipment can be adjusted to the target light source environment at one time according to the light source adjusting instruction without any manual operation of a user on a light source switch and a color temperature adjusting button.
In specific implementation, light source adjustment instructions corresponding to different target light source environments need to be written in advance according to the required light source environments. More specifically, each light source adjustment instruction is configured correspondingly according to the sequence of different target light source environments required to be provided for shooting the test image. The configured plurality of light source adjustment instructions can be sequentially executed in order to change the last target light source environment provided by the light source device to the current target light source environment, and the process is sequentially carried out until the light source device provides the last target light source environment.
For example, 5 light source switches, namely Lamp1 to Lamp5, are arranged on the light source device, so as to correspondingly provide red light, green light, blue light, and Lamp4 and Lamp5 for synthesizing white light. If test images under four different target light source environments, namely a red light environment, a green light environment, a blue light environment and a white light environment, need to be acquired, corresponding four light source adjustment instructions are written in. Referring to table 1 below, the light source state, light source color and color temperature values represented by the respective light source adjustment instructions are as follows:
TABLE 1 light source adjustment Instructions
Of course, what kind of light source state and color temperature value each light source adjustment instruction represents depends on the preset, therefore, the form and the representation content of the light source adjustment instruction in table 1 above are merely for illustration, and it is fully possible to set the light source adjustment instruction in other forms and represent other light source state and color temperature values according to the actual needs in the specific implementation.

Specifically, the first color temperature value is 600K or other color temperature values determined according to actual test requirements. Referring to the example shown in FIG. 4: the light source state of the red light source (i.e., lamp 1) is changed to be on through the first light source adjustment instruction, and the light source states of the other light sources (Lamp 2-Lamp 5) are changed to be off. And the color temperature value of the red light source is modified to be 600K.
Then, step 2 is executed: whether the light source environment currently provided by the light source equipment is the red light environment with the first color temperature value is detected.
Specifically, in step 2, a light source checking instruction is initiated to the light source device to obtain current light source environment parameters of the light source device, where the obtained light source environment parameters include a current light source state and a color temperature value; if the light source environment parameter represents that the light source environment currently provided by the light source equipment has been successfully modified into the red light environment with the first color temperature value, executing the step 3; otherwise, terminating the test of the camera module to be tested.

Referring to the example shown in fig. 4: the light source status of the green light source (i.e., lamp 2) is changed to on by the second light source adjustment command, and the light source status of the remaining light sources (Lamp 1, and Lamp3 to Lamp 5) is changed to off. And, the color temperature value of the green light source is modified to be 1200K.

Step 6: and acquiring a second test image shot by the camera module to be tested in the green light environment of the second color temperature value. Specifically, in step 6, the control device controls the to-be-tested camera module to shoot by initiating a shooting instruction to the to-be-tested camera module, so as to obtain a second test image in a green light environment with a second color temperature value.
And after the step 6, executing a step 7 of initiating a third light source adjusting instruction to the light source device, and controlling the light source device to change the light source state and the color temperature value according to the third light source adjusting instruction so that the light source device provides a blue light environment with a third color temperature value.
Specifically, the third color temperature value is 600K or other color temperature values determined according to actual test requirements. Referring to fig. 4, for example, the light source status of the blue light source (i.e., lamp 3) is changed to on by the third light source adjustment command, and the light source statuses of the remaining light sources (Lamp 1-Lamp 2, and Lamp 4-Lamp 5) are all off. And, the color temperature value of the blue light source is modified to be 600K.
After step 7, step 8 is performed: and detecting whether the light source environment currently provided by the light source equipment is a blue light environment with a third color temperature value.

And 9, acquiring a third test image shot by the camera module to be tested in the blue light environment of the third color temperature value. Specifically, in step 9, the control device controls the to-be-tested camera module to shoot by initiating a shooting instruction to the to-be-tested camera module, so as to obtain a third test image in the blue light environment of the third color temperature value.

Specifically, the fourth color temperature value is 5100K or other color temperature values determined according to actual test requirements. Referring to fig. 4 for example, the light source states of the Lamp4 light source and the Lamp5 light source are changed to be on by the fourth light source adjustment command, and the light source states of the remaining light sources (Lamp 1 to Lamp 3) are all off. And, the color temperature value of the Lamp4 light source is 298K, and the color temperature value of the Lamp5 light source is 316K, so as to synthesize a white light environment with a color temperature value of 5100K.
