Detailed Description
The embodiment of the application provides an optical anti-shake test method, device, equipment and medium, solves the technical problem that no system for performing OIS test on a module on a mobile phone exists in the prior art, and provides a technical scheme which can test a single module of a module factory and can test the whole mobile phone of the mobile phone factory.
In order to solve the technical problems, the general idea of the embodiment of the application is as follows:
an optical anti-shake test method comprising:
acquiring first image data acquired in an optical anti-shake test process;
processing the first image data by adopting an image processing flow corresponding to the format of the first image data to obtain second image data in a unified format;
and calculating the data representing the test effect of the optical anti-shake test according to the second image data.
In order to better understand the technical solution, the technical solution will be described in detail with reference to the drawings and the specific embodiments.
First, it is stated that the term "and/or" appearing herein is merely one type of associative relationship that describes an associated object, meaning that three types of relationships may exist, e.g., a and/or B may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.
Example one
Specifically, as shown in fig. 1, an embodiment of the present application provides an optical anti-shake test method, including:
step S101, first image data collected in an optical anti-shake test process are obtained.
In the specific implementation process, the camera single module is only an optical component and cannot store and record shot images, and the whole mobile phone comprises a set of complete shooting system and can store the images shot by the camera module into a storage medium of the mobile phone. Therefore, the processes of image acquisition and image data acquisition are different for the single camera module and the whole mobile phone.
Specifically, if the device to be tested is installed on the mobile terminal (the whole mobile phone), the mobile terminal supplies power to the module to collect image data, and the collected first image data is stored in the mobile terminal. If the equipment to be tested is a single module, the tool supplies power to the module to acquire image data, and the acquired first image data is stored at the equipment end through the tool; if the equipment to be tested is installed on the mobile terminal, the mobile terminal supplies power to the module to collect image data, and the collected first image data is stored in the mobile terminal. The tool is a special hardware device (capable of supplying power to the module to collect image data). Of course, any equipment capable of powering the single module and transmitting image data can be used as the tool.
If the collected first image data is stored in the mobile terminal, the first image data can be transmitted to a computer through a data line and stored on a computer disk in a local file mode, and the test software needs to load the local file to obtain the first image data. Of course, the test software may also directly acquire the first image data stored in the mobile terminal through a data line or a wireless connection. And if the acquired first image data is stored at the equipment end through the tool, accessing the tool through the test software of the equipment end to acquire the acquired first image data and store the acquired first image data at the equipment end. Of course, the first image data in the tool can also be stored on a computer disk through a data line or wireless connection, and the test software loads a local file to acquire the first image data.
In the specific implementation process, images collected by the camera module under three conditions need to be obtained so as to test the optical anti-shake performance of the camera module. Optionally, the test system adds a vibrating table, and acquires image data of image a when the vibrating table closes the OIS and closes, acquires image data of image B when the vibrating table opens the OIS and closes, and acquires image data of image C when the vibrating table opens the OIS and opens.
And step S102, processing the first image data by adopting an image processing flow corresponding to the format of the first image data to obtain second image data in a unified format.
In the specific implementation process, the formats of the images shot by the camera single module and the whole mobile phone are different, the formats of the images are kept uniform through different processing modes, and the consistency of the test method and the comparability of the test can be ensured. The first image data collected by the module factory through the tool is generally image data in RAW format, and the first image data collected by the mobile phone factory through the mobile phone complete machine is generally image data in YUV (Y represents brightness, U, V represents chroma of color) format.
Optionally, when the format of the first image data is RAW format, performing difference processing on the first image data to obtain second image data in RGB format; and when the format of the first image data is YUV format, performing data conversion processing on the first image data to obtain second image data in RGB format. Of course, when the format of the first image data is other format, other image format processing methods may be adopted to convert the format of the first image data into the second image data in RGB format.
Specifically, as shown in fig. 2, a detailed flow chart of step S101 and step S102 is shown. If the single module is used, the RAW image is collected through the tool and then transmitted to a computer through a data line, then the SDK (Software Development Kit) directly accesses the tool, the collected first image data is obtained through the tool, the first image data is imported into a memory buffer of a test system through copying, and finally the first image data is subjected to difference processing to obtain second image data in an RGB format.
If the mobile phone is a complete mobile phone, storing YUV images through the mobile phone, transmitting the YUV images to a computer through a data line, storing the first image data into a local disk of the computer, importing the first image data into a memory buffer of a test system through loading the local image data by test software, and finally performing data conversion processing on the first image data to obtain second image data in an RGB format.
And step S103, calculating data representing the test effect of the optical anti-shake test according to the second image data.
In a specific implementation process, the second image data includes line widths of the image under three conditions, including: the line width of an image A acquired when the vibration table is closed and the optical anti-shake is closed, the line width of an image B acquired when the vibration table is opened and the optical anti-shake is closed, and the line width of an image C acquired when the vibration table is opened and the optical anti-shake is opened. Based on the line widths of the images under the three conditions, compression ratio data representing the test effect of the optical anti-shake test can be calculated. The line width of the image is line width data (or point width data after widening imaging points) of an imaging line in the image due to vibration in the process of shooting the image.
Specifically, the compression ratio data is obtained based on the following formula:
SR＝20*log10((D1-D0)/(D2-D0))
wherein SR is the compression ratio; d0 is the line width of image a; d1 is the line width of image B; d2 is the line width of image C.
The image includes a cross chart pattern and a dot chart pattern. Therefore, the line width of the image can be calculated based on the line width of the cross chart and the line width of the dots chart. When the image is in a cross chart type, the line width of the image is the width of a cross; when the image is in a dot chart mode, the line width of the image is the distance of left and right vibration of the center point of the dot. Of course, the image may be in another chart style, and the line width of the image may be calculated based on the corresponding line width.
For example, as shown in fig. 3 and 4, the line widths of the images under different test conditions are in the cross chart style and the dot chart style, respectively. When the vibration table is closed and the OIS is closed, the line width of the image is D0; when the vibration table is opened and the OIS is closed, the line width of the image is D1; when the vibrating table is open and the OIS is open, the line width of the image is D2.
The following description will help to explain the specific test flow of the method provided in this embodiment with reference to fig. 5 as an example:
first, a test is started, and the test apparatus is made to perform photographing in three states, i.e., three states of the vibration table off OIS off (state 1), the vibration table on IOS off (state 2), and the vibration table on IOS on (state 3). Then, images shot by the test equipment in three states are collected, and image format conversion processing is carried out.
Next, the line widths of the images in the three states are calculated, respectively. In a specific implementation process, the line width of the image can be calculated in different ways based on the pattern of the image.
And then, calculating data representing the test effect of the optical anti-shake test based on the line widths of the images in the three states. Specifically, SR (compression ratio) calculation is performed.
And finally, judging the optical anti-shake effect of the test equipment based on the result of the compression ratio calculation, and finishing the test. Wherein, the larger the compression ratio, the better the optical anti-shake effect.
