Problems solved by technology

However, it is often difficult to accurately detect undesirable phenomena such as colored lines and color casts when shooting in a dark environment or under an LED light source
This is because this phenomenon is related to the algorithm and parameter settings loaded on the mobile phone. When the camera module is tested at the factory, this bad phenomenon is not obvious, and it is easy to miss the inspection and cause the problematic module to be shipped to the customer.

Embodiment 2

[0108] Such as Figure 8 As shown, a camera module detection device is provided, including:

[0109] An acquisition module 801, configured to acquire a captured raw data map from the sensor chip of the camera module to be detected, wherein the gain of the sensor chip is greater than the working gain when the raw data map is taken;

[0110] A detection module 802, configured to use a graph of a preset shape as a unit graph, and detect whether there is an abnormal brightness of the unit graph in the original data graph;

[0111] A determining module 803, configured to determine that the camera module is an unqualified camera module if it exists.

[0112] In the embodiment of the present application, the camera module detection device may be a camera module, a computer, a dedicated tester or a test device integrated into the production line, which is not limited here.

[0113] Since the device introduced in Embodiment 2 of the present invention is the device used to implement t...

Embodiment 3

[0116] Such as Figure 9 As shown, the present embodiment provides an electronic device, including a memory 910, a processor 920, and a computer program 911 stored in the memory 910 and operable on the processor 920. When the processor 920 executes the computer program 911 Implement the following steps:

[0117] Obtain the captured raw data map from the sensor chip of the camera module to be detected, wherein the gain of the sensor chip is greater than the working gain when shooting the raw data map;

[0118] Taking a graph with a preset shape as a unit graph, and detecting whether there is an abnormal brightness of the unit graph in the original data graph;

[0119] If it exists, it is determined that the camera module is an unqualified camera module.

[0120] In this embodiment of the present invention, when the processor 920 executes the computer program 911, any implementation manner in Embodiment 1 of the present invention may be implemented.

[0121]Since the electron...

Embodiment 4

[0124] This embodiment provides a computer-readable storage medium 1000, such as Figure 10 As shown, a computer program 1011 is stored thereon, and it is characterized in that, when the computer program 1011 is executed by the processor, the following steps are implemented:

[0125] Obtain the captured raw data map from the sensor chip of the camera module to be detected, wherein the gain of the sensor chip is greater than the working gain when shooting the raw data map;

[0126] Taking a graph with a preset shape as a unit graph, and detecting whether there is an abnormal brightness of the unit graph in the original data graph;

[0127] If it exists, it is determined that the camera module is an unqualified camera module.

[0128] In a specific implementation process, when the computer program 1011 is executed by a processor, any implementation manner in Embodiment 1 of the present invention may be implemented.

Abstract

The invention discloses a camera module detection method and device, electronic equipment and a medium. The method comprises the steps of obtaining a photographed original data graph from a sensor chip of a to-be-detected camera module, and enabling the gain of the sensor chip to be greater than a working gain when the original data graph is photographed, taking a graph in a preset shape as a unitgraph, and detecting whether the brightness of the unit graph is abnormal or not in the original data graph, and if so, determining that the camera module is an unqualified camera module. The method,the device, the electronic equipment and the medium provided by the invention are used for solving the technical problem of inaccurate detection of problems of bad lines or color cast and the like inthe prior art, and realize the technical effect of improving the detection accuracy of bad lines or color cast and the like.

Description

technical field [0001] The invention relates to the technical field of camera modules, in particular to a camera module detection method, device, electronic equipment and media. Background technique [0002] Before the camera module leaves the factory, performance testing is often required to screen out unqualified camera modules. However, it is often difficult to accurately detect undesirable phenomena such as colored lines and color casts when shooting in a dark environment or under an LED light source. This is because this phenomenon is related to the algorithm and parameter settings loaded on the mobile phone. When the camera module is tested at the factory, this bad phenomenon is not obvious, and it is easy to miss the inspection and cause the problematic module to be shipped to the customer. Contents of the invention [0003] In view of the above problems, the present invention is proposed to provide a camera module detection method, device, electronic device and me...
